+Overview of Tajo Tables
+***********************
+
+========
+Overview
+========
+
+===========
+Tablespaces
+===========
+
+Tablespaces is a physical location where files or data objects representing data rows can be stored. Once defined, a tablespace can be referred to by a name when creating a database or a table. Especially, it is very useful when a Tajo cluster instance should use heterogeneous storage systems such as HDFS, MySQL, and Oracle because each tablespace can be specified to use a different storage system. 
+
+Please refer to :doc:`/table_management/tablespaces` if you want to know more information about tablespaces.
+
+=============
+Managed Table
+=============
+
+``CREATE TABLE`` statement lets you create a table located in the warehouse directory specified by the configuration property ``tajo.warehouse.directory`` or ``${tajo.root}/warehouse`` by default. For example:
+
+.. code-block:: sql
+
+ CREATE TABLE employee (
+  id int,
+  name text,
+  age
+ );
+
+
+==============
+External Table
+==============
+
+``CREATE EXTERNAL TABLE`` statement lets you create a table located in a specify location so that Tajo does not use a default data warehouse location for the table. External tables are in common used if you already have data generated. LOCATION clause must be required for an external table. 
+
+.. code-block:: sql
+
+ CREATE EXTERNAL TABLE employee (
+  id int,
+  name text,
+  age
+ ) LOCATION 'hdfs://table/path';
+
+
+The location can be a directory located in HDFS, Amazon S3, HBase, or local file system (if a Tajo cluster runs in a single machine). URI examples are as follows:
+
+ * HDFS - ``hdfs://hostname:8020/table1``
+ * Amazon S3 - ``s3://bucket-name/table1``
+ * local file system - ``file:///dir/table1``
+ * Openstack Swift - ``swift://bucket-name/table1``
+
+Table Properties
+================
+All table formats provide parameters for enabling or disabling features and adjusting physical parameters.
+The ``WITH`` clause in the CREATE TABLE statement allows users to set those properties.
+
+The following example is to set a custom field delimiter, NULL character, and compression codec:
+
+.. code-block:: sql
+
+ CREATE TABLE table1 (
+  id int,
+  name text,
+  score float,
+  type text
+ ) USING TEXT WITH('text.delimiter'='\u0001',
+                   'text.null'='\\N',
+                   'compression.codec'='org.apache.hadoop.io.compress.SnappyCodec');
+
+Each physical table layout has its own specialized properties. They will be addressed in :doc:`/table_management/data_formats`.
+
+
+Common Table Properties
+=======================
+
+There are some common table properties which are used in most tables.
+
+Compression
+-----------
+
+See :doc:`compression`.
+
+Time zone
+---------
+
+In Tajo, a table property ``timezone`` allows users to specify a time zone that the table uses for reading or writing. 
+
+You can specify a table time zone as follows:
+
+.. code-block:: sql
+
+   CREATE EXTERNAL TABLE table1 (
+    t_timestamp  TIMESTAMP,
+    t_date    DATE
+   ) USING TEXT WITH('timezone'='ASIA/Seoul') LOCATION '/path-to-table/'
+ 
+
+In order to learn time zone, please refer to :doc:`/time_zone`.

+***********
+Tablespaces
+***********
+
+Tablespaces in Tajo allow users to define locations in the storage system where the files or data objects representing database objects can be stored.
+Once defined, a tablespace can be referred to by name when creating a database or a table.
+Especially, it is very useful when a Tajo cluster instance should use heterogeneous storage systems such as HDFS, MySQL, and Oracle.
+
+============================================
+External Table, Managed Table and Tablespace
+============================================
+
+Tajo has two types of table. One is external table. It needs **location** property when the table is created. Using this property, you can create an external table indicating existing external data source.
+For example, if there is already your data as Text/JSON files or HBase table, you can register it as tajo external table.
+Other one is managed table, which means internal table, that is created in a speficied tablespace.
+
+Tablespace is a pre-defined physical location where data stored on. It is supported for only managed tables.
+When you create a managed table, you can use the **tablespace** keyword to specify the location of data will be stored.
+If the tablespace is not specified, the default tablespace of the table's database is used.
+
+.. note::
+
+  For creating a table, see :doc:`/sql_language/ddl`.
+
+=============
+Configuration
+=============
+
+By default, Tajo use ``${tajo.rootdir}/warehouse`` in :doc:`conf/tajo-site.xml</configuration/tajo-site-xml>` as a default tablespace. It also allows users to register additional tablespaces using ``storage-site.json`` file like below.
+
+---------------------------
+conf/storage-site.json file
+---------------------------
+
+The configuration file has the following struct:
+
+.. code-block:: json
+
+  {
+    "spaces": {
+      "${tablespace_name}": {
+        "uri": "hbase:zk://quorum1:port,quorum2:port/"
+      }
+    }
+  }
+
+The following is an example for two tablespaces for hbase and hdfs:
+
+.. code-block:: json
+
+  {
+    "spaces": {
+      "hbase_cluster1": {
+        "uri": "hbase:zk://quorum1:port,quorum2:port/"
+      },
+
+      "ssd": {
+        "uri": "hdfs://host:port/data/ssd"
+      }
+    }
+  }
+
+For more details, see :doc:`conf/storage-site.json</configuration/storage-site-json>`.
+
+
+.. note::
+
+  Also, each tablespace can use different storage type. Please see :doc:`/storage_plugins` if you want to know more information about it.

+****
+TEXT
+****
+
+A character-separated values plain text file represents a tabular data set consisting of rows and columns.
+Each row is a plain text line. A line is usually broken by a character line feed ``\n`` or carriage-return ``\r``.
+The line feed ``\n`` is the default delimiter in Tajo. Each record consists of multiple fields, separated by
+some other character or string, most commonly a literal vertical bar ``|``, comma ``,`` or tab ``\t``.
+The vertical bar is used as the default field delimiter in Tajo.
+
+============================
+How to Create a TEXT Table ?
+============================
+
+If you are not familiar with the ``CREATE TABLE`` statement, please refer to the Data Definition Language :doc:`/sql_language/ddl`.
+
+In order to specify a certain file format for your table, you need to use the ``USING`` clause in your ``CREATE TABLE``
+statement. The below is an example statement for creating a table using *TEXT* format.
+
+.. code-block:: sql
+
+ CREATE TABLE
+  table1 (
+    id int,
+    name text,
+    score float,
+    type text
+  ) USING TEXT;
+
+===================
+Physical Properties
+===================
+
+Some table storage formats provide parameters for enabling or disabling features and adjusting physical parameters.
+The ``WITH`` clause in the CREATE TABLE statement allows users to set those parameters.
+
+*TEXT* format provides the following physical properties.
+
+* ``text.delimiter``: delimiter character. ``|`` or ``\u0001`` is usually used, and the default field delimiter is ``|``.
+* ``text.null``: ``NULL`` character. The default ``NULL`` character is an empty string ``''``. Hive's default ``NULL`` character is ``'\\N'``.
+* ``compression.codec``: Compression codec. You can enable compression feature and set specified compression algorithm. The compression algorithm used to compress files. The compression codec name should be the fully qualified class name inherited from `org.apache.hadoop.io.compress.CompressionCodec <https://hadoop.apache.org/docs/current/api/org/apache/hadoop/io/compress/CompressionCodec.html>`_. By default, compression is disabled.
+* ``text.serde``: custom (De)serializer class. ``org.apache.tajo.storage.text.CSVLineSerDe`` is the default (De)serializer class.
+* ``timezone``: the time zone that the table uses for writting. When table rows are read or written, ```timestamp``` and ```time``` column values are adjusted by this timezone if it is set. Time zone can be an abbreviation form like 'PST' or 'DST'. Also, it accepts an offset-based form like 'UTC+9' or a location-based form like 'Asia/Seoul'.
+* ``text.error-tolerance.max-num``: the maximum number of permissible parsing errors. This value should be an integer value. By default, ``text.error-tolerance.max-num`` is ``0``. According to the value, parsing errors will be handled in different ways.
+
+  * If ``text.error-tolerance.max-num < 0``, all parsing errors are ignored.
+  * If ``text.error-tolerance.max-num == 0``, any parsing error is not allowed. If any error occurs, the query will be failed. (default)
+  * If ``text.error-tolerance.max-num > 0``, the given number of parsing errors in each task will be pemissible.
+
+* ``text.skip.headerlines``: Number of header lines to be skipped. Some text files often have a header which has a kind of metadata(e.g.: column names), thus this option can be useful.
+
+The following example is to set a custom field delimiter, ``NULL`` character, and compression codec:
+
+.. code-block:: sql
+
+ CREATE TABLE table1 (
+  id int,
+  name text,
+  score float,
+  type text
+ ) USING TEXT WITH('text.delimiter'='\u0001',
+                   'text.null'='\\N',
+                   'compression.codec'='org.apache.hadoop.io.compress.SnappyCodec');
+
+.. warning::
+
+  Be careful when using ``\n`` as the field delimiter because *TEXT* format tables use ``\n`` as the line delimiter.
+  At the moment, Tajo does not provide a way to specify the line delimiter.
+
+=====================
+Custom (De)serializer
+=====================
+
+The *TEXT* format not only provides reading and writing interfaces for text data but also allows users to process custom
+plain text file formats with user-defined (De)serializer classes.
+With custom (de)serializers, Tajo can process any text files no matter which the internal structure is.
+
+In order to specify a custom (De)serializer, set a physical property ``text.serde``.
+The property value should be a fully qualified class name.
+
+For example:
+
+.. code-block:: sql
+
+ CREATE TABLE table1 (
+  id int,
+  name text,
+  score float,
+  type text
+ ) USING TEXT WITH ('text.serde'='org.my.storage.CustomSerializerDeserializer')
+
+
+==========================
+Null Value Handling Issues
+==========================
+In default, ``NULL`` character in *TEXT* format is an empty string ``''``.
+In other words, an empty field is basically recognized as a ``NULL`` value in Tajo.
+If a field domain is ``TEXT``, an empty field is recognized as a string value ``''`` instead of ``NULL`` value.
+Besides, You can also use your own ``NULL`` character by specifying a physical property ``text.null``.
+
+======================================
+Compatibility Issues with Apache Hive™
+======================================
+
+*TEXT* tables generated in Tajo can be processed directly by Apache Hive™ without further processing.
+In this section, we explain some compatibility issue for users who use both Hive and Tajo.
+
+If you set a custom field delimiter, the *TEXT* tables cannot be directly used in Hive.
+In order to specify the custom field delimiter in Hive, you need to use ``ROW FORMAT DELIMITED FIELDS TERMINATED BY``
+clause in a Hive's ``CREATE TABLE`` statement as follows:
+
+.. code-block:: sql
+
+ CREATE TABLE table1 (id int, name string, score float, type string)
+ ROW FORMAT DELIMITED FIELDS TERMINATED BY '|'
+ STORED AS TEXT
+
+To the best of our knowledge, there is not way to specify a custom ``NULL`` character in Hive.

+******************
+Time Zone
+******************
+
+Time zone affects ``Timestamp`` data type and operations (e.g., ``to_char``). Tables can have different time zones. Internally, Tajo translates all table rows to UTC values and processes them. It becomes easier for Tajo to handle multiple different time zones.
+
+In Tajo, there are some time zong settings.
+
+========================
+Server Cluster Time Zone
+========================
+
+One Tajo cluster has a system time zone which globally affects all tables in which the table property 'time zone' are not specified.
+
+You can set the system time zone in *conf/tajo-site.xml* file as follows:
+
+**tajo-site.xml**
+
+.. code-block:: xml  
+
+  <name>tajo.timezone</name>
+  <value>GMT+9</value>
+
+
+==================
+Table Time Zone
+==================
+
+In Tajo, a table property ``timezone`` allows users to specify a time zone that the table uses for reading or writing. 
+When each table row are read or written, ```timestamp``` column values are adjusted by a given time zone if it is set.
+
+You can specify a table time zone as follows:
+
+.. code-block:: sql
+
+   CREATE EXTERNAL TABLE table1 (
+    t_timestamp  TIMESTAMP,
+    t_date    DATE
+   ) USING TEXT WITH('timezone'='ASIA/Seoul') LOCATION '/path-to-table/'
+ 
+
+In order to learn table properties, please refer to :doc:`/table_management/table_overview`.
+
+==================
+Client Time Zone
+==================
+
+Each client has its own time zone setting. It translates retrieved timestamp and time values by time zone. In order to set client time zone, you should set the session variable ``TIMEZONE``. There are some ways to set this session variable.
+
+In ``tsql``, you can use ``\set timezone`` meta command as follows:
+
+**tsql**
+
+.. code-block:: sh
+
+  default> \set timezone GMT+9
+
+
+The following ways use SQL statements. So, this way is available in ``tsql``, JDBC, and Tajo Java API.
+
+**SQL**
+
+.. code-block:: sql
+
+  SET TIME ZONE 'GMT+9';
+
+  or
+
+  SET SESSION TIMEZONE TO 'GMT+9';
+
+============
+Time Zone ID
+============
+
+Time zone can be an abbreviation form like 'PST' or 'DST'. Also, it accepts an offset-based form like 'GMT+9' or UTC+9' or a location-based form like 'Asia/Seoul'. 
+
+.. note::
+
+  In many cases, offset-based forms or locaion-based forms are recommanded. In order to know the list of time zones, please refer to `List of tz database time zones <http://en.wikipedia.org/wiki/List_of_tz_database_time_zones>`_
+
+.. note::
+
+  Java 6 does not recognize many location-based time zones and an offset-based timezone using the prefix 'UTC'. We highly recommanded using the offset-based time zone using the prefix 'GMT'. In other words, you should use 'GMT-7' instead of 'UTC-7' in Java 6.
+
+=====================
+Examples of Time Zone
+=====================
+
+For example, consider that there is a list of delimited text lines where each rows are written with ``Asia/Seoul`` time zone (i.e., GMT + 9).
+
+.. code-block:: text
+
+  1980-4-1 01:50:30.010|1980-04-01
+  80/4/1 1:50:30 AM|80/4/1
+  1980 April 1 1:50:30|1980-04-01
+
+
+In order to register the table, we should put a table property ``'timezone'='Asia/Seoul'`` in ``CREATE TABLE`` statement as follows:
+
+.. code-block:: sql
+
+ CREATE EXTERNAL TABLE table1 (
+  t_timestamp  TIMESTAMP,
+  t_date    DATE
+ ) USING TEXT WITH('text.delimiter'='|', 'timezone'='ASIA/Seoul') LOCATION '/path-to-table/'
+
+
+By default, ``tsql`` and ``TajoClient`` API use UTC time zone. So, timestamp values in the result are adjusted by the time zone offset. But, date is not adjusted because date type does not consider time zone.
+
+.. code-block:: sql
+
+  default> SELECT * FROM table1
+  t_timestamp,            t_date
+  ----------------------------------
+  1980-03-31 16:50:30.01, 1980-04-01
+  1980-03-31 16:50:30   , 1980-04-01
+  1980-03-31 16:50:30   , 1980-04-01
+
+In addition, users can set client-side time zone by setting a session variable 'TZ'. It enables a client to translate timestamp or time values to user's time zoned ones.
+
+.. code-block:: sql
+
+  default> SET TIME ZONE 'Asia/Seoul'
+  default> SELECT * FROM table1
+  t_timestamp,            t_date
+  ----------------------------------
+  1980-04-01 01:50:30.01, 1980-04-01
+  1980-04-01 01:50:30   , 1980-04-01

+*********************************
+
+
+-----------------------------------------------
+Basic usages
+-----------------------------------------------
+
+
+``-f`` command allows tsql to execute more than one SQL statements stored in a text file as follows:
+
+.. code-block:: sql
+
+  $ cat aggregation.sql
+  select count(*) from table1;
+  select sum(score) from table1;
+
+  $ bin/tsql -f aggregation.sql

+Setting parameter value in SQL file
+-----------------------------------------------
+
+If you wish to set a parameter value in the SQL file, you can set with the -param key=value option. When you use this feature, you have to use the parameter in the file as follows:
+
+.. code-block:: sql
+
+  ${paramter name}
+
+
+You have to put the parameter name in braces and you must use the $ symbol for the prefix as follows:
+
+.. code-block:: sql
+
+  $ cat aggregation.sql
+  select count(*) from table1 where id = ${p_id};
+
+  $ bin/tsql -param p_id=1 -f aggregation.sql

+*****************************
+Introducing to TSQL
+*****************************
+
+==========
+Synopsis
+==========
+
+.. code-block:: bash
+
+  bin/tsql [options] [database name]
+
+If a *database_name* is given, tsql connects to the database at startup time. Otherwise, tsql connects to ``default`` database.
+
+Options
+
+* ``-c "quoted sql"`` : Execute quoted sql statements, and then the shell will exist.
+* ``-f filename (--file filename)`` : Use the file named filename as the source of commands instead of interactive shell.
+* ``-h hostname (--host hostname)`` : Specifies the host name of the machine on which the Tajo master is running.
+* ``-p port (--port port)`` : Specifies the TCP port. If it is not set, the port will be 26002 by default.
+* ``-conf configuration (--conf configuration)`` : Setting Tajo configuration value.
+* ``-param parameter (--param parameter)`` : Use a parameter value in SQL file.
+* ``-B (--background)`` : Execute as background process.
+
+===================
+Entering tsql shell
+===================
+
+If the hostname and the port num are not given, tsql will try to connect the Tajo master specified in ${TAJO_HOME}/conf/tajo-site.xml. ::
+
+  bin/tsql
+
+  default>
+
+If you want to connect a specified TajoMaster, you should use '-h' and (or) 'p' options as follows: ::
+
+  bin/tsql -h localhost -p 9004
+
+  default>
+
+The prompt indicates the current database.

+Meta Commands
+*********************************
+
+
+In tsql, any command that begins with an unquoted backslash ('\\') is a tsql meta-command that is processed by tsql itself.
+
+In the current implementation, there are meta commands as follows: ::

+Basic usages
+-----------------------------------------------
+
+``\l`` command shows a list of all databases as follows: ::
+
+  default> \l
+  default
+  tpch
+  work1
+  default>
+
+
+
+``\d`` command shows a list of tables in the current database as follows: ::
+
+  default> \d
+  customer
+  lineitem
+  nation
+  orders
+  part
+  partsupp
+  region
+  supplier
+
+
+``\d [table name]`` command also shows a table description as follows: ::
+
+  default> \d orders
+
+  table name: orders
+  table path: hdfs:/xxx/xxx/tpch/orders
+  store type: TEXT
+  number of rows: 0
+  volume (bytes): 172.0 MB
+  schema:

+  o_orderpriority TEXT
+  o_clerk TEXT
+  o_shippriority  INT4
+  o_comment       TEXT
+
+
+
+The prompt ``default>`` indicates the current database. Basically, all SQL statements and meta commands work in the current database. Also, you can change the current database with ``\c`` command.

+*********************************
+Session Variables
+*********************************
+
+Once a tajo client connects to the Tajo master, it assigns a unique session. This session is kept until the client is disconnected or it is expired.
+
+For the sake of more convenient user configuration, Tajo provides `session variables`.
+With session variables, different configurations are allowed for each session.
+
+``tsql`` provides the meta command ``\set`` to manipulate session variables. Just ``\set`` command shows all session variables. ::
+
+  default> \set
+  'name1'='val1'
+  'name2'='val2'
+  'name3'='val3'
+       ...
+
+``\set key val`` will set the session variable named *key* with the value *val*. ::
+
+  default> \set
+  'CURRENT_DATABASE'='default'
+
+  default> \set key1 val1
+
+  default> \set
+  'CURRENT_DATABASE'='default'
+  'key1'='val1'
+
+
+Also, ``\unset key`` will unset the session variable named *key*.
+
+
+Currently, tajo provides the following session variables.
+
+.. describe:: BROADCAST_NON_CROSS_JOIN_THRESHOLD
+
+A threshold for non-cross joins. When a non-cross join query is executed with the broadcast join, the whole size of broadcasted tables won't exceed this threshold.
+
+  * Configuration name: :ref:`tajo.dist-query.broadcast.non-cross-join.threshold-kb`
+  * Property value: Integer
+  * Unit: KB
+  * Default value: 5120
+  * Example
+
+.. code-block:: sh
+
+  \set BROADCAST_NON_CROSS_JOIN_THRESHOLD 5120
+
+.. describe:: BROADCAST_CROSS_JOIN_THRESHOLD
+
+A threshold for cross joins. When a cross join query is executed, the whole size of broadcasted tables won't exceed this threshold.
+
+  * Configuration name: :ref:`tajo.dist-query.broadcast.cross-join.threshold-kb`
+  * Property value: Integer
+  * Unit: KB
+  * Default value: 1024
+  * Example
+
+.. code-block:: sh
+
+  \set BROADCAST_CROSS_JOIN_THRESHOLD 1024
+
+.. warning::
+  In Tajo, the broadcast join is only the way to perform cross joins. Since the cross join is a very expensive operation, this value need to be tuned carefully.
+
+.. describe:: JOIN_TASK_INPUT_SIZE
+
+The repartition join is executed in two stages. When a join query is executed with the repartition join, this value indicates the amount of input data processed by each task at the second stage.
+As a result, it determines the degree of the parallel processing of the join query.
+
+  * Configuration name: :ref:`tajo.dist-query.join.task-volume-mb`

+  * Unit: MB
+  * Default value: 64
+  * Example
+
+.. code-block:: sh
+
+  \set JOIN_TASK_INPUT_SIZE 64
+
+.. describe:: JOIN_PER_SHUFFLE_SIZE
+
+The repartition join is executed in two stages. When a join query is executed with the repartition join,
+this value indicates the output size of each task at the first stage, which determines the number of partitions to be shuffled between two stages.
+
+  * Configuration name: :ref:`tajo.dist-query.join.partition-volume-mb`
+  * Property value: Integer
+  * Unit: MB
+  * Default value: 128
+  * Example
+
+.. code-block:: sh
+
+  \set JOIN_PER_SHUFFLE_SIZE 128
+
+.. describe:: HASH_JOIN_SIZE_LIMIT
+
+This value provides the criterion to decide the algorithm to perform a join in a task.
+If the input data is smaller than this value, join is performed with the in-memory hash join.
+Otherwise, the sort-merge join is used.
+
+  * Configuration name: :ref:`tajo.executor.join.common.in-memory-hash-threshold-mb`
+  * Property value: Integer

+  * Default value: 64
+  * Example
+
+.. code-block:: sh
+
+  \set HASH_JOIN_SIZE_LIMIT 64
+
+.. warning::
+  This value is the size of the input stored on file systems. So, when the input data is loaded into JVM heap,
+  its actual size is usually much larger than the configured value, which means that too large threshold can cause unexpected OutOfMemory errors.
+  This value should be tuned carefully.
+
+.. describe:: INNER_HASH_JOIN_SIZE_LIMIT
+
+This value provides the criterion to decide the algorithm to perform an inner join in a task.
+If the input data is smaller than this value, the inner join is performed with the in-memory hash join.

+
+.. code-block:: sh
+
+  \set SORT_LIST_SIZE 100000
+
+.. describe:: GROUPBY_MULTI_LEVEL_ENABLED
+
+A flag to enable the multi-level algorithm for distinct aggregation. If this value is set, 3-phase aggregation algorithm is used.
+Otherwise, 2-phase aggregation algorithm is used.
+
+  * Configuration name: :ref:`tajo.dist-query.groupby.multi-level-aggr`
+  * Property value: Boolean
+  * Default value: true
+  * Example
+
+.. code-block:: sh
+
+  \set GROUPBY_MULTI_LEVEL_ENABLED true
+
+.. describe:: GROUPBY_PER_SHUFFLE_SIZE
+
+The aggregation is executed in two stages. When an aggregation query is executed,
+this value indicates the output size of each task at the first stage, which determines the number of partitions to be shuffled between two stages.
+
+  * Configuration name: :ref:`tajo.dist-query.groupby.partition-volume-mb`
+  * Property value: Integer
+  * Unit: MB
+  * Default value: 256
+  * Example
+
+.. code-block:: sh
+
+  \set GROUPBY_PER_SHUFFLE_SIZE 256

+.. describe:: GROUPBY_TASK_INPUT_SIZE
+
+The aggregation operation is executed in two stages. When an aggregation query is executed, this value indicates the amount of input data processed by each task at the second stage.
+As a result, it determines the degree of the parallel processing of the aggregation query.
+
+  * Configuration name: :ref:`tajo.dist-query.groupby.task-volume-mb`

+  \set GROUPBY_TASK_INPUT_SIZE 64
+
+.. describe:: HASH_GROUPBY_SIZE_LIMIT
+
+This value provides the criterion to decide the algorithm to perform an aggregation in a task.
+If the input data is smaller than this value, the aggregation is performed with the in-memory hash aggregation.
+Otherwise, the sort-based aggregation is used.
+
+  * Configuration name: :ref:`tajo.executor.groupby.in-memory-hash-threshold-mb`
+  * Property value: Integer
+  * Unit: MB
+  * Default value: 64
+  * Example
+
+.. code-block:: sh
+
+  \set HASH_GROUPBY_SIZE_LIMIT 64
+
+.. warning::
+  This value is the size of the input stored on file systems. So, when the input data is loaded into JVM heap,
+  its actual size is usually much larger than the configured value, which means that too large threshold can cause unexpected OutOfMemory errors.
+  This value should be tuned carefully.
+
+.. describe:: AGG_HASH_TABLE_SIZE
+
+The initial size of hash table for in-memory aggregation.
+
+  * Configuration name: :ref:`tajo.executor.aggregate.hash-table.size`

+  * Example
+
+.. code-block:: sh
+
+  \set AGG_HASH_TABLE_SIZE 10000
+
+.. describe:: TIMEZONE
+
+Refer to :doc:`/time_zone`.
+
+  * Configuration name: :ref:`tajo.timezone`
+  * Property value: Time zone id
+  * Default value: Default time zone of JVM
+  * Example
+
+.. code-block:: sh
+
+  \set TIMEZONE GMT+9
+
+.. describe:: DATE_ORDER
+
+Date order specification.
+
+  * Configuration name: :ref:`tajo.datetime.date-order`
+  * Property value: One of YMD, DMY, MDY.
+  * Default value: YMD
+  * Example
+
+.. code-block:: sh
+
+  \set DATE_ORDER YMD
+
+.. describe:: PARTITION_NO_RESULT_OVERWRITE_ENABLED
+
+If this value is true, a partitioned table is overwritten even if a subquery leads to no result. Otherwise, the table data will be kept if there is no result.
+
+  * Configuration name: :ref:`tajo.partition.overwrite.even-if-no-result`
+  * Property value: Boolean
+  * Default value: false
+  * Example
+
+.. code-block:: sh
+
+  \set PARTITION_NO_RESULT_OVERWRITE_ENABLED false
+
+.. describe:: TABLE_PARTITION_PER_SHUFFLE_SIZE
+
+In Tajo, storing a partition table is executed in two stages.
+This value indicates the output size of a task of the former stage, which determines the number of partitions to be shuffled between two stages.
+
+  * Configuration name: :ref:`tajo.dist-query.table-partition.task-volume-mb`
+  * Property value: Integer
+  * Unit: MB
+  * Default value: 256
+  * Example
+
+.. code-block:: sh
+
+  \set TABLE_PARTITION_PER_SHUFFLE_SIZE 256
+
+.. describe:: ARITHABORT
+
+A flag to indicate how to handle the errors caused by invalid arithmetic operations. If true, a running query will be terminated with an overflow or a divide-by-zero.
+
+  * Configuration name: :ref:`tajo.behavior.arithmetic-abort`
+  * Property value: Boolean
+  * Default value: false
+  * Example
+
+.. code-block:: sh
+
+  \set ARITHABORT false
+
+.. describe:: MAX_OUTPUT_FILE_SIZE
