-| high.cardinality.identify.enable | true | If the parameter is true, the high cardinality
columns of the dictionary code are automatically recognized and these columns will not be
used as global dictionary encoding. If the parameter is false, all dictionary encoding columns
are used as dictionary encoding. The high cardinality column must meet the following requirements:
value of cardinality > configured value of high.cardinality. Equally, the value of cardinality
is higher than the threshold.value of cardinality/ row number x 100 > configured value
of high.cardinality.row.count.percentage. Equally, the ratio of the cardinality value to data
row number is higher than the configured percentage. Note: If SINGLE_PASS is used during data
load, then this property will be disabled.|
+| high.cardinality.identify.enable | true | If the parameter is true, the high cardinality
columns of the dictionary code are automatically recognized and these columns will not be
used as global dictionary encoding. If the parameter is false, all dictionary encoding columns
are used as dictionary encoding. The high cardinality column must meet the following requirements:
value of cardinality > configured value of high.cardinality. <b> Note: </b>
If SINGLE_PASS is used during data load, then this property will be disabled.|
 | high.cardinality.threshold | 1000000  | It is a threshold to identify high cardinality
of the columns.If the value of columns' cardinality > the configured value, then the columns
are excluded from dictionary encoding. |
-| high.cardinality.row.count.percentage | 80 | Percentage to identify whether column cardinality
is more than configured percent of total row count.Configuration value formula:Value of cardinality/
row number x 100 > configured value of high.cardinality.row.count.percentage. The value
of the parameter must be larger than 0. |
 | carbon.cutOffTimestamp | 1970-01-01 05:30:00 | Sets the start date for calculating the
timestamp. Java counts the number of milliseconds from start of "1970-01-01 00:00:00". This
property is used to customize the start of position. For example "2000-01-01 00:00:00". The
date must be in the form "carbon.timestamp.format". NOTE: The CarbonData supports data store
up to 68 years from the cut-off time defined. For example, if the cut-off time is 1970-01-01
05:30:00, then the data can be stored up to 2038-01-01 05:30:00. |
 | carbon.timegranularity | SECOND | The property used to set the data granularity level DAY,
HOUR, MINUTE, or SECOND. |
