Subject [jira] [Created] (DRILL-5097) Need to change the default width of the timestamp vector
Date Fri, 02 Dec 2016 10:47:58 GMT
Vitalii Diravka created DRILL-5097:
--------------------------------------

             Summary: Need to change the default width of the timestamp vector
                 Key: DRILL-5097
                 URL: https://issues.apache.org/jira/browse/DRILL-5097
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Codegen
    Affects Versions: 1.9.0
            Reporter: Vitalii Diravka
            Assignee: Vitalii Diravka
             Fix For: Future


Need to change the default width of the timestamp vector from 8 byte to 12, since timestamp
values can hold a new INT96 primitive type. 

Use case for it:
Using store.parquet.reader.int96_as_timestamp gives IOOB whereas convert_from works. 
The below query succeeds:
{code}
select c, convert_from(d, 'TIMESTAMP_IMPALA') from dfs.`/drill/testdata/parquet_timestamp/spark_generated/d3`;
{code}
The below query fails:
{code}
0: jdbc:drill:zk=10.10.100.190:5181> alter session set `store.parquet.reader.int96_as_timestamp`
= true;
