> 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;
> +-------+---------------------------------------------------+
