Zoltán Borók-Nagy updated IMPALA-10452:
---------------------------------------
Description:
It's convenient for users to create Iceberg tables with the old syntax.
It's also easier to migrate existing workloads to Iceberg because the SQL
scripts that create the table definitions don't need to change that much.
So users should be able to write the following:
{noformat}
CREATE TABLE ice_t (i int)
PARTITIONED BY (p int)
STORED AS ICEBERG;
{noformat}
Which should be equivalent to this:
{noformat}
CREATE TABLE ice_t (i int, p int)
PARTITION BY SPEC (p IDENTITY)
STORED AS ICEBERG;
{noformat}
Please note that the old-style CREATE TABLE creates IDENTITY-partitioned
tables. For other partition transforms the users must use the new, more generic
syntax.
Hive also supports the PARTITIONED BY syntax, see
