Hello Quanlong Huang, Riza Suminto, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/23536
to look at the new patch set (#10).
Change subject: IMPALA-13066: Extend SHOW CREATE TABLE to include stats and
partitions
......................................................................
IMPALA-13066: Extend SHOW CREATE TABLE to include stats and partitions
Adds a new WITH STATS option to the SHOW CREATE TABLE statement to
emit additional SQL statements for recreating table statistics and
partitions.
When specified, Impala outputs:
- Base CREATE TABLE statement.
- ALTER TABLE ... SET TBLPROPERTIES for table-level stats.
- ALTER TABLE ... SET COLUMN STATS for all non-partition columns,
restoring column stats.
- For partitioned tables:
- ALTER TABLE ... ADD PARTITION statements to recreate partitions.
- Per-partition ALTER TABLE ... PARTITION (...) SET TBLPROPERTIES
to restore partition-level stats.
Partition output is limited by the PARTITION_LIMIT query option
(default 1000). Setting PARTITION_LIMIT=0 includes all partitions and
emits a warning if the limit is exceeded.
Tests added to verify correctness of emitted statements. Default
behavior of SHOW CREATE TABLE remains unchanged for compatibility.
