---------------------------------------
Summary: SHOW CREATE TABLE with stats and partitions
Key: IMPALA-13066
URL: https://issues.apache.org/jira/browse/IMPALA-13066
Project: IMPALA
Issue Type: New Feature
Components: Backend, Frontend
Reporter: Quanlong Huang
SHOW CREATE TABLE produces the statement to create the table. In practise, we
also want the column stats and partitions. It'd be helpful to add an option for
also producing the ADD PARTITION and SET COLUMN STATS statements. E.g.
{code:sql}
SHOW CREATE TABLE my_tbl WITH STATS;{code}
produces
{code:sql}
CREATE TABLE my_tbl ...;
ALTER TABLE my_tbl ADD PARTITION ...;
ALTER TABLE my_tbl PARTITION (...) SET TBLPROPERTIES('numRows'='30000',
'STATS_GENERATED_VIA_STATS_TASK'='true');
ALTER TABLE my_tbl SET COLUMN STATS c1
('numDVs'='19','numNulls'='0','maxSize'='8','avgSize'='8');
{code}
