Subject [jira] [Commented] (HIVE-7575) GetTables thrift call is very slow
Date Tue, 27 Oct 2015 05:27:27 GMT


Szehon Ho commented on HIVE-7575:

Patch seems to help a lot!  I think it helps for when many tables case too, I dont know about
the case of many database.

One small question, why can't table_types be a list instead of a large string in metastoreClient.getTableMetas()
method?  The other MetastoreClient api's have arguments in list form, so it will be cleaner.
 Is it for performance reasons?

> The GetTables thrift call takes a long time when the number of table is large.
> With around 5000 tables, the call takes around 80 seconds compared to a "Show Tables"
query on the same HiveServer2 instance which takes 3-7 seconds.
