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?
> GetTables thrift call is very slow

> 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.
