Subject [jira] [Commented] (HIVE-7575) GetTables thrift call is very slow
Date Fri, 23 Oct 2015 15:45:27 GMT

    [ https://issues.apache.org/jira/browse/HIVE-7575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14971197#comment-14971197

Navis commented on HIVE-7575:
-----------------------------

getTables() is the first call from most BI tools but it takes so much time with 100+ databases.
I think it's worth to make a dedicated API in metastore for this.

> 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.
