Summary: Reduce number of index lookups for same table in IndexWhereTaskDispatcher Key: HIVE-16746 URL: https://issues.apache.org/jira/browse/HIVE-16746 Project: Hive Issue Type: Bug Reporter: Rajesh Balamohan Priority: Minor {{IndexWhereTaskDispatcher}} is used when {{hive.optimize.index.filter=true}}. It lists all indices for the table and depending on the query complexity, this ends up being in the hotpath. For e.g, Q14 explain plan takes 180-200 seconds and this index querying multiple times for same tables take up 30-40 seconds. This function was invoked around 24000 times for same set of tables. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
