Jesus Camacho Rodriguez commented on HIVE-11726: ------------------------------------------------ [~hsubramaniyan], last version of the patch removed part concerning OR/AND predicates transformation into IN (which you already covered in HIVE-11634). Thus, this patch will enable pushing the IN predicates directly to the metastore. Could you take a look? Thanks > Pushed IN predicates to the metastore > ------------------------------------- > > Key: HIVE-11726 > URL: https://issues.apache.org/jira/browse/HIVE-11726 > Project: Hive > Issue Type: Bug > Affects Versions: 2.0.0 > Reporter: Jesus Camacho Rodriguez > Assignee: Jesus Camacho Rodriguez > Attachments: HIVE-11726.01.patch, HIVE-11726.patch > > > The PointLookupOptimizer can turn off some of the optimizations due to its > use of tuple IN() clauses. > HIVE-11573 introduced the extraction of sub-clauses that could be pushed down > till the TableScan operators, though they wouldn't be pushed down to the > metastore. > In this issue, we tackle this problem by extending the filter parser of the > metastore to support IN clauses, including multiple columns. This allows to > push those additional predicates down throw directSQL to the metastore. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
