Change subject: [WIP] IMPALA-3430: Runtime filter : Extend runtime filter to support Min/Max values for HDFS scans ...................................................................... [WIP] IMPALA-3430: Runtime filter : Extend runtime filter to support Min/Max values for HDFS scans This patches enables min/max filtering in which the filters are built from non-correlated subqueries that return one row and the filtering target is the scan node to be qualified by one of the subqueries. Shown below is one such query that normally gets compiled into a nested loop join. select count(*) from store_sales where ss_sales_price < (select avg(ss_wholesale_cost) from store_sales); Change-Id: I7c2bb5baad622051d1002c9c162c672d428e5446 --- M be/src/exec/nested-loop-join-builder.cc M be/src/exec/nested-loop-join-builder.h M be/src/exec/nested-loop-join-node.cc 3 files changed, 156 insertions(+), 3 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/06/17706/2 -- To view, visit http://gerrit.cloudera.org:8080/17706 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I7c2bb5baad622051d1002c9c162c672d428e5446 Gerrit-Change-Number: 17706 Gerrit-PatchSet: 2 Gerrit-Owner: Qifan Chen <qc...@cloudera.com>
