ASF GitHub Bot commented on FLINK-5752: --------------------------------------- Github user ramkrish86 commented on the issue: https://github.com/apache/flink/pull/3760 @tonycox Thanks for the comment? Just curious. Any reason for the repush - is it for checking the test failures again? > Support push down projections for HBaseTableSource > -------------------------------------------------- > > Key: FLINK-5752 > URL: https://issues.apache.org/jira/browse/FLINK-5752 > Project: Flink > Issue Type: Sub-task > Components: Table API & SQL > Reporter: ramkrishna.s.vasudevan > Assignee: ramkrishna.s.vasudevan > > This is after the discussion to create NestedProjectableTableSource. > Currently we support nested schema for the non-relational type of DBs like > HBase. > But this does not allow push down projection. This JIRA is to implement that. > Once FLINK-5698 is implemented then we should be making use of the feature to > push down the projections for a nested table. So in case of HBase if we have > {f1:{a, b}, f2:{c, d}} as the nested structure then if we have a scan query > that needs to select f2.c - then we should be specifically able to project > only that column 'c' under 'f2'. FLINK-5698 plans to add a new API for such > projections and HBaseTableSource should make use of that API to do the > projection. > [~fhueske], [~tonycox], [~jark] -- This message was sent by Atlassian JIRA (v6.3.15#6346)
