Hi @ramkrish86,
I'm currently very busy getting the last changes for some bigger features
in before the feature freeze for Flink 1.3. Can't promise that I'll have time
to look at this before the release branch is forked off.
Best, Fabian
> 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.
