> 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

> 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.
