-----------------------------------
Summary: Add project push-down capability to TestTableProvider
Key: BEAM-8365
URL: https://issues.apache.org/jira/browse/BEAM-8365
Project: Beam
Issue Type: New Feature
Components: dsl-sql
Reporter: Kirill Kozlov
Assignee: Kirill Kozlov
* Create a class extending InMemoryTable and implement a following method:
{code:java}
public PCollection<Row> buildIOReader(
PBegin begin, BeamSqlTableFilter filters, List<String> fieldNames);{code}
Which should return a `PCollection` with fields specified in `fieldNames` list.
* Add a property `push_down` to `TestTableProvider`, which should allow user
to select version of `InMemoryProvider` to use: with project push-down, with
predicate push-down (will be implemented later), both (will be implemented
later), or without (default).
