Summary: [SQL] Implement Stateful Join
Key: BEAM-3191
URL: https://issues.apache.org/jira/browse/BEAM-3191
Project: Beam
Issue Type: Bug
Components: dsl-sql
Reporter: Anton Kedin
For binary key-joins, we probably could implement stateful join.
Things to consider:
- identify primary keys for the inputs if possible;
- otherwise buffer both collections, correctly discard collections prefixes on
timer;
