This PR makes extends the SQL API to also handle joins. - Algebraic Joins are transpiled to Wayang Join Operator - Since the JoinOperator outputs a Tuple2<Record, Record>, the join is fused with a MapOperator to output <Record> - This is required to have downstream operations on joins such as projections/aggregations. With this PR merged, Wayang can now support simple and basic SPJ queries for decoupled JDBC sources and CSV data sources. -- This is an automated message from the Apache Git Service.
