This module connects Table/SQL API and runtime. It is responsible for translating and optimizing a table program into a Flink pipeline. For user documentation, check the table documentation.
This README contains some development info for table planner contributors.
Unit tests verifying the JSON plan changes (e.g. Java tests in org.apache.flink.table.planner.plan.nodes.exec.stream) can regenerate all the files setting the environment variable PLAN_TEST_FORCE_OVERWRITE=true.
