We can reduce the number of HMS calls by caching the table schema in the table properties. In `HiveIcebergSerDe.initialize()`, this results in skipping the HMS calls in all Tez workers as well as during the query optimisation steps. In the `testJoinTable()` unit test, this results in a 40% reduction in schema-related HMS calls (10 -> 6). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
