Using the Hudi File Format

Impala supports Read Optimized Queries on Hudi tables as an experimental feature. Read Optimized Queries treat the latest table snapshot as the commit or compaction action, expose only base/columnar files in latest file slices, and guarantee the same columnar query performance as a non-Hudi columnar table.
