Contributor guide
Research direction
Start by locating the existing decoder implementations and the ClickHouse integration entry points in the Gluten repository, then read how current decoders are tested. Define the Parquet decoder's supported inputs and expected behavior before implementation; done means the new decoder works with the relevant Spark SQL execution path and has coverage for its supported cases.
