The changelog mode is used for upstream data source that is already a changelog stream(has operation insert or delete per-row), so that Hudi can keep these operations as it is and keep good write throughput, the cdc mode is more general for all data source, Hudi itself maintains the changes so it is more costly and only COW table is supported for Flink now. -- This is an automated message from the Apache Git Service.
