@awxxxxxx Since row access policy is still experimental, please help confirm whether we should keep it here or remove it and adjust wording?
Added a new overview section describing TiDB Cloud Data Pipeline replication from TiDB Cloud to TiDB Cloud Lake. It explains the full snapshot plus incremental CDC flow, common use cases, and the external-stage dependency and plan availability restrictions.
