 ## Limitations
 
 - **Client-side CAS**: the compare-and-swap on metadata version is enforced client-side. Concurrent maintenance on the same table should be avoided (the deduplication key prevents this under normal scheduling).
-- **Cannot write delete manifests**: the compactor cannot produce new delete manifests (iceberg-go limitation). Instead, consumed delete manifests are dropped entirely when all referenced data files have been compacted.
 - **Single filer per job**: detection tries each filer address in the cluster context until one connects, but each execution job uses the single filer address recorded in its proposal.
