The present disclosure involves systems, software, and computer implemented methods for deploying changes to key patterns in database systems. One example method includes receiving a new shared container that includes a new key pattern for a logical split table and an updated read-only-portion physical table for a logical split table. The updated read-only-portion physical table includes records that match a complement of the new key pattern. Records that match the new key pattern are identified in the read-only-portion physical table of the logical split table in a current shared container. The identified records are moved from the read-only-portion physical table in the current shared container to a writable-portion physical table in a tenant container. Records not matching the new key pattern are deleted from the writable-portion physical table of the logical split table in the tenant container.
