      Description

      Currently CatalogManager serves requests from its in-memory objects. However, these objects are not updated on the replicas. There are two approaches for this: one is to serve CatalogManager from the underlying tablet (accepting potential latency hits, but making the implementation simpler), another is to implement callbacks on transaction completion on replicas (like MarkDirty but called whenever writes are committed on a replica).
