Excerpt
We replicate objects with RTC guarantees, but when objects arrive, we move them in the background as large batch operations. For tables, doing so can cause problems. Because tables have internal data dependencies throughout their snapshots. If you replicate the top-level metadata and don't replicate the metadata nodes it points to, queries will actually fail. Because the engine you are using (Spark, PySpark, or whatever) cannot find the files or objects that the other objects point to.
