Summary: PR https://github.com/facebook/rocksdb/issues/5298 subtly changed how read options are applied to the index block during a Get, MultiGet, or iteration. Earlier, only the read_tier option applied to the index block read; since PR https://github.com/facebook/rocksdb/issues/5298, fill_cache and verify_checksums also have an effect. This patch restores the earlier behavior to prevent surprise memory increases for clients due to the index block not being cached.
