How does mooncake work with std oltp workloads? Can I use Postgres with OLTP , add mooncake and expect duckdb-level of performance for OLAP queries? I know that SAP HANA has some sort of several layers of storage and automatic movement of data between them to allow for such performant OLTP/OLAP hybrid, and I think this is the holy grail for cheap/open source db. Users need OLTP first but don’t want to add Kafka + clickhouse or similar pipelines when OLAP is needed.
