Ah, I see. So there's a replication process similar to ClickHouse's MaterializedPostgres. Ideally, there would be functionality allowing a columnstore query to wait until all writes to the OLTP tables — up to the query's execution time — are available. This would make the system truly Postgres-native and address issues that no other system currently solves.

yep exactly. we can wait for replay LSN. So you're only reading once all writes to OLTP are complete.
