HTAP is here! It seems like these hybrid databases are slowly gaining adoption which is really cool to see.

The most interesting part of this is the improvements to transaction handling that it seems they've made in https://github.com/alibaba/AliSQL/blob/master/wiki/duckdb/du... (its also a good high level breakdown of MySQL internals too). Ensuring that the sync between the primary tables and the analytical ones are fast and most importantly, transactional, is awesome to see.

I don't think this is meaningfully HTAP, it's gluing together two completely different databases under a single interface. As far as I can tell, it doesn't provide transactional or consistency guarantees different than what you'd get with something like Materialize.

This isn't new either, people have been building OLAP storage engines into MySQL/Postgres for years, e.g., pg_ducklake and timescale.
