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.
