having an embedded column database for analytics in your traditional db is a massive win for productivity + operations simplicity.

at the moment I use PG + Tiger Data - couldn't find a mysql equivalent

so this as one.

One option is TiDB. It has support for columnar data alongside row based data. However, it is MySQL compatible, but not based on MySQL code so not quite what you asked for.

>>travem+Uj
Yes, TiDB has columnar data and also Vector support. All open source and MySQL compatible.
