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.

This ColumnStore is very simple and just do table scans sequentially on every query. It doesn't support indexes and unique constraints. It is almost an append-only serialization file format, but with some columnar concepts.
Can tiger data be used just as a simple column store?
All I want is effectively what clickhouse does in PG. I have a single table that I need fast counts on and clickhouse can do the counts fast but I have to go through the entire sync/replication to do that.
A quick scan of TimeSeries always seemed like it was really only best setup for that and to use it another way would be a bit of a struggle.
in a way -- materialized views --
but Tiger Data is more optimized for TimeSeries data - https://www.tigerdata.com/docs/use-timescale/latest/hypercor...
I do wish too there was an embedded click house like db in Postgres
MariaDB has supported columnar tables for a bit https://mariadb.com/resources/blog/see-columnar-storage-for-...
I don't think MariaDB ColumnStore has any kind of advantage. It is just an append-only storage format with some columnar concepts.

Mariadb has a columnar engine already (though I did not use it myself) https://mariadb.com/docs/analytics/mariadb-columnstore/colum... and is mostly mysql compatible.
For about a year releases include a vector storage type, so it will be interesting to see it compared in performance with what Alibaba did.
Just wanted to plug that out. Given how often Postgres is plugged on HN, I think people ignore how versatile mariadb is.
