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.
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.
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.
