It can be used as a pure open-source (Apache 2.0) alternative to TimescaleDB or as a PostgreSQL-native alternative to dedicated analytics stores like ClickHouse, when you'd like your data to stay in Postgres. δx stores the compressed columnar data in regular Postgres tables. It does not use its own storage format on disk. The advantage of this approach is that features like physical/logical replication, crash recovery, backups, and pg dump work as for any other Postgres table.

ClickBench On the ClickBench benchmark, which runs 43 analytical queries against a web analytics dataset of 100M rows × 105 columns, δx currently ranks lower than specialized analytical stores like ClickHouse and DuckDB, but it is the highest-ranking of all the systems that are storing the data in PostgreSQL. The following screenshot contains a selection of Postgres extensions/projects + ClickHouse for reference. It displays the \"combined\" metric, which is a weighted average combining hot times, cold time, load time, and storage size.
