Databend is one of a few DBMS modeled directly after ClickHouse.

It currently does not approach a similar performance [1], and the RRIR motivation is dubious [2].

1. similar performance: There are some additional details here that may require Native Format to be enabled and some optimisations to be made, Clickbench does not always reflect the results in the best conditions and latest version.

2. RRIR: In fact, it is not rewritten in Rust, Databend is a different project. In addition, Databend supports the blake3 algorithm mentioned in the link much earlier. We are happy to see Clickhouse getting better.
