Running the tests
A Clickhouse server is required to run the integration tests. One can be started easily in a Docker container:
$ docker run --rm --name clickhouse -p 19000:9000 --ulimit nofile=262144:262144 clickhouse
$ export KLICKHOUSE_TEST_ADDR=127.0.0.1:19000
$ # export KLICKHOUSE_TEST_USER=default
$ # export KLICKHOUSE_TEST_PASSWORD=default
$ # export KLICKHOUSE_TEST_DATABASE=default
$ cargo nextest run
(running the tests simultaneously with cargo test
is currently not suported, due to loggers initializations.)

Credit
klickhouse_derive
was made by copy/paste/simplify of serde_derive
to get maximal functionality and performance at lowest time-cost. In a prototype, serde
was directly used, but this was abandoned due to lock-in of serde
's data model.
