This repository was created for a very old ClickHouse Playground, which I successfully deleted and replaced with my new ClickHouse Playground in October 2020.
I deleted it and replaced it with my new Playground, because it was supported by irrelevant people and my bug reports were never fixed: https://github.com/ClickHouse/clickhouse-playground/issues?q=is%3Aissue+is%3Aclosed+author%3Aalexey-milovidov
The new Playground is available here: https://play.clickhouse.com/play?user=play
All issues will be closed and the repository will be archived.
