@mzitnik could you fix the tests?

@mzitnik can we start with 0.1.0 as we did for kafka connect sink? https://github.com/ClickHouse/clickhouse-kafka-connect/releases?page=4
I'm not comfortable with 1.0.0 since we might need to introduce breaking changes based on the initial feedback

@mshustov
In Kafka Connect, we started with 0.0.1 https://github.com/ClickHouse/clickhouse-kafka-connect/releases/tag/v0.0.1-alfa
Looking at this, I was thinking maybe the DataStream we use 1.0.0 And when we develop the Table API, we will use 2.0.0

[mshustov]

@mzitnik I know, 0.0.1 just looks like an alpha or beta version, which might look scary, so I'd prefer 0.1.0 to re-assure the customers

feel free to merge and publish when the version is changed to 0.1.0
