hey @BentsiLeviav , thanks so much for opening this PR up! that incremental strategies table lists adapters supported in dbt cloud's latest release track. this is definitely something we haven't made clear in the docs and we should! as a result, i've created pr to add that clarity #6922

in terms of dbt-clickhouse incremental strategy, we recommend that you update the clickhouse configuration page so it's clear and aligns with the new message in PR #6922

i'll go ahead and close this pr out and please let me know if you have any questions! looking forward to future contributions and thank you again!
