Checks are failing. Will not request review until checks are succeeding. If you'd like to override that behavior, comment assign set of reviewers

I do not think this failure is related to my implementation

assign set of reviewers

[github-actions]

Assigning reviewers. If you would like to opt out of this review, comment assign to next reviewer:

R: @Abacn for label java.
R: @damondouglas for label io.

Available commands:

• stop reviewer notifications - opt out of the automated review tooling
• remind me after tests pass - tag the comment author after tests pass
• waiting on author - shift the attention set back to the author (any comment or push by the author will return the attention set to the reviewers)

The PR bot will only process comments in the main thread (not review comments).

Thanks, this looks good to me. Had a comment about documentaion

[Abacn]

This is javadoc. The statement "Adding support ..." sounds like an announcement and consider moving it to CHANGES.md

For here, consider phrasing like "Low cardinality hint is supported through LowCardinality DataType in ClickHouse."

Thanks, LGTM, will merge once tests passed
