  • I have checked the existing issues.

Is your feature request related to a problem?

Allow user to create bloom filter on the leading column, or columns of clustering key.    So that we can have better performance for lookups.

The bloom filter could put a burden on meta data size, but, we should be able to lazy load the bloom filter.

Describe the feature you'd like

CREATE TABLE T ... CLUSTER BY (a, b, c) WITH BLOOMFILTER ON (a, b)

Or some similar syntax.

Describe implementation you've considered
