Hi, I found [HIVE-26221](https://issues.apache.org/jira/browse/HIVE-26221) uses the KLL float sketch as the histogram implementation. It works for range predicate selectivity. But float sketch cannot calculate NDV in an arbitrary range of rank. Do we support any Sketches that can calculate any range's NDV? -- This is an automated message from the Apache Git Service.
