----------------------------------
Summary: COUNT(DISTINCT) should support binary field
Key: FLINK-24485
URL: https://issues.apache.org/jira/browse/FLINK-24485
Project: Flink
Issue Type: Improvement
Components: Table SQL / API
Affects Versions: 1.14.0
Reporter: Haohui Mai
Current the SQL API fails when doing {{COUNT(DISTINCT)}} on a binary field. In
our use case we store the UUID as a 16-byte binary string.
While it is possible to work around to do a base64 encoding on the string but
it should be relatively straightforward to implement the native solution to
gain the optimal speed.
