## Description For DistinctCount aggregation function, we can store dictIds within segment without fetching the values, and read the values from dictionary before returning the result for the segment. Performance comparison: With the data in `OfflineClusterIntegrationTest`, for query: `select distinctcountmv(DivAirports) from mytable`, latency dropped from 18ms to 6ms. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
