ShreelekhyaG opened a new pull request #4257:
URL: https://github.com/apache/carbondata/pull/4257
### Why is this PR needed?
Currently, whenever MV is created with average aggregate, a full refresh is
done meaning it reloads the whole MV for any newly added segments. This will
slow down the loading. With incremental data load, only the segments that are
newly added can be loaded to the MV.
### What changes were proposed in this PR?
If avg is present, rewrite the query with the sum and count of the columns
to create MV and use them to derive avg.

### Does this PR introduce any user interface change?
- No
### Is any new testcase added?
