[GitHub] [druid] Aka-shi opened a new issue #9756: LATEST(expr, maxBytes) doesn't work on columns ingested as stringLast.
Aka-shi opened a new issue #9756:
URL: https://github.com/apache/druid/issues/9756
### Description
I have ingested few columns using stringLast aggregator, which stores the data as pair of time and value. I got to know that the idea is to use the same aggregator on both ingestion and query sides. But the LATEST(expr, maxBytes) doesn't work on columns stored as stringLast.
### Affected Version
Version - 0.17.0

Thanks for the report. I think what we'll need to do is update the signature of the EarliestLatestSqlAggFunction so it accepts either STRING or OTHER (which stringLast should show up as) for its string form, and then add a test to make sure it works.
