Apache Druid

Following the stacktrace
```at org.apache.druid.segment.ColumnProcessors.makeProcessorInternal(ColumnProcessors.java:292) ~[druid-processing-26.0.0.jar:26.0.0]```
Seems that <https://github.com/apache/druid/blame/master/processing/src/main/java/org/apache/druid/segment/ColumnProcessors.java#L292|ColumnProcessors:292> is indeed not aware of ARRAYs

thanks for the report, i’ll have a look

btw confirmed this was a mistake on my part that caused this bug, i have a fix underway

Thanks for letting me know Clint. We'll try that again on the next release (we stopped compaction temporarily, not a big deal in this case)

cool. this stuff is still pretty new, i’m pretty excited about it but there are definitely some rough edges, mostly around arrays which i hope to have resolved by the next release, thanks for trying it out :+1:

It's all understandable. The value of this feature is huge, from proper schema discovery to supporting the new types in all aspects of Druid. Definitely worth the effort. Keep it up.

Coming back to this just to say that compaction now works with v27..
