Apache Druid

I think this might be what you want <https://druid.apache.org/docs/latest/operations/dump-segment|https://druid.apache.org/docs/latest/operations/dump-segment>

or if not exactly, it's fairly easy to modify to add modes do what you want, <https://github.com/apache/druid/blob/master/services/src/main/java/org/apache/druid/cli/DumpSegment.java|https://github.com/apache/druid/blob/master/services/src/main/java/org/apache/druid/cli/DumpSegment.java>

Wow, thanks for that - I tried source hunting but failed to locate this file - how did you pin point this file?

Dump segment tool worked, but we got the resources to do it normally :+1:

oh heh, I kind of cheated and have been writing a bunch of the code for many years now, a lot of it around segment level query processing, and just know where things are :sweat_smile:
