Question

Hi I added some additional columns to star tree index but I don t see the new column being part of the start tree index in the new segments doesn t modifications get reflected in the new segments IIRC reloads doesn t help with modifications to the star tree index correct me if I am wrong

Jackie · Answer

Yes reload cannot modify the existing star tree it can only add new star tree if no one exists yet

once the index config is applied shouldn t the new segments use the updated index config

Jackie · Answer

Yes the new segments should be able to pick up the new config

Pradeep · Answer

hmm weird I don t see it happening in the newer segments let me double check

Jackie · Answer

For realtime table the new config will only be picked up by the next consuming segment

Jackie · Answer

The current consuming segment will still use the old table config

Pradeep · Answer

I don t see it in the newer segments too I enabled this around midnight yesterday There are a lot of segments that got generated after that but I don t see it in any of those

Pradeep · Answer

Is there a scenario where a column will be skipped by star tree

Pradeep · Answer

if the cardinality of the column is more than `max leaf records` then the column wouldn t be included in the index

Jackie · Answer

No star tree should not skip any column explicitly configured

Jackie · Answer

What is the old and new star tree config

Jackie · Answer

You may search the log for `Starting building star tree with config ` which should print the star tree configs used

Pradeep · Answer

let me check that
