Ivan Sadikov commented on SPARK-40169:
--------------------------------------
I would like to work on it as it was my responsibility to come up with a proper
fix for the original issue :). I will sync with [~chaosun] offline and we will
come up with the strategy to address the problem properly.

> This is a follow for SPARK-39833. In

> This ticket is for permanent and thorough fix for the issue and re-enablement
> of the column index. See more details in the PR linked above.
