Deleted index still showed in the SHOW TAG INDEX STATUS results

[randomJoe211]

Nebula Graph version: 2.5.0

I have an index date1_index, and I have rebuilt it once:

But even after I dropped this index, the rebuilding history is still there:

I submitted a compaction job, but the history is still there. This logic is not good. Will the rebuilding history ever be updated? I think we should clear the history of the dropped indexes.

nGQL code:

The history won't be update by design. SHOW JOBS literally show all jobs you have submitted, it should not interfere with DDL.
