   > Are you sure an index is needed? The query seems to already filter by job 
type and status, which reduces the scanned objects significantly, I am not sure 
the index overhead is worth it as the table is quite large already as is 
(largest across our clusters)
   > 
   > Can you provide benchmarks of query time improvement? And table size 
change?
   
   Fair questions, I'll move this PR back into "draft" status for the time 
being. Hopefully I'll have some time to revisit and provide thorough 
performance comparison metrics introduced by this PR.
