I think we need to account for the case where trimmedAboveSeqNo is equal to SequenceNumbers.UNASSIGNED_SEQ_NO. Perhaps we can add a method to checkpoint called getMaxEffectiveSeqNo which is:
if (trimmedAboveSeqNo == SequenceNumbers.UNASSIGNED_SEQ_NO)
return maxSeqNo;
else
return Math.min(maxSeqNo, trimmedAboveSeqNo);

SequenceNumbers.min should handle this case:
But having an explicit method is better. I pushed 563545c.

Ah lol, I did not see that a special min method was used (I read it as Math.min).

Today we do not consider trimAboveSeqNo when calculating the translog generation of an index commit. If there is no new indexing after the primary promotion, then we won't be able to clean up the translog.

While working on the fix for #49970, I found that we do not consider trimAboveSeqNo when calculating the translog generation of an index commit. If there is no new indexing after the primary promotion, then we won't be able to clean up the translog.
