Feng Guo updated LUCENE-10280:
------------------------------
Description:
For scenes that index is sorted on the field, blocks that having continuous ids
can be a common situation. May we can handle this situation more efficiently
(only write the first id of this block).
We can just check
{code:java}
stritylysorted && (docIds[start+count-1] - docids[start] + 1) == count{code}
to see if ids are continuous, the check should be very light :)

We can just check

stritylysorted && (docIds[start+count-1] - docids[start] + 1) == count{code}
to see if ids are continuous, the check is very fast :)
