-----------------------------------
Summary: Early Terminating CollectorManager
Key: LUCENE-8929
URL: https://issues.apache.org/jira/browse/LUCENE-8929
Project: Lucene - Core
Issue Type: Improvement
Reporter: Atri Sharma
We should have an early terminating collector manager which accurately tracks
hits across all of its collectors and determines when there are enough hits,
allowing all the collectors to abort.
The options for the same are:
1) Shared total count : Global "scoreboard" where all collectors update their
current hit count. At the end of each document's collection, collector checks
if N > threshold, and aborts if true
2) State Reporting Collectors: Collectors report their total number of counts
collected periodically using a callback mechanism, and get a proceed or abort
decision.
1) has the overhead of synchronization in the hot path, 2) can collect
unnecessary hits before aborting.
I am planning to work on 2), unless objections
