atris opened a new pull request #1049: LUCENE-9074: Slice Allocation Circuit Breakers in IndexSearcher
URL: https://github.com/apache/lucene-solr/pull/1049
 
 
   This commit introduces accounting for the queue length of the ExecutorService
   being used to perform concurrent search when allocating slices for an
   IndexSearcher. This commit also introduces an abstraction to define
   custom parameters for sealing bulkheads under heavy node stress
   to allow better predictable behaviour of latencies under varying stress
