---------------------------------------
Summary: Separate out PendingDeletes from ReadersAndUpdates
Key: LUCENE-8232
URL: https://issues.apache.org/jira/browse/LUCENE-8232
Project: Lucene - Core
Issue Type: Improvement
Affects Versions: 7.4, master (8.0)
Reporter: Simon Willnauer
Fix For: 7.4, master (8.0)
Today ReadersAndUpdates is tightly coupled with IW and all the handling of
pending deletes. This change decouples IW and pending deletes from
ReadersAndUpdates and allows expert users to customize how deletes are handled.
This is useful or up to a certain extend mandatory to work with soft-deletes to
allow merge policies to make the right decisions.
