Key: LUCENE-3736
URL: https://issues.apache.org/jira/browse/LUCENE-3736
Project: Lucene - Java
Issue Type: Sub-task
Components: core/index
Reporter: Uwe Schindler
Assignee: Uwe Schindler
Fix For: 4.0
ParallelReader is now atomic. We should add a sugar wrapper method to allow
synchronized composite readers (with same segment sizes) to be aligned with
MultiReaders or wrapped by Slow:
- one ParallelReader with Slow wrapped parallel readers, they only need same
maxDoc() (and deletions)
- a MultiReader containing all sub-ParallelReaders. This needs CompositeReaders
with same docStarts[]
