Michael McCandless commented on LUCENE-1329:
--------------------------------------------
Jason, have you run any scale tests (w/ many threads) to confirm whether
volatile is faster than using synchronized, for this case? I'm especially
curious on what happens with JRE 1.4, since with this patch it is now
synchronized and volatile.
I think we should, at least in addition but perhaps instead, create a way to
open a read-only IndexReader. This way no synchronization nor volatile would
be necessary when accessing deletedDocs.
> Remove synchronization in SegmentReader.isDeleted
