Summary: Improve BKDWriter's checksum verification
Key: LUCENE-7120
URL: https://issues.apache.org/jira/browse/LUCENE-7120
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: master, 6.1
The checksum verification only works when {{BKDWriter}} fully reads one of its
temp files, but today it opens a reader, seeks to one slice, reads that, and
closes.
But it turns out, on the full recursion from any given node in the tree, a
given file is read once, fully, so if we just share the readers, then we can
get checksum verification for these files as well.
This is a non-trivial change ... I don't plan on pushing it for 6.0.
