---------------------------------------
Summary: Allow IndexWriter to write a single DWPT to disk
Key: LUCENE-8068
URL: https://issues.apache.org/jira/browse/LUCENE-8068
Project: Lucene - Core
Issue Type: Improvement
Reporter: Simon Willnauer
Fix For: master (8.0), 7.2
Today we IW can only flush a DWPT to disk if an external resource calls flush()
or refreshes a NRT reader or if a DWPT is selected as flush pending. Yet, the
latter has the problem that it always ties up an indexing thread and if flush /
NRT refresh is called a whole bunch of indexing threads is tied up. If IW could
offer a simple `flushNextBuffer()` method that synchronously flushes the next
pending or biggest active buffer to disk memory could be controlled in a more
fine granular fashion from outside of the IW. This is for instance useful if
more than one IW (shards) must be maintained in a single JVM / system.
