-----------------------------------
Summary: fix+document+rename DiskDV to Lucene45
Key: LUCENE-5124
URL: https://issues.apache.org/jira/browse/LUCENE-5124
Project: Lucene - Core
Issue Type: New Feature
Affects Versions: 4.5
Reporter: Robert Muir
The idea is that the default implementation should not hold everything in
memory, we can have a "Memory" impl for that. I think stuff being all in heap
memory is just a relic of FieldCache.
In my benchmarking diskdv works well, and its much easier to manage (keep a
smaller heap, leave it to the OS, no OOMs etc from merging large FSTs, ...)
If someone wants to optimize by forcing everything in memory, they can then use
the usual approach (e.g. just use FileSwitchDirectory, or pick "Memory" for
even more efficient stuff).
Ill keep the issue here for a bit. If we decide to do this, ill work up file
format docs and so on. We should also fix a few things that are not great about
it (LUCENE-5122) before making it the default.
