David Smiley commented on LUCENE-8267:
--------------------------------------
[~dweiss] I noticed the solr/CHANGES.txt entry you added recommended users
switch to "Direct" instead. I'm surprised we would recommend that....
(especially given the demise of "Memory"). Wouldn't FST50 be better? I'd like
to reword the CHANGES.txt to the following:
{noformat}
* LUCENE-8267: Memory codecs have been removed from the codebase
(MemoryPostings,
MemoryDocValues). If you used postingsFormat="Memory" switch to "FST50" as
the next best alternative,
or use the default. If you used docValuesFormat="Memory" then remove it to
get the default. (Dawid Weiss){noformat}

> Memory codecs (MemoryPostings*, MemoryDocValues*) are part of random
> selection of codecs for tests and cause occasional OOMs when a test with huge
> data is selected. We don't use those memory codecs anywhere outside of tests,
> it has been suggested to just remove them to avoid maintenance costs and OOMs
> in tests. [1]
