It is the default heap size for the Sun JVM, so I guess 64MB max. The documents are rather large, but if you manage to index 100,000 docs, there seems to be some problem with Solr.
The documents are not held in memory until a commit occurs (just some tracking info), so I'm not sure that that is the appropriate conclusion. Lucene keeps a few documents in memory (maxBufferedDocs--you could lower this setting), and if your documents are large, this could use a higher maximum amount of memory than in my case. Solr does keep all uniqueIds in memory until commit.
What would be the recommended heap size for Solr?
That is difficult to answer, since it depends on so many factors. 64 megs seems on the rather low end. Remember that you aren't just trying to avoid OOM errors--more memory means bigger caches and increased query performance. -Mike
