JDK: 1.8 Neo4j: 2.1.5 - Embedded and then stand-alone to test the data I'm using a program to insert a large amount of data to Neo4j. Because of memory limitations and sped limitations I usually have to do this in a few batches using BatchInserter (separate commands, long after the database has shut down -- not multiple threads). I'm getting things like this:
START x=node:main(id = "Medtr2125s0010") MATCH (x)-[:EXPRESSED]-(y) WITH x,y MATCH (y)-[:EXPRESSED]-(g) RETURN x.id,y.id,g.id Results here (copy and paste from the Web Console wasn't pretty so this is by hand): x.id: Medtr2125s0010 y.id: Nodule g.id: PAC:26323170 Returned 1 row in 110 ms Which doesn't make sense to me, not only should there be over 20,000 entries, even if it is finding just this one it should find the same x.id where g.id is. I've had no trouble doing multiple BatchInserter calls before, but have had lots of trouble with the 2.1.x line, I believe it is related to the RelationshipGroupStore, which was causing a massive slowdown (see my StackOverflow question here: http://stackoverflow.com/questions/26451609/relationshipgroupstore-mapped-memory-setting-for-batchinserter ). I plan on trying only 1 BatchInserter incarnation tonight and running it to see if it finishes properly and will report back. But this seems like a bug. Any advice on speeding up when RelationshipGroupStore slows down during the insert would also be greatly appreciated.
