Running Neo4j purely in memory without any persistence

Question

I don\'t want to persist any data but still want to use Neo4j for it\'s graph traversal and algorithm capabilities. In an embedded database, I\'ve configured cache_typ

Answer 1

How many changes do you group in each transaction? You should try to group up to thousands of changes in each transaction since committing a transaction forces the logical log to disk.

However, in your case you could instead begin your transactions with:

db.tx().unforced().begin();

Instead of:

db.beginTx();

Which makes that transaction not wait for the logical log to force to disk and makes small transactions much faster, but a power outage could have you lose the last couple of seconds of data potentially.

The tx() method sits on GraphDatabaseAPI, which for example EmbeddedGraphDatabase implements.
