Hi Peter > The REST interface is waiting for the TX to be finished
I'm not sure I understand this statement. Isn't each individual REST call its own transaction? Thus, what is it waiting for? -- Tatham -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Peter Neubauer Sent: Thursday, 22 September 2011 10:07 PM To: Neo4j user discussions Subject: Re: [Neo4j] Turning Off or Configuring log rotation Romiko, I would suggest to do the TX log config via Gremlin for the time being, so you can resolve it via scripting. For the exposure of the Tx log rotate size as a configuration property (there are logs for every XA resource participating in a transaction), please raise an issue at https://github.com/neo4j/community/issues - good input! For the flushing to disk, we will merge a Deferred Write feature back into master soonish (after 1.5) which lets the OS decide when to flush, if you can stand the risk of a lost flush if things go down. The REST interface is waiting for the TX to be finished, which is why it is slowing down when you have big flushes. See https://github.com/neo4j/community/issues/18 for the ticket on this :) Would that be ok?
