Re: [Neo4j] Retrieving large-ish groups of nodes

The more recent versions use and index for your IN query, so it will actually use an index or constraint in this case, that fix was added after 2.0.3 though. On Mon, Oct 13, 2014 at 11:33 PM, Aru Sahni wrote: > Hi, > > Disclaimer: I'm using Neo4j 2.0.3. I know that this is far from the most >

Re: [Neo4j] Retrieving large-ish groups of nodes

Hi Nigel, Thanks for your response. It's relieving to hear that this might be related to the deb package I used to install Neo4j. I will experiment with that shortly. I totally get what you're saying with the data modeling bit. In my case we have already modeled our domain (i.e., these nodes alre

Re: [Neo4j] Retrieving large-ish groups of nodes

Hi Aru Firstly, as a side note, the issue to which you link highlights a problem with the deb/rpm packages for some versions of Neo4j. The tarballs are fine and py2neo is definitely compatible with all versions from 1.8 upwards. Now to your main question Neo4j is optimised for efficient grap

Re: [Neo4j] Traversing Large (weighted) graphs: performance, data structure, indexes

Hello, I've done a lot of RDBMS performance tuning. Just a few quick thoughts. Be sure to run the queries in the shell, if you are not already doing so. How many rows are returned? Just sorting, then returning many rows, takes a long time to scroll them to output. If you are getting duplic
