we've run into a weird problem with memory consumption in our cluster setup.
Important note: all described problem is only specific to the cluster, when we run all same setup but with a single node (more hefty, though), the problem does n...
we have a simple cluster consisting of only 3 Cores.
On intensive WRITE operations, we observe significant CPU load on only one of the nodes, which is Leader. Which is OK I guess since only a Leader receives writes and communicates them to the...
I need to form a dynamic query, using Filter/Filters in neo4j-ogm. The simplified version of the query may look like this:
(A and B and C)
(D or E) and not (F or J)
(H or I) and not (G or K)
So I've wrapped the code into explicit transaction of type READ-ONLY, and looks like it helped - a few nodes now are being loaded instead of only one, and the load is smaller.
@dana.canzano Thanks a lot for your help!
Thank you for the response.
We are using 4.0 version and connect using neo4j:// url.
For the querying method, we use the OGM's Session:
sessionFactory.openSession().query(DataType.class, cypher, parameters)
