I have reached a state where there was a piece of code which deleted the nodes without deleting the relationships of the same. Now I am frequently getting node with node id not found error. Is there a way I can delete such relationships and indexes a...
Hi! We recently switched to the latest Springboot version (well 2.4.0 since it already not the latest anymore) and tried to be ogm-free. Our app works fine but we've noticed a warning we didn't see before (I don't think it happened, but maybe we just...

After playing enough with neo4j alone, I decided to integrate it to my PHP project, and searched for drivers or whatever it is called. The only not abandoned github repository I found, the one called a partner on this forum, stopped development like ...
Hello, Was wondering if there was a way to check to see if the driver connected to the neo4j server when the driver was initialized, that way I can throw an error or panic when the application cannot connect to the server. Thanks, Matt
