I am using Noe4j 4.4.5 and streaming big data from Spark to Neo4j. I have streamed around 36 million addresses belonging to a blockchain as nodes with no problems. Now, I'm trying to connect the addresses that transacted with each other. The data is ...

I have deleted all the nodes and relationships in my database. However, I still can see that so much space is being taken. I found this guide in the neo4j website, but it doesn't seem to work for the community edition. When I type neo4j-admin in my s...

@giuseppe_villan Thank you for taking the time to look into this issue. I tried to install both apoc-4.4.0.3-all.jar and apoc-mongodb-dependencies-4.4.0.3.jar, and I removed apoc-4.4.0.3-core.jar. I still experience the same problem. When I deleted ...
