I'm having a problem with Neo4j. I have 3 machines and need the three servers are always consistent. The problem is that at some point the slave does not have the update of the master. The update period can take up to several minutes (odd).
What differs from the standard in my configuration is:
ha.tx_push_factor = 2
ha.com_chunk_size = 10M
Does anyone know if you can upgrade the three servers at the same time? How to ensure database consistency? I'm using version 2.2.1.
All help is welcome.
thank you
