Max node/relationship ID allowed in neo4j?


I am new to neo4j. Still exploring right now. I'm curious about its limits.

I read that it uses 4 bytes for node ID and relationship ID. Doesn't that mean that the max node/relationship ID allowed is ~4B? But I also read that the limit is much higher than that.

I must have missed something here. Can someone help explain that? Thanks a lot! details the limits
