[neo4j] Can graph Id be used as unique identifier

[faisala]

Hi All,

Can I safely use GraphId as a unique identifier of the node?

A particular case, when the nodes gets deleted, does neo4j try to reuse the GraphId of these deleted nodes for creating new nodes later ?

Thanks in advance
Faisal

#1 only if you don't rely on them to always point to the same node, as
#2 Neo4j actually does reuse them after deletion (configurable but if you switch it off your store-file will grow indefinitely)
