apoc.hashing.fingerprintGraph
Function APOC Core
calculate a checksum (md5) over a the full graph. Be aware that this function does use in-memomry datastructures depending on the size of your graph.
Usage Examples
The examples in this section are based on the following sample graph:
MERGE (joe:Person {name: "Joe"})
MERGE (ryan:Person {name: "Ryan"})
MERGE (ryan)-[:FOLLOWS {since: datetime("2020-11-04")}]->(joe);
This function computes a fingerprint of the whole graph using the MD5 checksum:
RETURN apoc.hashing.fingerprintGraph() AS output;
output |
---|
"655408F901B554A8999AEF61EA6D5AE5" |
We can pass in a list of properties to exclude from the fingerprint, as shown in the following query:
RETURN apoc.hashing.fingerprintGraph(["since"]) AS output;
output |
