Neo4j 5.1.0 There is no procedure with the name `apoc.cypher.mapParallel2` registered for this database instance

I'm trying to migrate to Neo4j 5.1.0

I downloaded APOC from https://github.com/neo4j/apoc/releases

In the Neo4j browser, I checked the version:

RETURN apoc.version() AS output;

"5.1.0"

Now, when I run my Cypher queries, I receive the following error:

There is no procedure with the name `apoc.cypher.mapParallel2` registered for this database instance

Looks like this procedure is not the part of APOC core anymore. Is it possible to get this somewhere else for Neo4j 5.x ?

Solution

  • Starting Neo4j 5.0, APOC has been divided into two parts Core and Extended. The apoc.cypher.mapParallel2 is part of the extended package. The error message means, that you are only using the core package. You should install the extended APOC package, by following the instructions from here.

    APOC Extended.
