Using other useful methods

There are a few other procedures that are useful when we are manipulating graphs. One of the most widely used procedures in this regard is apoc.periodic.iterate. Before the CALL subquery capability was added to Cypher, this was the only way to manipulate a graph in a batch manner.

Please note that this syntax is provided by the APOC documentation (https://neo4j.com/labs/apoc/4.4/overview/apoc.periodic/apoc.periodic.iterate/). You can visit that link for the latest syntax. The syntax of this procedure looks like this:

apoc.periodic.iterate(cypherIterate :: STRING?, cypherAction :: STRING?, config :: MAP?) :: (batches :: INTEGER?, total :: INTEGER?, timeTaken :: INTEGER?, committedOperations :: INTEGER?, failedOperations :: INTEGER?, failedBatches :: INTEGER?, retries :: INTEGER?, errorMessages :: MAP?, batch :: MAP?, operations :: MAP?, wasTerminated :: BOOLEAN?, failedParams :: MAP?, updateStatistics :: MAP?)

This procedure takes two Cypher strings...
