Procedures

This page provides a complete reference to the Neo4j procedures. Available procedures depend on the type of installation you have:

  • Neo4j Enterprise Edition provides a larger set of procedures than Neo4j Community Edition.

  • Cluster members have procedures that are not available in standalone mode.

To check which procedures are available in your Neo4j DBMS, use the Cypher command SHOW PROCEDURES:

Example 1. List available procedures
SHOW PROCEDURES

Some procedures can only be run by users with Admin privileges. Specifically, either the EXECUTE ADMIN PROCEDURES privilege or both the EXECUTE PROCEDURES and EXECUTE BOOSTED PROCEDURES privileges. These procedures are labeled with Admin Only.

For more information, see the EXECUTE privileges section.

Table 51. dbms.cluster.readReplicaToggle()

Description

The toggle can pause or resume read replica (deprecated in favor of dbms.cluster.secondaryReplicationDisable)

Signature

dbms.cluster.readReplicaToggle(databaseName :: STRING, pause :: BOOLEAN) :: (state :: STRING)

Mode

DBMS

Replaced by

dbms.cluster.secondaryReplicationDisable()

What is it for?

You can perform a point-in-time backup, as the backup will contain only the transactions up to the point where the transaction pulling was paused. Follow these steps to do so:

  1. Connect directly to the server hosting the database in secondary mode. (Neo4j Driver use bolt:// or use the HTTP API).

  2. Pause transaction pulling for the specified database.

  3. Back up the database, see Back up an online database.

If connected directly to a server hosting a database in secondary mode, Data Scientists can execute analysis on a specific database that is paused, the data will not unexpectedly change while performing the analysis.

This procedure can only be executed on a database that runs in a secondary role on the connected server.
