Enable Triggers

By default triggers are disabled. We can enable them by setting the following property in apoc.conf:

apoc.conf

apoc.trigger.enabled=true
apoc.trigger.refresh=60000

Description
Option Key	Value	Description
apoc.trigger.enabled	true/false, default false	Enable/Disable the feature
apoc.trigger.refresh	number, default 60000	Interval in ms after which a replication check is triggered across all cluster nodes

This example assumes that we’ve first executed the apoc.trigger.install procedure described here:

CALL apoc.trigger.list();

Results
name	query	selector	params	installed	paused
"count-removals"	MATCH (c:Counter) SET c.count = c.count + size([f IN $deletedNodes WHERE id(f) 0])	{}	{}	TRUE	FALSE
