Configuration Options

Location of config options

All config options from Reference of config options can be provided either in:

Option Description

Option	Description
environment variables	set via either `export key=val` or `--env` settings when used for docker.
`conf/apoc.conf`	located in the same folder as `neo4j.conf`

environment variables

set via either export key=val or --env settings when used for docker.

conf/apoc.conf

located in the same folder as neo4j.conf

The order of this table matches their config option precedence. E.g. any env setting will override options set in apoc.conf.

APOC Extended internally relies on Apache commons-config for resolving config settings. The meta-configuration is located in src/main/resources/apoc-config.xml.
