Specify the amount of heap memory the Funnelback graph service should be generated with next time it is regenerated by the script. This effectively sets the JVM -Xmx option on the graph/neo4j process.

The format of the value is as for the JVM’s -Xmx option, i.e. a number followed by a unit, generally m for megabytes or g for gigabytes.

Note that changing this value will have no impact until the service is regenerated, it’s just specified here to avoid custom values being overwritten within the service config on upgrade etc.

Setting the key

Set this configuration key in the server configuration.

Use the configuration key editor to add or edit the neo4j.max_heap_size key, and set the value. This can be set to any valid String value.
