20.1.3.1.2 Configuring Off-Heap Limits

You can specify the off-heap limit by setting the max_off_heap_size field in the graph server (PGX) configuration. See Configuration Parameters for the Graph Server (PGX) Engine for more information on the max_off_heap_size parameter. Note that the off-heap limit is not guaranteed to never be exceeded because of rounding and synchronization trade-offs.
