11.1.3.1.1 Configuring On-Heap Limits
The on-heap memory limits for the graph server (PGX) can be configured by
updating the
systemd
configuration file for the PGX service. However,
there is a risk of losing the updates to the configuration file, the next time you
upgrade the graph server (PGX). Therefore, it is recommended that you provide the
on-heap memory configuration in a drop-in file. All directives in the drop-in file are
dynamically merged with the directives in the main configuration file
(/etc/systemd/system/pgx.service
) during the graph server (PGX)
startup.
You can perform the following steps to create a drop-in file and configure the on-heap memory size:
