Server Configuration Parameter Reference

This section describes all server configuration guc/parameters that are available in HAWQ.

Configuration guc/parameters are located in $GPHOME/etc/hawq-site.xml. This configuration file resides on all HAWQ instances and can be modified by using the hawq config utility. You can use the same configuration file cluster-wide across both master and segments.

Note: While postgresql.conf still exists in HAWQ, any parameters defined in hawq-site.xml will overwrite configurations in postgresql.conf. For this reason, we recommend that you only use hawq-site.xml to configure your HAWQ cluster.
