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.
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.
