CREATE ROUTING RULE
Creates a load balancing routing rule that directs incoming client connections from an IP address range to a group of Vertica nodes.
Creates a load balancing routing rule that directs incoming client connections from an IP address range to a group of Vertica nodes. This group of Vertica nodes is defined by a load balance group. Once you create a routing rule, any client connection originating from the rule's IP address range is redirected to one of the nodes in the load balance group if the client opts into load balancing.
Syntax
CREATE ROUTING RULE rule_name ROUTE 'address_range' TO group_name
