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 one of the following rules:

  • 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.
  • A workload routing rule that routes incoming client connections to the specified subcluster. To view existing workload routing rules, see WORKLOAD_ROUTING_RULES.

Syntax

CREATE ROUTING RULE
{
    rule_name ROUTE 'address_range' TO group_name |
    ROUTE WORKLOAD workload_name TO SUBCLUSTER subcluster_name [,...]
}

Arguments

rule_name
A name for the load balancing routing rule.
address_range
An IPv4 or IPv6 address range in CIDR format, the address range of client connections that this rule applies to.
group_name
The name of the load balance group to handle the client connections from the address range. You create this group with CREATE LOAD BALANCE GROUP.
workload_name
The name of the workload.
subcluster_name
A list of subclusters to route client connections to.

Examples

The following example creates a routing rule that routes all client connections from 192.168.1.0 to 192.168.1.255 to a load balance group named internal_clients:

=> CREATE ROUTING RULE internal_clients ROUTE '192.168.1.0/24' TO internal_clients;
CREATE ROUTING RULE

The following example creates a routing rule that routes analytics workloads to subclusters sc_analytics and sc_analytics_2. For details, see Workload routing.

=> CREATE ROUTING RULE ROUTE WORKLOAD analytics TO SUBCLUSTER sc_analytics, sc_analytics_2;
