Configuring Business Rules Deployment
Configuring Business Rules Deployment¶
The Business Rules Manager derives business rules from the rule templates within template groups. Each rule template has a UUID(Universally Unique Identifier) for the purpose of uniquely identifying it. When you configure a Streaming Integrator node to use a specific rule template, Siddhi applications deployed in the node are derived from the business rules created from that rule template.
To configure a Streaming Integrator node to use specific rules templates, follow the steps below:
deployment_configs:section, provide the URL(s) of the Streaming Integrator node(s) in which you want to deploy Siddhi applications. The required format is
deployment_configs: - <NODE1_HOST_NAME>:<NODE1_PORT> <NODE2_HOST_NAME>:<NODE2_PORT>
deployment_configs: - localhost:9090 10.100.4.140:9090
List down the UUIDs of required rule templates under each node. As a result, Siddhi applications are created out of the business rules that are derived from these templates for the required nodes.
deployment_configs: - <NODE1_HOST_NAME>:<NODE1_PORT>: - ruleTemplate1_UUID - ruleTemplate2_UUID - ruleTemplate3_UUID
deployment_configs: - localhost:9090: - sweet-production-kpi-analysis - stock-exchange-input - stock-exchange-output
If required, you can enter a specific rule template under multiple nodes as shown below. Before doing so, ensure the you have selected Many for the Instance Count field of the template. For more information, see Creating a Business Rules Template.
yaml deployment_configs: - <NODE1_HOST_NAME>:<NODE1_PORT>: - ruleTemplate1_UUID - ruleTemplate2_UUID - ruleTemplate3_UUID <NODE2_HOST_NAME>:<NODE2_PORT>: - ruleTemplate1_UUID - ruleTemplate3_UUID <NODE3_HOST_NAME>:<NODE3_PORT>: - ruleTemplate2_UUID - ruleTemplate3_UUID - ruleTemplate4_UUID
yaml deployment_configs: - localhost:9090: - sweet-production-kpi-analysis - stock-exchange-input - stock-exchange-output 10.100.40.169:9090: - identifying-continuous-production-decrease - sweet-production-kpi-analysis
In the above example, the
sweet-production-kpi-analysisUUID is configured under two Streaming Integrator nodes. Therefore, if you derive a business rule from the
sweet-production-kpi-analysistemplate, the Siddhi applications created from it are deployed in both the nodes.
Specify the username and password that are common for all the Streaming Integrator nodes.

The complete deployment configuration for Business Rules looks as follows.
