API Gateway Package Configuration Properties
API Gateway uses API Gateway Data Store (Elasticsearch) as its data repository. API Gateway starts the API Gateway Data Store instance, if configured, using the default configuration shipped and located at SAG_root/InternalDataStore/config/elasticsearch.yml
Note:
To run API Gateway Data Store instances in a cluster, the elasticsearch.yml file must be updated on each instance. For additional details, see https://www.elastic.co/guide/en/elasticsearch/guide/current/important-configuration-changes.html#important-configuration-changes.
Location : SAG_root/IntegrationServer/instances/IS_Instance_Name/packages/WmAPIGateway/config/resources/elasticsearch/config.properties
pg.gateway.elasticsearch.autostart
Denotes the flag to manage (start or stop) API Gateway Data Store as part of API Gateway. Set it to false if the start or stop of API Gateway Data Store is managed from outside the API Gateway.
Possible values: true, false.
Default value is true.
pg.gateway.elasticsearch.http.connectionTimeout
Denotes maximum time in milliseconds API Gateway waits for API Gateway Data Store to start and stop if autostart is set to true.
Default value is 10000.
pg.gateway.elasticsearch.config.location
Denotes the location of the config file. If you have to use a different config file, mention the location of the config file here.
Default value is SAG_root/InternalDataStore/config/elasticsearch.yml
Note: 
*If the API Gateway Data Store hostname is same as localhost, then the system automatically modifies the value of <prop key=cluster.name> in SAG_root/IntegrationServer/instances/IS_Instance_Name/packages/WmAPIGateway/​config/resources/beans/gateway-datastore.xml to cluster.name property in the elasticsearch.yml file.
*If the API Gateway Data Store hostname is same as localhost, then the system automatically modifies the port value of localhost:9340 in SAG_root/IntegrationServer/instances/IS_Instance_Name/packages/WmAPIGateway/​config/resources/beans/gateway-datastore.xml to transport.tcp.port property in the elasticsearch.yml file.
*Ensure that the cluster.name and transport.tcp.port properties are in synchronization if you encounter any errors.
