Software AG Products 10.11 | Administrating API Gateway | Performance Tuning and Scaling | Scaling | Scaling up API Data Store

To scale up API Data Store

1. Install API Data Store or Elasticsearch in a new node.

2. Configure the required heap size. For information on increasing heap size, see Changing the JVM Heap Size to Tune API Gateway Performance.

3. In the Elasticsearch.yml file of the new node, modify the following:

Set the value of the node.master to false if the node is not a master node; and set it to true, if the node is a master node.

Set the value of the node.data to true

Specify the value of the path.repo variable same as the value in other nodes.

Specify the names of the nodes in the discovery.seed.hosts variable, in the following format:

host_name:port

For example,

discovery.seed_hosts: ["node1:9340","node2:9340","noden":"9340"]

The node names must be same as the list of nodes provided in the cluster.initial_master_nodes variable.

Save the configurations.

Start the API Data Store or Elasticsearch.

The API Data Store node is added and scaled up.
