Cluster management and Elasticsearch

Manage clusters and add nodes to relieve memory and capacity strain.

Add a Node to the Cluster

We can add a new node to the cluster by installing the MobileFirst Analytics Server or by running a standalone Elasticsearch instance.

If you choose the standalone Elasticsearch instance, you relieve some cluster strain for memory and capacity requirements, but you do not relieve data ingestion strain. Data reports must always go through the MobileFirst Analytics Server for preservation of data integrity and data optimization prior to going to persistent store.

We can mix and match.

The underlying Elasticsearch data store expects nodes to be homogenous, so do not mix a powerful 8-core 64 GB RAM rack system with a leftover surplus notebook in your cluster. Use similar hardware among the nodes.
