In addition to the features common to every database addon, Scalingo includes several features that are specific to our Scalingo for OpenSearch® offers.

The following table lists these features, with distinguishing values for each class of service. A short description of each feature is also available after the table.

Plugins

Scalingo for OpenSearch® addons includes several plugins that add features and capabilities to the core platform. We also add a few additional plugins. They are all available with each addon and don’t require any extra work to be enabled.

Please refer to the Using Plugins page for an exhaustive list of available plugins.

High Availability

Starter plans are running on a single node, without any redundancy or high availability mechanism. Consequently, we don’t consider them to be highly available. This translates into a lower Service Level Agreement.

Business plans, on their side, include a fully-managed cluster made of:

• Three (3) OpenSearch® nodes that are all cluster-manager-eligible, data, ingest and coordinating nodes.

  Node Type	Description
  cluster-manager	Manages the overall operation of a cluster and keeps track of the cluster state.
  cluster-manager-eligible	Elects one node among them as the cluster manager node through a voting process.
  data	Stores and searches data. Performs all data-related operations on local shards. These are the worker nodes of the cluster.
  ingest	Pre-processes data before storing it in the cluster. Runs an ingest pipeline that transforms the data before adding it to an index.
  coordinating	Delegates client requests to the shards on the data nodes, collects and aggregates the results into one final result, and sends this result back to the client.

• Two (2) HAProxy® (one active and one standby) as entrypoint to your cluster private network.

• Encrypted communications between all nodes of the cluster.

The following schema describes the cluster we setup and maintain for each Business plan:

Choosing such a plan drastically lowers the risk of unavailability, be it during a maintenance operation (database upgrade, for example) or because of a platform issue.
