Elasticsearch is the datastore for the Elastic (ELK) Stack

Launching

Launching this package follows different steps:

• [Cluster mode] Creating certificates and configuring the nodes

• Running Elasticsearch

• Setting Elasticsearch passwords

• Importing Elasticsearch index

Importing

To initialize the index mapping in Elasticsearch, a helper container is launched to import a config file to Elasticsearch. The config importer looks for a field named fhir-enrich-report.json in <path to project packages>/analytics-datastore-elastic-search/importer.

The file fhir-enrich-report.json will contain the mapping of the index fhir-enrich-reports.

Elasticsearch will create a dynamic mapping for the incoming data if we don't specify one, this dynamic mapping may cause issues when we start sending the data as it doesn't necessarily conform 100% to the data types that we're expecting when querying the data out of Elasticsearch again.

Therefore, the mapping should be initialized in Elasticsearch using the config importer.

The file fhir-enrich-report.json is just an example, the name and the mapping can be overridden.

Running in Dev Mode

When running in DEV mode, Elasticsearch is reachable at:

http://127.0.0.1:9201/

Elasticsearch Backups

For detailed steps about creating backups see: Snapshot filesystem repository docs.

Elasticsearch offers the functionality to save a backup in different ways, for further understanding, you can use this link: Register a snapshot repository docs.
