Elasticsearch is the datastore for the Elastic (ELK) Stack
Launching this package follows different steps:
[Cluster mode] Creating certificates and configuring the nodes
Running Elasticsearch
Setting Elasticsearch passwords
Importing Elasticsearch index
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.
When running in DEV mode, Elasticsearch is reachable at:
http://127.0.0.1:9201/
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.
