OpenSearch database

If you choose self-hosted storage instead of the recommended Storage as a Service (STaaS) setup, OpenSearch is the recommended indexing database. This is supported from DataMiner 10.3.0/10.3.3 onwards. In earlier DataMiner versions, Elasticsearch is used, but as Elasticsearch is only supported up to version 6.8, which is no longer supported by Elastic, this is not recommended.

In a dedicated clustered storage setup, once you have configured a Cassandra-compatible database service, you need to set up the indexing database cluster to complete your setup. In a setup with storage per DMA, setting up an indexing database is not mandatory, but it is highly recommended, as otherwise you will not have access to several DataMiner features.

For more information on how to install an OpenSearch database, see Installing an OpenSearch database.

From DataMiner 10.3.0/10.3.3 onwards, you can have data offloaded to multiple OpenSearch clusters. For more information on how to configure this setup, see Configuring multiple OpenSearch clusters.

If you have a large cluster with nodes in different zones, data centers, or racks, you should configure allocation awareness.

Note

To query the OpenSearch database, you can use the ElasticVue browser extension. However, note that ElasticVue was created for ElasticSearch, so not everything may work for OpenSearch.
