Does DataMiner AI require both Cassandra and Elastic DB to unlock all of its functionalities? Or would all of the functionalities work with just Cassandra DB alone?
Only the pattern matching feature needs Elastic. This will not work without it.
Behavioral Anomaly detection is a bit special in that regard. It will work without Elastic. However, you will need it to be able to query the datasource in Dashboards.
Hi Naveen, please find here the link of features requiring Cassandra & Elasticsearch: Data Storage Architecture – DataMiner Dojo
Naveen
Please note that we no longer recommend any production deployments with Cassandra database only; please refer to Supported system data storage architectures | DataMiner Docs .
However, you can install Elasticsearch and Cassandra in one node as the bare minimum; please see the following section at DataMiner Compute Requirements – DataMiner Dojo .
“Important: If you intend to run, e.g. DataMiner, Cassandra and Elasticsearch on a single server, the hardware requirements in the diagram below need to be added up. So, when it comes to RAM, in this case you would need a minimum of 96 GB (32 GB for DataMiner, 32 GB for Cassandra and 32 GB for Elasticsearch).”
Going back to your original question,
From my understanding AI features are referred to as ‘Advanced Analytics’ in our documentation. As Willem confirmed above, only the pattern matching feature requires Elasticsearch, and the rest works with the Cassandra database. The following links summarise features and their dependency on the relevant database.
Advanced analytics in trend graphs | DataMiner Docs
