Dear All,
Will need your advice on the following:
Is Elastic Application better or Open Search application better in Dataminer?
Look for your advice.
Thanks,
Best Regards,
Tser Siong
Hi Tser,
As far as functionality is concerned Elastic and OpenSearch perform the same function as a dependency of DataMiner. Both allow for efficient indexing and querying of large datasets.
The main difference is that OpenSearch is an open source continuation of Elastic. As more recent versions of Elastic have changed their licensing model.
That is why DataMiner only offers support up to Elastic 6.8 which is currently end-of-life.
For OpenSearch, we support all currently released versions.
If you’re aiming to deploy a new DataMiner system soon then perhaps you could have a look at our upcoming Storage as a Service offering. Which has additional benefits regarding scaling and ease-of-use.
If the system cannot possibly be cloud connected then we recommend OpenSearch for any new deployments of DataMiner that are purely on-prem.
The support for Elastic 6.8 is maintained in DataMiner in case an existing system needs to be scaled up with additional nodes.
With Kind Regards,
Hi Tser,
OpenSearch itself can be installed on Redhat Linux.
(see https://opensearch.org/docs/latest/install-and-configure/install-opensearch/index/)
Regarding testing, our internal system with OpenSearch make use of Ubuntu. As there is a wide variety of Linux distributions out in the field it is not feasible for us to test all of them. Here we can only trust the claims that OpenSearch makes that it runs the same on every distribution that it supports.
Thanks 🙂
So OpenSearch can be installed on Redhat Linux version 7 and 8?
Once the Linux O/S installation is completed, what are the steps to proceed with the Open Search Application installation.
Do note the server is not connected to internet, can the Open Search Application be installed offline?
Hi Tser,
In our own documentation we lay out a possible installation path using Debian. (https://docs.dataminer.services/user-guide/Advanced_Functionality/Databases/Indexing_database/OpenSearch_Database/Installing_OpenSearch_database.html?q=installopensearch).
For installing on RHEL it’s not possible to use Debian however, here you can follow the documentation provided by OpenSearch for RPM (https://opensearch.org/docs/latest/install-and-configure/install-opensearch/rpm/).
This will allow you to install the application, once installed please do take a moment to review the Important Settings and port requirements as listed in the OpenSearch documentation. (https://opensearch.org/docs/latest/install-and-configure/install-opensearch/index/#important-settings)
Having the necessary ports open and correct key settings will help achieve optimal performance.
With OpenSearch fully installed, you can proceed with configuring DataMiner to make use of it. For this you can follow the steps in our documentation.
See step 4 under the Cassandra cluster database configuration.

Thanks Simon.
Yes, this will be for new Dataminer system, and it will be purely for on-prem.
As such, Open Search will be the only solution.
Please advise if Open Search can be installed on Redhat Linux instead of Ubuntu? And has the testing of Open Search on Redhat Linux been tested with the required Dataminer support?
