Deprecated and Discontinued Features
This topic lists features deprecated features in InterSystems IRIS®; it also lists any features that are discontinued or removed.
About Deprecated and Discontinued Technologies and Features
From time to time, InterSystems stops further development of a technology when newer and better options are available. However, product support for these capabilities continues in the same way that it does for products beyond our Minimum Supported VersionOpens in a new tab.
Deprecated designates a feature or technology that InterSystems no longer actively develops and for which better options exist. Deprecated items should not be used for new development. The deprecated designation indicates that customers should plan to eliminate use of the feature or technology. InterSystems maintains the staff expertise to support deprecated product capabilities.
Discontinued designates a feature or technology that is no longer viable for use, even in existing applications. InterSystems feels that continued use of such technology is a risk for our customers. The reasons for this include but are not limited to:
Usage has declined to a small number of customers.
The feature has become incompatible with current technologies or security practice.
Incompatibilities between the feature or technology and our current product implementation make application maintenance prohibitive.
The feature or technology depends on discontinued content from a third party.
InterSystems Cloud Manager
As of version 2023.3, InterSystems Cloud Manager (ICM) has been deprecated. InterSystems will continue to support existing customers using this technology, but it is no longer recommended for new deployments.
Customers in the cloud who are interested in deploying and managing an InterSystems IRIS deployment with many systems are encouraged to consider using a Kubernetes platform and the InterSystems Kubernetes OperatorOpens in a new tab, which greatly simplifies the deployment of an InterSystems IRIS sharded cluster, distributed cache cluster, or standalone instance on Kubernetes.
InterSystems IRIS Natural Language Processing
As of version 2023.3, InterSystems IRIS NLP, also known as iKnow, has been deprecated. All existing functionality continues to be available as part of InterSystems IRIS and InterSystems will continue to support existing customer deployments. However, InterSystems is no longer actively developing the capability and does not recommend starting new development projects with the technology. The open-source versionOpens in a new tab of the core engine, packages as a Python module, can be used independently of InterSystems IRIS and will continue to be available. Customers looking for guidance on their current use of the technology are invited to reach out to their account teams.
InterSystems IRIS SQL Search, also known as iFind, is only partly affected. Only the Semantic and Analytic index types make use of the iKnow engine and therefore are deprecated. All other functionality and index types are not affected by this and continue to be the recommended choice for applications requiring a flexible and high-performance full text search capability.
Private Web Server (PWS)
As of version 2023.2, local installations of InterSystems IRIS will no longer install the private web server and InterSystems IRIS containers will no longer provide the private web server.
InterSystems strongly recommends that you install an external web server and configure it according to your needs, instead of using the private web server. Note that this is not a change in existing InterSystems recommendations and there is no change in the list of supported web servers.
Effective with the first EM release in 2026, the private web server will be discontinued; at that point, upgrades of existing InterSystems IRIS instances will remove the private web server.
For more details on this change, see the Private Web Server (PWS) topic in the 2023.2 new features listing.
Unstructured Information Management Architecture (UIMA) Integration
As of version 2023.1, the capability to implement the Unstructured Information Management Architecture (UIMA) has been deprecated. UIMA integration capability is still included in this release, but it will be removed in a future release.
As of version 2023.1, JAR files required to implement UIMA have been removed from releasesOpens in a new tab. To obtain these files, see Build Updated Apache UIMA JAR files.
As of version 2022.1, the Spark connector has been deprecated. As of version 2022.3, it has been discontinued. As of version 2023.1, it has been removed from releases.
Spark now has a built-in JDBC connector. If you use the Spark connector, you should modify your code to use the Spark JDBC connector.
As of version 2018.1, Zen has been deprecated. It is still included with this release, but it will be removed from a future release.
As of version 2018.1, Zen Reports has been deprecated. It is still included with this release, but it will be removed from a future release.
