Swarm 12.1 - Updated May 2021

• Settings updates: Some setting updates in Content Gateway 7.5.

• Improvement: Improved error handling in Content Gateway 7.5.

Swarm 12.1 - Updated May 2021

• Defragmentation Optimizations: This includes additional parallelism across disk volumes for nodes with many drives and new tuning features for small-object/high-turnover use cases.

• Enhancements to Overlay Index Initialization: These improve the startup performance at reboot by allowing a node's index to quickly reach an authoritative state and reduce the disruption of rolling cluster reboots.

• Operational Improvements: This release contains several optimizations for administrative operations, better statistical reporting, and expanded diagnostic information.

• Third-party Software Updates: Third-party software packages within Swarm are updated to track with CVE recommendations.

Swarm 12.0 - Updated March 2021

• System Domain: In the Content UI, Swarm's modern features such as metadata searching, policy/access control, and metering for unnamed and untenanted objects can now be used. See System Domain and Legacy Mode for Gateway for more on this feature.

• Elasticsearch: Improvements to the initialization of the metadata search indices to verify Elasticsearch's automatic field data typing is correct.

Swarm 12.0 - Updated February 2021

• Single Sign-On Enhancements: The SAML single sign-on support in Gateway and Content UI is enhanced to allow better mixing of identity management systems for separate tenants in Swarm. 

• Swarm Improvements: Swarm Storage improvements for 12.0 or upgrades from an earlier version.

Swarm 12.0 - Updated December 2020

• Remote Synchronous Write: In the Content UI, specific domains and buckets can now be configured to broadcast new content to all remote sites immediately. This feature, Remote Synchronous Write, delays write completion until replicas exist in every remote cluster. This setting allows supporting applications that require guarantees that backups are committed to every site, and to support publishing requirements to be able to read new content from any remote site immediately after ingest.

• Folder Listing UI: With Gateway 7, folder listing support across Swarm clients (Content UI, SwarmFS, and S3) is rearchitected and centralized. Folder listing is what renders the virtual folders (prefixes) on named Swarm objects (such as FY2019/Q3/object.jpg) into familiar folders on the users' file systems. The service leverages newer Elasticsearch features and is not bound by ES listing limits.

  The Content UI now presents these folders as walkable directories, with these key benefits:
  
  

  • Prefix Filtering: By parsing object prefixes into hierarchical folders in real time, the Content UI provides users a fast and intuitive way to view and manage content in a bucket, automatically.

  • Empty Folders: The Content UI allows creation and persistence of new, empty folders that are ready to receive files. This allows planning and setting up organizing structures ahead of time, to guide content uploaders to use the organization. A content architecture can be enforced to avoid the risk users perform bulk uploads using a malformed prefix by having them upload directly to folders.

  • Recursive Deletes: The Content UI allows deleting virtual folders, which recursively deletes all objects and subfolders they contain. 

• Single Sign-On Across UIs: SAML 2.0 support in Content Gateway facilitates implementing single sign-on for users. Adding SSO allows granting access to the Storage and Content UIs using centrally managed identity credentials, such as the organization's Gmail accounts.

• S3 Backup to AWS Glacier: S3 Backup feeds can now be implemented to back up to and restore from archival ("cold") storage. The cost-effectiveness of the disaster recovery solution can be maximized by backing up Swarm to an S3 bucket with a storage class such as Glacier.

• Elasticsearch 7: Staying current with the latest version of Elasticsearch supported by Swarm reduces the complexity of cluster upgrades, tooling, and troubleshooting. The last several Elasticsearch releases brought improvements in performance, resilience, and cost-efficiency, and upgrading to Elasticsearch 7 from 6 does not require cluster reindexing.

• SwarmNFS is now SwarmFS: SwarmNFS is renamed SwarmFS to reflect the greater scope of capabilities. The latest version of SwarmFS has improvements for performance and maintainability in NFS integrations with Swarm.

• Grafana Dashboards: New versions of public Caringo dashboards are published on grafana.com. The dashboards have links to each other on the top navigation bar:

  • Caringo Swarm System Monitoring v12.0 (cluster view)

  • New: Caringo Swarm Node View (detailed view)

  • Caringo Swarm Gateway Monitoring v7 

  • Caringo Videoclipping Dashboard v1.0.1 

  • Caringo Swarm AlertManager v12
