    Release 2.8.1 (February 2021)


    Metrics REST API

    Release 2.8.1 sees the transition to general availability of Couchbase Sync Gateway’s Metrics REST API, which was introduced as a developer preview in release 2.8.0.

    This feature exposes Sync Gateway’s extensive stats in both JSON and Prometheus-compatible format. For more on how to enable the integration of Sync Gateway’s metrics with one of the most popular monitoring and alerting solutions — see: Prometheus Integration and Metrics REST API.

    Other Enhancements

    Custom Response Headers

    It is now possible to remove product versions from Sync Gateway responses using the hide_product_versions setting in the Config file. This customization of responses avoids revealing the version of the Sync Gateway to HTTP requests to the root path — see: Hide Product Version in Headers and CBG-1235

    Connection String Overrides

    It is now possible to use the server connection string to override the current heuristic-driven behavior for selecting internal/external networking matches — see: Couchbase Server Connection String and CBG-1276

    This release also contains a number of bug fixes for Sync Gateway — see: Release Notes 2.8.1 for contents.

    Release 2.8.0 (October 2020)

    In addition to significant performance and resilience enhancements Sync Gateway 2.8 introduces enhanced support for inter-Sync Gateway replication and a developer preview of metrics API that allows integration with Prometheus/Grafana.

    Inter-Sync Gateway Replication

    Couchbase Sync Gateway’s Inter-Sync Gateway Replicationglossary icon feature supports cloud-to-edgeglossary icon synchronization use cases, where data changes must be synchronized between a centralized cloud cluster and a large number of edge clusters whilst still enforcing fine grained access control. This is an increasingly important enterprise-level requirement.

    Prometheus Monitoring Support (Developer Preview)

    This release gives developers the chance to try-out Couchbase Sync Gateway’s new metrics API, which exposes stats in a Prometheus compatible format. This enables the integration of Sync Gateway’s metrics with one of the most popular monitoring and alerting solutions, without resorting to external data transformation.
