3.2.0 — September 2024
|
Do not deploy Eventing/Sync Gateway until all SGW nodes are at version 3.2. For older Sync Gateway versions that do not write import XATTRs, Eventing functions may encounter infinite recursions and duplicate mutations if deployed in a mixed mode SGW environment. This can only happen during a mixed mode of SGW with a 3.2 version and an older version during an upgrade and a new Eventing/Sync Gateway function is deployed. |
Audit Logging for Sync Gateway
Couchbase now provides Audit Logging support for Sync Gateway. Audit Logging provides tools for administrators to track operational irregularities and to support regulatory and security compliance standards.
