Content Server Actuator Endpoint to Suspend Blob Collector

The Content Server has a new Spring Boot actuator endpoint "blobcollector" that can be used to suspend (and resume) deletion of unused blobs at runtime.

Suspending blob deletion is a required step when making backups of non-transactional blobs stores like a file blob store. Previously, this required a change to configuration property sql.store.collector.suspend and a server restart. With the new actuator endpoint, no restart is required anymore. See section "Basics of Operation | Actuator Endpoints | Content Server Blob Collector Endpoint" in the Operations Basics Manual for details.
