* This MDB is provided to populate the SourceInfoCache with Source Information derived from the
* received trace fragments. Each clustered APM server node will receive the trace data, so each cache
* is expected to only be a local cache.
*
* Discussion regarding potential future use of a distributed cache, which would make this MDB redundant
* is associated with HWKAPM-479.
