If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls. We use Mantis for processing the stream of collected traces, and we use Cassandra for storing traces.

Annotations Sometimes people describe annotations as tags but that is a limited definition. Given the requirements and the expertise in our team we decided to choose Cassandra as the source of truth for storing annotations. We started with a 12 nodes cassandra cluster, and scaled up to 24 nodes to support current data size.

Two fixes have been delivered in this ticket: – Sessions can now be replayed from specific user actions on the Session details page – For user tags that contain a slash (/) character, users can navigate from the Session details page to the User details page by using breadcrumbs. Fix for Cassandra tables size calculation.

Each incoming request on the core service node is tagged and classified into various groups. We had used other databases like Berkeley DB, Lucene, Cassandra in past but we migrated over time all of them to MySQL because of its engineer/ops familiarity and scalability. Document store. Video Transcoding. Permissions. Recommendations.
