Mounting object storage in Netflix’s media processing platform By Barak Alon (on behalf of Netflix’s Media Cloud Engineering team) MezzFS (short for “Mezzanine File System”) is a tool we’ve developed at Netflix that mounts cloud objects as local files via FUSE. Our object storage service splits objects into many parts and stores them in S3.

Replay Traffic Testing Replay traffic refers to production traffic that is cloned and forked over to a different path in the service call graph, allowing us to exercise new/updated systems in a manner that simulates actual production conditions. It helps expose memory leaks, deadlocks, caching issues, and other system issues.

Where aws ends and the internet begins is an exercise left to the reader. KeyValue is an abstraction over the storage engine itself, which allows us to choose the best storage engine that meets our SLO needs. For these requests where caching removed KeyValue from the hot path, we were able to greatly speed things up.

In addition, DynamoDB Accelerator (DAX) a fully managed, highly available, in-memory cache further speeds up DynamoDB response times from milliseconds to microseconds and can continue to do so at millions of requests per second. Auto Scaling is on by default for all new tables and indexes.

Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. As database performance is heavily influenced by the performance of storage, network, memory, and processors, we must understand the upper limit of these key components.

The beauty of persistent memory is that we can use memory layouts for persistent data (with some considerations for volatile caches etc. This is left as an exercise for the application developer at present. in front of that memory , as we saw last week). In particular, it’s goodbye to the POSIX interface. What about security?

sounds like a homework exercise of purely academic value. Networks, PCIe busses, CPU interconnects, memory busses, and storage devices (both throughput and IOPS), all have fixed limits. In some cases, a benchmark may appear to exceed network bandwidth because it returns from a local memory cache instead of the remote target.
