This session explores the architectural shifts required to allow clients to bypass the Primary entirely and fetch data directly from the OSDs. We will discuss the mechanics of offloading data retrieval, decoding, and validation to the client side. Finally, we will share an in-depth performance analysis, highlighting the reduction in overall network latency and improvements in tail latencies across various workload profiles.
