These principles reduce resource usage by being more efficient and effective while lowering the end-to-end latency in data processing. It is responsible for listening to incoming events and requests and prioritizing different tables and actions to make the best usage of the available resources. More processing resources.

Plans & Offers Definitions Let’s define what a plan and an offer is at Netflix. This means we need to distinguish between availability of SKUs and eligibility for SKUs. You can think of eligibility as something that is applied at the user level, while availability is at the country level.

This boils down to a single digit µs latency toleration in the tail for far memory, and in addition to security and privacy concerns, rules out remote memory solutions. Zswap is readily available and runs as a swap device in the Linux kernel. ML-based auto-tuning. Enter zswap! Google use zswap to implement their far memory tier.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

The data shape will dictate capacity planning, tuning of the backbone, and scalability analysis for individual components. They have a clear input and output definition, and often a schema as well. Are there inherent time relationships in the messages that need to be preserved as they travel across the system? At least once?

Finally, not inlining resources has an added latency cost because the file needs to be requested. As such, a micro-optimization is, again, how you probably need to fine-tune things on a low level to really benefit from it. Luckily, other lower-level tools are available to help with this. What Does It All Mean?

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. Stay tuned! (vf, QUIC has a higher encryption overhead. Conclusion.

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. Many of these systems support I/O ordering with a stable media cache and subsequently combine and/or split I/O requests across available subsystem resources to complete the storing to physical media.
