By: Rajiv Shringi , Oleksii Tkachuk , Kartik Sathyanarayanan Introduction In our previous blog post, we introduced Netflix’s TimeSeries Abstraction , a distributed service designed to store and query large volumes of temporal event data with low millisecond latencies. Today, we’re excited to present the Distributed Counter Abstraction.
Its partitioned log architecture supports both queuing and publish-subscribe models, allowing it to handle large-scale event processing with minimal latency. Apache Kafka uses a custom TCP/IP protocol for high throughput and low latency. Apache Kafka, designed for distributed event streaming, maintains low latency at scale.
Traces are used for performance analysis, latency optimization, and root cause analysis. The OpenTelemetry website provides detailed documentation for each language to guide you through the necessary steps to set up your environment. Capture critical performance indicators such as request latency, error rates, and resource usage.
Rajiv Shringi Vinay Chella Kaidan Fullerton Oleksii Tkachuk Joey Lynch Introduction As Netflix continues to expand and diversify into various sectors like Video on Demand and Gaming , the ability to ingest and store vast amounts of temporal data — often reaching petabytes — with millisecond access latency has become increasingly vital.
The challenges with service management included: Stale documentation OS Updates High cognitive overhead A lack of continuous testing Scaling Image Creation Our existing AMI baking tool Aminator does not support Windows so we had to leverage other tools. Services are more reliable, testable, and documented.
Whether tracking internal, workload-centric indicators such as errors, duration, or saturation or focusing on the golden signals and other user-centric views such as availability, latency, traffic, or engagement, SLOs-as-code enables coherent and consistent monitoring throughout the environment at scale.
While there is plenty of well-documented benefits to using a connection pooler, there are some arguments to be made against using one: Introducing a middleware in the communication inevitably introduces some latency. A connection pooler is an almost indispensable part of a production-ready PostgreSQL setup.
Prodicle Distribution Prodicle Distribution allows a production office coordinator to send secure, watermarked documents, such as scripts, to crew members as attachments or links, and track delivery. One distribution job might result in several thousand watermarked documents and links being created.
By collecting and analyzing key performance metrics of the service over time, we can assess the impact of the new changes and determine if they meet the availability, latency, and performance requirements. They enable us to further fine-tune and configure the system, ensuring the new changes are integrated smoothly and seamlessly.
Amazon ElastiCache (see AWS documentation for Memcached and Redis ). The example below visualizes average latency by API name and stage for a specific AWS API Gateway. Stay tuned for updates in Q1 2020. Amazon CloudFront. Amazon Cognito. Amazon EC2 Spot Fleet. Amazon Elastic Container Service (ECS). Amazon EMR. Requirements.

Any scenario in which a student is looking for information that the corpus of documents can answer. Wrong document retrieval : Debug chunking strategy, retrieval method. For example, if youre building a document QA tool, upgrading from basic OCR to AI-powered extractionthink Mistral OCRmight give the biggest lift on your system!
The eval process combines: Human review Model-based evaluation A/B testing The results then inform two parallel streams: Fine-tuning with carefully curated data Prompt engineering improvements These both feed into model improvements, which starts the cycle again. Were experiencing high latency in responses.
This enables us to use our scale to increase throughput and reduce latencies. Here, based on the video length, the throughput and latency requirements, available scale etc., To aid our transition, we introduced another Cosmos microservice: the Document Conversion Service (DCS). VQS is called using the measureQuality endpoint.
The maintenance costs over time for an Alpakka-Kafka-based solution is much lower than that for the other solutions, as both Akka and Alpakka-Kafka are mature ecosystems in terms of documentation and community support, having been around for at least 12 and 6 years, respectively. million elements.
Improved performance : MongoDB continually fine-tunes its database engine, resulting in faster query execution and reduced latency. ” MongoDB upgrades follow a well-documented and structured approach, ensuring the process goes smoothly.
In addition to availability, our respondents focus most heavily on supporting the following data attributes: “accessibility, accuracy, authoritativeness, freshness, latency, structuredness, ontological typing, connectedness, and semantic joinability.” To address this, rigorous rollout processes are required.
Passive instances across regions are also possible, though it is recommended to operate in the same region as the database host in order to keep the change capture latencies low. Stay Tuned DBLog has additional capabilities which are not covered by this blog post, such as: Ability to capture table schemas without using locks.

Here's some output from my zfsdist tool, in bcc/BPF, which measures ZFS latency as a histogram on Linux: # zfsdist. Tracing ZFS operation latency. There's a lot about Linux containers that isn't well documented yet, especially since it's a moving target. Hit Ctrl-C to end. ^C
However in the Skylake microarchitecture (you can see a list of CPUs here ) the PAUSE instruction changed and in the documentation it says “the latency of the PAUSE instruction in prior generation microarchitectures is about 10 cycles, whereas in Skylake microarchitecture it has been extended to as many as 140 cycles.”
The main objective of this post is to share my experience over the past years tuning MongoDB and centralize the diverse sources that I crossed in this journey in a unique place. The CFQ works well for many general use cases but lacks latency guarantees. On the other hand, MongoDB schema design takes a document-oriented approach.
Tip: When evaluating quality, compression and fine-tuning of modern formats, Squoosh.app ’s ability to perform a visual side-by-side comparison is helpful. CDN servers are often located closer to users than origin servers and can have a shorter round-trip times (RTT), improving network latency. Large preview ).
Here are 8 fallacies of data pipeline The pipeline is reliable Topology is stateless Pipeline is infinitely scalable Processing latency is minimum Everything is observable There is no domino effect Pipeline is cost-effective Data is homogeneous The pipeline is reliable The inconvenient truth is that pipeline is not reliable.
A latency outlier issue that happened every 15 minutes. This is documented in the Netflix [culture deck], and after three years I still find it true. For Linux, I've also done tuning, kernel analysis, [gdb], testing of [hist triggers], testing of some perf patches, and contributed a few trivial patches of my own.
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. hundreds of pages spread over more than seven documents.

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).
Faster detection of a bad connection is accomplished when there’s a lower value, while latency or intermittent network issues may be better served by increasing it slightly – although overly long timeouts can result in application hang-ups with little chance for an established link. Careful consideration must be given before making changes.
Each of the two vector units can issue one FMA instruction per cycle, assuming that there are enough independent accumulators to tolerate the 6-cycle dependent-operation latency. of the “adjusted peak performance”, there is no longer a significant upside to performance tuning.
