Redis Explained
Redis Explained InfographicWhat is Redis?Redis (“REmote DIctionary Service”) is an open-source key-value database server. The most accurate description of Redis is that it's a data structure server. This specific nature of Redis has led to much of its popularity and adoption amongst developers. 👋🏾You are reading Architecture Notes! Crave some byte-sized bites of this? Join me on Twitter. If it's
GPT-4, GPT-3.5 の API を利用して JSON だけ生成する (Function calling)
先日 OpenAI API のアップデートが以下のように発表されました。 一番の注目は Function calling じゃないでしょうか？ 名前から「関数を呼び出せるのかな？」と一番最初に想像しちゃいますが、この機能の革新的な部分は「JSON を作成してくれる」ところだと思っています。 JSON を作れると嬉しいことがいっぱいありますね！ ダミーデータの作成 生成した JSON をそのままレスポンスとして返すエンドポイントの作成 テストとしても良い 関数や外部 API の呼び出し 今までは難しかった JSON の作成 今まで、JSON を作成してもらうにあたって gpt-3.5-turbo を用いて JSON を作成させようとするとほぼ失敗していました。それで gpt-4 のモデルを利用して JSON を作成させますが、このモデルはほとんど正確になる一方で処理速度がかなり遅くなる点がネ

Build a CQRS event store with Amazon DynamoDB | Amazon Web Services
AWS Database Blog Build a CQRS event store with Amazon DynamoDB The command query responsibility segregation (CQRS) pattern, derived from the principle of command-query separation, has been popularized by the domain-driven design community. CQRS architectures that use event sourcing save generated events in an append-only log called an event store. By using event sourcing, you can, among other ben
Distributed systems provide a particular challenge to program. They often require us to have multiple copies of data, which need to keep synchronized. Yet we cannot rely on processing nodes working reliably, and network delays can easily lead to inconsistencies. Despite this, many organizations rely on a range of core distributed software handling data storage, messaging, system management, and co

How are Unix pipes implemented?
This article is about how pipes are implemented the Unix kernel. I was a little disappointed that a recent article titled “How do Unix pipes work?” was not about the internals, and curious enough to go digging in some old sources to try to answer the question. What are we talking about? Pipes are “perhaps the single most striking invention in Unix” — a defining characteristic of the Unix philosoph

SRE for single-tiered software applications | Google Cloud Blog
In cloud operations, we often hear about the benefits of microservices over monolithic architecture. Indeed, microservices help manage hardware being abstracted away and push developers towards resilient, distributed designs. However, many enterprises still have monolithic architectures which they need to maintain. For this post, we’ll use Wikipedia’s definition of a monolith: “A single-tiered sof

An interface is not an interface - Recent thoughts about clean coding - spacelyのブログ

Is it about a set of rules, and we are guaranteed to achieve cleanness as long as we follow them? Or is it about abstract principles, which we c

Simplifying distributed ML through a unified API Writing fault-tolerant distributed programs is complex and a process that’s prone to errors. For example, consider the distributed evaluation of a deep network. The first step is to send a multi-GB model to hundreds of worker machines without overwhelming the network. Then, data readers must coordinate to ensure that all data is queued for processin
While these fixes moved the needle, they had limitations. By analyzing our database traffic, we learned that writes— like gathering, updating, or deleting data—contributed to a significant portion of database utilization. Additionally, not all reads or data fetching could be moved to replicas due to application sensitivity to replication lag. So, from both a read and write perspective, we still ne

What is CockroachDB Serverless? If you’ve created a database before, you probably had to estimate the size and number of servers to use based on the expected traffic. If you guessed too low, your database would fall over under load and cause an outage. If you guessed too high or if your traffic came in bursts, you’d waste money on servers that are just sitting idle. Could there be a better way? Se
