PgDog is funded and coming to a database near you

PgDog 获得融资，即将登陆您的数据库

Postgres is the only database you need. The reason DBs like Mongo or Dynamo exist is because Postgres has a scaling problem. If you could make it just work, with 100 TB+ tables and 1M queries per second, we don’t think you would use anything else. This is why we are building PgDog. Same old Postgres, just with a proxy in front of it, to make it horizontally scalable.

Postgres 是你唯一需要的数据库。像 Mongo 或 Dynamo 这样的数据库之所以存在，是因为 Postgres 存在扩展性问题。如果能让它在处理 100TB 以上的数据表和每秒 100 万次查询时依然顺畅运行，我们相信你不会再考虑其他选择。这就是我们开发 PgDog 的原因。它依然是你熟悉的 Postgres，只是在前端增加了一个代理，使其具备了水平扩展能力。

You can deploy PgDog anywhere, including on-prem and in your cloud account: pull our Docker image, change your DATABASE_URL, and make us do the work. Our status PgDog is serving more than 2M queries per second, in production, across dozens of deployments. We sharded over 20 TB that we know about. PgDog is open source and anyone can just deploy it, and they do: we have over 1.4M Docker pulls on GitHub. A new version comes out every week, on Thursdays. Our Discord community is growing. We are there, every day, to answer questions and provide support.

你可以在任何地方部署 PgDog，包括本地环境和你的云账户：只需拉取我们的 Docker 镜像，修改 DATABASE_URL，剩下的工作交给我们。目前，PgDog 在数十个生产环境中每秒处理超过 200 万次查询。据我们所知，我们已经分片处理了超过 20TB 的数据。PgDog 是开源的，任何人都可以部署，事实也确实如此：我们在 GitHub 上的 Docker 拉取量已超过 140 万次。我们每周四发布一个新版本。我们的 Discord 社区正在不断壮大，我们每天都会在那里回答问题并提供支持。

Why us PgDog is a small, three-person startup. So, why use our stuff and trust us with your data? We are infrastructure engineers, application engineers and generalists. We built apps on Postgres before it was cool and made it work at massive scale. I ran Postgres at Instacart, where we scaled the company 5x in April of 2020. The biggest problem we had was making Postgres serve 100,000s of grocery delivery orders per minute. We sharded Postgres on RDS, Aurora and EC2. We fixed the actual problem, using first principles (and a lot of code). The same technology is now available as an open source product.

为什么选择我们？PgDog 是一家只有三人的小型初创公司。那么，为什么要使用我们的产品并将数据托付给我们呢？我们是基础设施工程师、应用工程师和通才。在 Postgres 流行之前，我们就已经在其上构建应用，并使其在大规模场景下稳定运行。我曾在 Instacart 负责 Postgres 的运维，2020 年 4 月，我们将公司业务规模扩大了 5 倍。当时我们面临的最大挑战是让 Postgres 每分钟处理数十万份杂货配送订单。我们在 RDS、Aurora 和 EC2 上对 Postgres 进行了分片。我们运用第一性原理（以及大量的代码）解决了实际问题。现在，这项技术已作为开源产品提供给大家。

Building PgDog is not a pivot. For us, scaling Postgres has been, and is, the only goal. We built PgDog to run in your cloud, in your colo rack, on-prem, or on your laptop. Wherever you need it, PgDog works, with no dependencies or hidden serverless costs. If you can provide CPUs, our multithreaded code will use them all. Postgres adoption is only going to increase. With $5.5M from Basis Set, YC, Pioneer Fund and other great investors, we have years of runway, and we are going to make Postgres just work, for everyone, at any scale. – Lev

开发 PgDog 并非转型。对我们而言，扩展 Postgres 过去是、现在依然是我们的唯一目标。我们构建 PgDog 是为了让它能在你的云端、托管机架、本地环境或笔记本电脑上运行。无论你在哪里需要它，PgDog 都能正常工作，且没有依赖项或隐藏的无服务器成本。只要你能提供 CPU，我们的多线程代码就能充分利用它们。Postgres 的采用率只会越来越高。在获得 Basis Set、YC、Pioneer Fund 等优秀投资者的 550 万美元融资后，我们拥有了充足的资金储备，我们将致力于让 Postgres 在任何规模下都能为每个人顺畅运行。—— Lev

P.S. We are building an Enterprise edition of PgDog to make it easier to run in AWS. It comes with SLA-backed support from our team. Give us a call if you want to try it out.

附：我们正在开发 PgDog 企业版，以便更轻松地在 AWS 上运行。它附带我们团队提供的 SLA 支持。如果你想尝试，请联系我们。
