Amazon Unveils 'Babelfish', a SQL Server to PostgreSQL Translation Layer — When you’ve spent years building data systems on top of SQL Server or Oracle, migrating to Postgres might seem like a pipedream. AWS has unveiled Babelfish to help (eventually) – it’s designed to let Postgres work with apps built solely for SQL Server. It’s going to be open sourced in 2021 but is in...

How to Become a Redis Maintainer One Contribution at a Time — Madelyn Olson may not be the most well-known of open source developers, but chances are you’ve benefited from her work. Here’s how she went from student to contributor to a popular open source database.

A Redis Core Team Update — Last week we shared the news that Redis’s creator and long-time maintainer, Salvatore Sanfilippo was stepping back, and now we get to learn a little more about who’s taking over.

TiDB 4.0 Released: A Hybrid, Open Source HTAP Database — TiDB is an elastic, real-time Hybrid Transactional/Analytical Processing (HTAP) database built in Go(lang) that can act like a traditional relational database, a NoSQL database, or an analytical database all out of one box.

TiDB 4.0: A Peek into the Future of Databases? — Everyone who’s building a database system thinks their approach is the future and PingCAP are no different proclaiming their TiDB 4.0 release candidate as “the prototype of what the future database looks like.” The core idea is that databases will continue to get more ‘intelligent’ in scaling, scheduling and adapting to unpredictable workloads.

Choosing the Right Databases for Shopee's Applications — It’s worth noting this article is hosted by PingCAP, creators of TiDB, but beyond that it’s a look at the process of choosing which databases best suit your use cases by two engineers at a large Asian e-commerce platform (Shopee). Unsurprisingly, TiDB features heavily here, but also Redis and MySQL.

Why a Game Company Chose a Distributed SQL Database Alongside MySQL — Yes, this is a TiDB case study, but it’s interesting to see why a company chose it over other MySQL-based and NewSQL storage solutions.

Amazon Launches a Managed Apache Cassandra Service (MCS) — Cassandra is a powerful system for working with large amounts of structured data but can be tricky to maintain and manage ops-wise at scale. Enter AWS. It’s serverless-style pay-as-you-go pricing too which is neat. It’s only in 5 regions for now, but can be trialed at a low scale under the ‘free tier’ for three months.

Introducing Real-Time Anomaly Detection in Open Distro for Elasticsearch — Amazon’s Elasticsearch and machine learning teams have open sourced and released anomaly detection plugins for their controversial Elasticsearch distribution.

TiDB in the Browser: Running a Go-Based Database on WebAssembly — An interesting demo. If a database like TiDB written in Go can run in the browser, what about other complex Go apps or other database systems? SQLite is another database that is easily compiled to WebAssembly.

Lesson Learned from Queries over 1.3 Trillion Rows of Data Within Milliseconds — No big releases, so we’re leading with a detailed, technical case study this week 😄 Zhihu is China’s largest question and answer site (think Quora) with over 220 million users. This post digs into how they use TiDB to keep things running at a low latency at scale.

Amazon Announces PartiQL: A Universal, SQL-Compatible Query Language — PartiQL is a new query language that extends SQL to be able to support non-relational, schemaless and other data formats too. It’s open source and already in use internally in various AWS systems. One of its co-creators also created SQL++ (which saw implementation via Couchbase’s N1QL) several years ago.

How to Build and Run the Open Distro For Elasticsearch SQL Plugin with Elasticsearch OSS — We recently mentioned Amazon’s controversial new distribution of Elasticsearch and now we get to see one part of it in action: a plugin that lets you query an Elasticsearch store using SQL.

AWS Unveils a New, 'Open' Distribution of Elasticsearch — Elasticsearch is a popular document-oriented search and analytics engine/database and AWS is offering a new, purely open source distribution of it after concerns regarding recent additions of more proprietary features to the main project. (Look at the homepage's URL.. makes you wonder what they're planning next!)

ValuStor: A memcached Alternative Built on Scylla — Scylla itself is a highly scalable, distributed low-latency database (based on Apache Cassandra’s design) and ValuStor is an open source memcached alternative built on top of it that brings several interesting features to the party.
