A Tale About Migrating a PostgreSQL Database Between Providers — A story from the folks at Percona about migrating a production Postgres database between two DBaaS platforms by using an intermediate server.

How Container Networking Affects Database Performance — Networking has an outsized impact on database performance in most Kubernetes environments and Percona set out to run some benchmarks measuring database throughput vs network bandwidth using numerous Kubernetes container networking plugins.

▶  Streaming Music to Livestreamers — Learn about Pretzel Rocks, a service built to provide stream-safe music for livestreamers.

Building a Scalable Product Recommender with Keras, Docker, GCP, and GKE — Pair is a curious app that takes a product image, analyzes its design features, then recommends other products with similar stylistic elements.

awesome-mongodb: A Curated List of Awesome MongoDB Resources, Libraries, Tools and Applications — We’ve shared this before, but it is still seeing occasional updates, and remains a decent resource for MongoDB users of all types.

Hackers Have Wiped and Defaced More Than 15,000 Elasticsearch Servers — We’ve seen many stories over the years of remotely accessible databases being targeted en masse by hackers and now it’s Elasticsearch’s turn. A reminder, if you needed one, to audit your databases and overall security situation.

Running 'Redis' on NVMe with ScyllaDB? — Redis is a popular in-memory data structure server but ScyllaDB has implemented (very) basic Redis protocol/command support enabling it to be used in a similar way. How does the initial performance compare with the real thing?

GridDB Hits 5 Million Writes Per Second and 60 Million Reads Per Second with 20 Nodes — GridDB is a scalable, in-memory NoSQL time series database from Toshiba aimed at the IoT world, and to prove just how scalable, they’ve run it across 20 nodes on Google Cloud Platform and hit some huge throughput figures.

Announcing DataPub: New Virtual Meetup for Open Data Enthusiasts 🎉 — Love open datasets, hearing about community members’ projects, and learning how to build your own? Join us on Mar 31st for DataPub (100% virtual) to learn ways to use public data to monitor situations (including COVID-19), rework inefficient queries, and more.

AWS Adds Role-Based Access Control to Amazon DocumentDB — DocumentDB is AWS’s ‘MongoDB compatible’ document database service and now you can grant users roles (e.g. read, readWrite or dbOwner).

If You're Running memcached 1.6.0 or 1.6.1 Update ASAP — A nasty buffer overflow vulnerability was shared publicly in a GitHub issue complete with a POC so you want to upgrade 1.6.0 or 1.6.1 installs to 1.6.2 as soon as possible.

A Look at Embedded SQL in C for Postgres with ecpg — A quick look at what is generously called a ‘vintage technology’ (i.e. old fashioned) where you write SQL directly inline within, say, a C program and compile it to handle all the database work behind the scenes. I’d never seen this style of programming before, so it’s interesting even if I’ll never use it.

9 Offbeat Databases Worth A Look — Popular, well tested databases have a huge benefit in sense of community, documentation, and proven performance, but keeping an eye on newer or less common databases can prove educational (or, in the best case, perfectly suited to your unusual use cases!)
