The Changelog The Changelog #429

Community perspectives on Elastic vs AWS

This week on The Changelog we’re talking about the recent falling out between Elastic and AWS around the relicensing of Elasticsearch and Kibana. Like many in the community, we have been watching this very closely.

Here’s the tldr for context. On January 21st, Elastic posted a blog post sharing their concerns with Amazon/AWS misleading and confusing the community, saying “They have been doing things that we think are just NOT OK since 2015 and it has only gotten worse.” This lead them to relicense Elasticsearch and Kibana with a dual license, a proprietary license and the Sever Side Public License (SSPL). AWS responded two days later stating that they are “stepping up for a truly open source Elasticsearch,” and shared their plans to create and maintain forks of Elasticsearch and Kibana based on the latest ALv2-licensed codebases.

There’s a ton of detail and nuance beneath the surface, so we invited a handful of folks on the show to share their perspective. On today’s show you’ll hear from: Adam Jacob (co-founder and board member of Chef), Heather Meeker (open-source lawyer and the author of the SSPL license), Manish Jain (founder and CTO at Dgraph Labs), Paul Dix (co-founder and CTO at InfluxDB), VM (Vicky) Brasseur (open source & free software business strategist), and Markus Stenqvist (everyday web dev from Sweden).

Why the Dgraph team chose Badger over RocksDB

This blog post is about Badger, the key-value database that makes it all happen under the hood, housing all Dgraph data, including Raft logs.

There are many key-value store options in Go-land. Still, the Dgraph team decided to roll their own solution 18 months back. Was it a bad case of NIH? A good idea? Would they do it all over again? This article answers those questions in-depth.

There and back again (Dgraph's tale)

This week we talk with Manish Jain about Dgraph, graph databases, and licensing and re-licensing woes. Manish is the creator and founder Dgraph and we talked through all the details. We covered what a graph database is, the uses of a graph database, and how and when to choose a graph database over a relational database. We also talked through the hard subject of licensing/re-licensing. In this case, Dgraph has had to change their license a few times to maintain their focus on adoption while respecting the core ideas around what open source really means to developers.
