142: Orion for Distributed Tracing in Production

ThinkingElixir.com — Tue, 14 Mar 2023 04:15:00 -0600

Orion is an interesting library created by Thomas Depierre that makes it easy to run dynamic distributed tracing in your app on production! It includes a LiveView UI for visualizing the performance and running multiple traces simultaneously. We talk with Thomas to learn more about the history, the inspirations, how it works, why it's safe to run in production, how to get performance insights, and more!

124: Caching Things Anywhere with Nebulex

ThinkingElixir.com — Tue, 08 Nov 2022 04:15:00 -0700

We wanted to go deeper on the caching library Nebulex, so we visited with the creator, Carlos Bolaños, to learn what prompted its creation. Nebulex takes a couple unique approaches to things. It supports a decorator pattern to indicate that a function should be cached without having to write the boilerplate code for reading and writing to the cache. Nebulex was inspired by Ecto, in that it supports multiple adapters to different backends like Redis, Cachex and even Horde! It also supports multiple caching strategies. It's an interesting project that aims to solve common caching challenges in new ways and we enjoyed learning more about it.

103: Vaxine.io and CRDT DBs with James Arthur

ThinkingElixir.com — Tue, 14 Jun 2022 04:15:00 -0600

James Arthur shares his project Vaxine.io, an Elixir layer built on top of a CRDT based distributed Erlang database called Antidote DB. We cover what CRDTs are and introduce how they work. We learn more about Antidote DB, the CURE protocol and especially the Vaxine.io project that adds Ecto types and makes it more approachable to Elixir applications. As applications become more global, the need for strongly consistent distributed writes becomes much more important.

101: Replicating SQLite using Litestream with Ben Johnson

ThinkingElixir.com — Tue, 31 May 2022 04:15:00 -0600

Ben Johnson explains his project Litestream.io, an OpenSource tool that replicates SQLite databases to remote servers and to backup locations like S3 for durability. We talk about how moving data out to the user creates true edge applications. We discuss what types of problems this helps solve, the architectures that become possible, and how a globally distributed Phoenix application could use this. He shares how Fly.io acquired the project and brought him on full-time to continue his work on it. Fascinating discussion that challenges many of the assumptions about how we've been building “web” systems for years.
