What is Nebulex?

Overview of Nebulex, an Elixir open source cashing library
17 August 2017   505

Caching is one of the mos popular methods to improve performance. There are different cashing options in Elixir available. But most of them are focused on local caching. Most of the cases developers deal with distributed systems, which involves at least two nodes, therefore, sometimes a local cache might be not enough. So, there should be a a tool or library that give the ability to create different caching topologies depending on our needs; it could be a simple local cache, a distributed or partitioned cache, or even a near cache topology. Nebulex can help you with it.

Nebulex is an open source caching library written in Elixir, with Ecto influence. Nebulex features:

  • Simple and fluent API inspired by Ecto
  • Flexible and pluggable architecture like Ecto – based on adapter pattern
  • Built-in cache adapters
    • Local generational Cache
    • Distributed or Partitioned Cache
    • Multi-level Cache
  • Support for different cache topologies – Partitioned, Near, etc.
  • Time-based expiration
  • Pre/post execution hooks
  • Transactions (key-locking)
  • Key versioning – optimistic offline locks
  • Optional statistics gathering

Additionally, Nebulex has good documentation, starting guide, and available examples. Developers ask to create an issue if any bugs appear.

Club ElixirLangMoscow invites all lovers of Elixir, Erlang and functional programming languages to the next meeting of our club. This time the event was decided to be held in the "Dear, I will call back" bar. Because, what could be better than listening to interesting reports for a glass of beer.

The report will highlight the Agala framework - a platform for real-time interaction with third-party services. Currently, this platform has implemented bots for Telegram and Vk, which are used in the combat environment in our company. Let's analyze the main differences from the known solutions for creating bots on Elixir, consider the internal structure of the platform and learn how to support any necessary third-party service.

This will be an introductory report with Apache CouchDB and its ecosystem. Main features and capabilities. Details of the implementation of the replication protocol and why this is important. Forks: Couchbase, Cloudant - what are the differences and why should not they be confused with the original project. The history of clustering, what happened in the end in 2.0 and how it works. What is interesting about the new release and where the project is heading.

As a pleasant chip, the bar will prepare an "Elixir" cocktail especially for us. Admission is free, everyone pays their bill.
