IN/Clojure 2020 is the 4th edition of India’s annual Clojure and ClojureScript conference. Follow twitter.com/in_clojure for updates.

Backstory

We began in Pune in 2016 and after two editions in namma Bengaluru, we’re delighted to come full circle back to apla Pune (and all those delicious bakarwadis and modaks).

As India’s premiere Clojure and ClojureScript conference, we strive to facilitate the free exchange of ideas between new and experienced programmers alike.

Over the years, IN/Clojure has served as a platform to kickstart a series of Clojure workshops and meet-ups across the country. And it has helped attendees make a strong case for Clojure, and Clojurescript adoption in their companies.

We believe that this edition of the conference, like previous editions will foster the growing Clojure community in Asia.

Who should attend?

Whether you are knee-deep writing macros that write macros, or struggling to escape the beginner’s plateau, or wondering if/why/how to adopt Clojure in your organization, or are in it purely for the joy of learning, IN/Clojure is the event bringing together a great mix of Clojure/Script masters, practitioners, and newcomers from across India and beyond.

Why Attend?

We welcome you to join nearly 149 other people and…

  • Speak: CFP is open till 20 Jan 2020.
  • Learn: We run two all-day hands-on Clojure workshops. Check ‘em out here.
  • Converse: Derive some sweet cerebral expansion from the talks, the tweetstorms, and the “hallway tracks”.
  • Inspire: Trade notes, ideas, tools, and techniques with new and experienced Clojure programmers alike (photostream).
  • Be Inspired : Start that project, that meetup, that hack night, that business, that beautiful work of art.
  • Sponsor: Help foster the growing Clojure and FP community in India/Asia.
  • Network: Meet seasoned practitioners and awesome sponsors (listed below). Hire or get hired. Acquire or get acquired ;-)
  • Grab: Some cool swag, and some fun swag, and some zany swag.
  • Party: Eat, drink, and make merry with some of the nicest people around.

Plus, this year we enjoy the company of the perennially effervescent Bozhidar Batsov; prolific Clojurist, Emacs fanatic, maintainer of CIDER, and Lisp hacker extraordinaire.

(Oh, and tickets are going, going, going… grab yours while stocks last.)

Postgres-backed Job Scheduler for Clojure

Submitted Dec 27, 2019

This talk explores a job scheduler for Clojure (now extracted into a library), which, in addition to being capable of persisting state, is resilient to the variability of a distributed system.

In this talk, we will look at the APIs that make up a core part of this library. As we discuss the internals, we’ll reflect on the ease of interop with Java’s Executor APIs. We’ll then discuss the architecture of the scheduler, the rationale for persistence, the database schema, the modeling of jobs and tasks, and the fringe benefits of persisting contextual information for each job.

To lace it all together, we will define the inputs and dissect what it translates to: initiating the schedulers, creation of jobs, discovering pending jobs on the database, and executing jobs. Towards the end, we will explore the library’s extensibility and the scope of its utilization.

Outline

  1. Context:
    - What is a general-purpose job scheduler?
    - What currently exists, and how does this library compare?
  2. Architecture:
    - Walkthrough
    - Motivations
    - Internal APIs
  3. Library APIs:
    - Defining jobs
    - Defining tasks, rules, and metadata for jobs
    - Scheduling jobs
  4. Rationales:
    - Database schema
    - Why is it required for job schedulers to be persistent, and what purpose does persisting jobs’ and tasks’ state serve?
    - What purpose does metadata serve?
  5. Lacing it all together.
  6. Roadmap of the library.

Requirements

Minimal experience of working with Clojure and Postgres is a nice-to-have prerequisite, but not a compelling requirement.

Speaker bio

I’m a software engineer at nilenso, where I primarily work on building a platform for incentivising Gojek drivers. Prior to nilenso, I spent a large chunk of my programming career working with Kotlin and Java (among other things) to solve various problems across healthcare technology.
