Rootconf 2018

On scaling infrastructure and operations

##About Rootconf 2018 and who should attend:

Rootconf is India’s best conference on DevOps, SRE and IT infrastructure. Rootconf attracts systems and operations engineers to share real-world knowledge about building reliable systems.

The 2018 edition is a single track conference. Day 1 – 10 May – features talks on security. Colin Charles (chief evangelist at Percona Foundation), Pukhraj Singh (former national cybersecurity manager at UIDAI), Shamim Reza (open source enthusiast), Alisha Gurung (network engineer at Bhutan Telecom) and Derick Thomas (former network engineer at VSNL and Airtel Bharti) will touch on important aspects of infrastructure, database, network and enterprise security.

Day 2 – 11 May – is filled with case studies and stories about legacy code, immutable infrastructure, root-cause analysis, handling dependencies and monitoring. Talks from Exotel, Kayako, Intuit, Helpshift, Digital Ocean, among others, will help you evaluate DevOps tools and architecture patterns.

If you are a:

  1. DevOps programmer
  2. Systems engineer
  3. Architect

Production Report - Using Apache Flink as a microservice for stateful asynchronous processing

Submitted Mar 3, 2018

This talk highlights why we chose flink as a microservice for stateful asynchronous event processing and challenges we faced in production, how we solved those and recommendations for productionization of the applications using Apache flink.

Key takeaways:

  • Architecture pattern of using Flink/similar platform as a microservice for statuful async event processing
  • Flink fault tolerance concepts in-depth understanding
  • Production issues/challenges faced and insights on how to solve (& also prevent) them

Basic understanding of stream processing will be an advantage.

Outline #

  • Brief summary of what is flink and important terminologies
  • Flink as a microservice for asynchronous stateful event stream processing
    • Challenges in doing it in a conventional way
  • Prerequisite concepts
    • Fault tolerance and checkpointing
    • Scalable partitioned state
    • State Backend - Rocksdb
    • Asynchronous checkpointing details
  • Production Experiences
    • Flink taskmanager failover time tuning
      • Failure detection mechanism
    • Tuning Akka Deathwatch
    • How state leaks happen and how to prevent and monitor them
    • How to clear old state (result of state leak) of running system, without taking downtime
    • How state size and checkpointing can cause processing delays and how to tune it
  • Recommendations & Summary

Speaker bio #
