What it is

Petrel provides a suite of Python-based tools to write, submit, debug, and monitor Apache Storm topologies. It simplifies the process of working with Storm in pure Python environments.

Petrel stands out as the only pure Python toolset for managing and monitoring Apache Storm topologies, offering developers a streamlined workflow within familiar environments.

When it fits — and when it doesn’t

A good fit for

  • Python developers working with Apache Storm for real-time data processing

  • Data engineers who need to debug and monitor complex Storm topologies in a Python environment

Look elsewhere if

  • Developers looking for a full-stack solution that includes UI/UX design tools

  • Teams requiring cloud-based managed services for their real-time data processing needs

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited integrations with other data processing frameworks

    Primary integration is with Apache Storm; lacks native support for Spark or Flink

  2. 02

    Frequent breaking changes between versions

    v0.1 to v0.2 migration required rewriting chain definitions, impacting stability and maintenance effort

  3. 03

    Small community and limited third-party support

    Few active contributors on GitHub; sparse documentation and example projects

What it does well

  • Pure Python environment for Storm topology management

  • Simplified debugging and monitoring of Storm topologies

  • Integration with Apache Storm ecosystem
