Airflow vs NSQ: What are the differences?
Developers describe Airflow as "A platform to programmaticaly author, schedule and monitor data pipelines, by Airbnb". Use Airflow to author workflows as directed acyclic graphs (DAGs) of tasks. The Airflow scheduler executes your tasks on an array of workers while following the specified dependencies. Rich command lines utilities makes performing complex surgeries on DAGs a snap. The rich user interface makes it easy to visualize pipelines running in production, monitor progress and troubleshoot issues when needed. On the other hand, NSQ is detailed as "A realtime distributed messaging platform". NSQ is a realtime distributed messaging platform designed to operate at scale, handling billions of messages per day. It promotes distributed and decentralized topologies without single points of failure, enabling fault tolerance and high availability coupled with a reliable message delivery guarantee. See features & guarantees.
Airflow and NSQ are primarily classified as "Workflow Manager" and "Message Queue" tools respectively.
Some of the features offered by Airflow are:
- Dynamic: Airflow pipelines are configuration as code (Python), allowing for dynamic pipeline generation. This allows for writting code that instantiate pipelines dynamically.
- Extensible: Easily define your own operators, executors and extend the library so that it fits the level of abstraction that suits your environment.
- Elegant: Airflow pipelines are lean and explicit. Parameterizing your scripts is built in the core of Airflow using powerful Jinja templating engine.
On the other hand, NSQ provides the following key features:
- support distributed topologies with no SPOF
- horizontally scalable (no brokers, seamlessly add more nodes to the cluster)
- low-latency push based message delivery (performance)
Airflow and NSQ are both open source tools. It seems that NSQ with 15.6K GitHub stars and 2.03K forks on GitHub has more adoption than Airflow with 12.9K GitHub stars and 4.71K GitHub forks.
Airbnb, Slack, and 9GAG are some of the popular companies that use Airflow, whereas NSQ is used by Stripe, Docker, and Segment. Airflow has a broader approval, being mentioned in 72 company stacks & 33 developers stacks; compared to NSQ, which is listed in 21 company stacks and 8 developer stacks.
