StormCrawler

StormCrawler is a collection of resources for building low-latency, customisable and scalable web crawlers on Apache Storm.

StormCrawler has been incubating since 2024-03-19.

Three most important unfinished issues to address before graduating:

There are no remaining issues. After list discussions with our mentors, we have confirmed that it would be the right time for graduation.0

Are there any issues that the IPMC or ASF Board need to be aware of?

None.

How has the community developed since the last report?

StormCrawler remains well-established, with a steady user base over the past decade. While the number of committers and contributors remains small, the project's activity level is comparable to some established TLPs.

Seasoned committers with experience across various ASF projects continue to contribute, ensuring the project's stability and sustainability.

Although community growth has been minimal (but did happen), there has been some progress.

Additionally, the rise of generative AI has shifted focus toward production-ready, turnkey solutions, reducing the incentive for many users to contribute directly to StormCrawler. Instead, they often prefer to adopt mature, off-the-shelf software like StormCrawler rather than actively participating in development.

This industry trend may explain the limited influx of new contributors despite the project's ongoing relevance.

How has the project developed since the last report?

The project has seen steady progress with various bug fixes and dependency updates. Additionally, there have been some external contributions to the documentation, indicating ongoing interest and engagement from the community.

Other:

The project is well-established, has maintained steady activity, and has experienced contributors who are familiar with ASF processes. While community growth has been modest, the project's engagement level and stability suggest it is ready for graduation.

The presence of seasoned committers and ongoing development efforts further support this assessment.

Date of last release:

2025-03-24

2024-09-21

Have your mentors been helpful and responsive?

Yes, our mentors have been supportive, providing guidance throughout the process. They have been available for discussions, particularly regarding the project's readiness for graduation, and have helped ensure we are on the right track.

Their experience and insights have been valuable in navigating ASF Incubator processes.

Is the PPMC managing the podling's brand / trademarks?

Yes. The name was approved by VP Trademarks.
