As always at the start of another new month, let's have a look at what happened at Hop over the last month. Here's the recap for January 2022!

Hop Graduation - Apache Software Foundation Press Release

Everyone who follows Apache Hop knows we graduated to a Top-Level Project in the final days of 2021.

Since not everyone follows Hop (yet), the Apache Hop PMC worked with the Apache Software Foundation to issues a press release that was sent out on January 18th.

Home to over 350 projects, some of which are wildly popular, the ASF has access to a massive audience. The press release created a major surge in the Apache Hop website visitor and downloads. With the increase in numbers, we saw a lot of new attention from Asia, especially China.

We’d like to take this opportunity to welcome all new Hop users and enthusiasts the Apache Hop community!

Apache Hop 1.1.0

On January 24th, the Apache Hop PMC and community released Apache Hop 1.1.0.

All the details about this release are available in the release announcement, so let’s just walk through a number highlights:

  • Hop Server now supports SSL, projects and environments and asynchronous web services for long-running pipelines and workflows. There also is a new Hop Server Status transform.

  • the Docker image now supports optionally supports projects and environments, has additional logging information and status code improvements.

  • Apache Beam has been upgraded to 2.35.0 with support for Apache Spark 2.35.0 and Apache Flink 1.13.5. Apache Beam on Google Cloud Dataflow now supports service accounts and DataflowServiceOptions, which pass various options through if they’re not available in the GUI

  • new transform plugins:

    • Hop Server Status: retrieves a lot of server and operating system metrics from one of your Hop Servers.

    • Apache Tika Input parses files in all sorts of formats and extracts the text content as well as available metadata it can extract.

    • Metadata Input gives you access to the Hop Metadata items in the current project. It outputs all the metadata objects of all types unless one or more types are filtered.

    • Neo4j Graph Output now supports models with multiple relationships between two nodes, models with multiple node labels and models with self-relationships

  • Log4j completely removed

Apache Beam was updated to version 2.35.0 in Hop 1.1.0


With the busy start of the year running up to the Hop 1.1.0, the Apache Hop community hasn’t had a lot of time to work on spectacular new features since the Hop 1.1.0 release.

A couple of items worth highlighting:

  • the Apache Kafka have been getting quite a bit of attention in code hardening and robustness. Expect some additional functionality in this area soon.

  • an Avro Encode transform is work in progress

  • the Hop 2.0 branch now builds with Java 11. Follow progress on the Hop build server.

  • Hop now support ARM on Linux and in the Docker container


new Contributions

With the increased Apache Hop visibility after the graduation and the 1.1.0 release, we’ve seen a significant uptick in the number of forks of the Hop github code repository and contributions. We’ll work on updates statistics on community interaction and contributions soon.

A couple of notable new contributions are SonarCube code cleanup and fixes, Brazilian Portuguese translations and a new Hop web services in Docker tutorial. A huge thank you to everyone who contributed!

New Committers

The Apache Hop welcomed two new committers in January:

  • Yu-Jui (Ray) Chang: Ray started picking up small JIRA tickets months ago and has since then grown to become a valuable member of the Hop development team.

  • Ricardo Gouvea: started the Hop community in Brazil and has been very active in evangelising Hop in Brazil and in Portuguese. Ricardo is building a lot of hands-on Hop experience and provides lots of suggestions and feedback.

the Apache Hop Community in numbers

The Hop community continues to grow:

  • chat: 275 registered members (up from 256) join

Check out the complete list of committers and contributors.

Without community contribution, Hop is just a coding club! Please feel free to join, participate in the discussion, test, file bug tickets on the software or documentation, …​ Contributing is a lot more than writing code.

Check out our contribution guides and Code of Conduct to find out more.
