Reactive Support in Spring for Apache Pulsar Will Be Discontinued

TL;DR: We’ve decided to discontinue the Reactive support within the Spring for Apache Pulsar project.

Our team regularly evaluates our project portfolio with long-term sustainability in mind. When adoption declines, we thoughtfully retire projects / functionality to focus our efforts where the community needs them most. Based on an assessment of adoption metrics, download trends, and project activity, we’ve decided to remove the Reactive support within the project.

What does this mean for our users?

  • The spring-pulsar-reactive module will be removed from all future releases, starting with Spring for Apache Pulsar 2.0.0.

  • Spring Boot support of the Spring for Apache Pulsar Reactive components will be removed from all future releases of Spring Boot, starting with Spring Boot 4.0.0.

We remain committed to the continued development of the Spring for Apache Pulsar project.

We sincerely thank everyone who has contributed to Reactive support in Spring for Apache Pulsar over the years. If you have any questions or concerns, feel free to reach out through the relevant GitHub repositories or leave a comment below.

Thank you,

Spring for Apache Pulsar Team
