Updates on Spring Cloud Stream 4.0.0 Schema Registry Support

Engineering | Soby Chacko | November 10, 2022 | ...

This blog gives an update on the Schema Registry support that is part of Spring Cloud Stream version 4.0.x.

Many enterprises use a schema registry for schema evolution use cases, such as the Confluent Schema Registry. Starting with version 1.1.x of Spring Cloud Stream until 3.0.0, we provided a schema registry server and AVRO-based schema registry client converters that can reconcile the schema from the schema registry server. Spring Cloud Stream version 3.0.0 moved the Schema Registry components into a top-level spring-cloud project, and Spring Cloud Stream included those in its BOM for the…

This Week in Spring - November 8th, 2022

Engineering | Josh Long | November 08, 2022 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring! I've been busy this last week! I've been visiting with customers and talking to the community here in South East Asia. I was in Malaysia last week, and now I'm in Bangkok, Thailand. I'm near the end of my time here in SE Asia, which makes me sad. I'm dearly going to miss the food and the weather, but time waits for no person, and it's almost time to go home.

And with time comes a jam-packed roster of new things we can read and learn from. So, without further ado, let's dive right into it!
