What's New in Confluent Platform 5.5
Confluent Platform 5.5 introduces several enhancements, including support for protobuf and json in the schema registry, improved connectivity for non-Java clients with exactly-once semantics, and the ksqlDB flow view for better application management. The new features aim to make event streaming more accessible and efficient for developers, with a focus on multi-language development and ease of use through enhanced admin functions. Overall, the update strengthens the ecosystem with rich pre-built tools and increased operational flexibility.
