New in This Release
- Data Access Gateway version 6.1 supports fully distributed Kafka Wire Protocol
service.
In previous versions of Data Access Gateway, only the controller is assigned the partition leader of all topic partitions. In Data Access Gateway version 6.1, topic partitions are distributed evenly among all Data Access Gateway nodes, improving overall cluster throughput.
- Added support for Python, Go, Scala, C Kafka, and Node.js clients.
Data Access Gateway 6.1 can be used with core 7.4.0, 7.3.0, and 7.2.0. However, Kafka Wire Service protocol is only available for Data Access Gateway 6.1 on core 7.4.0. When using Data Access Gateway 6.1 with core 7.3.0 or 7.2.0, Kafka Wire Protocol service is disabled. Data Access Gateway 6.1 supports FIPS and non-FIPS installations. See FIPS Support for Ecosystem Components.
