As its primary feature, Data Access Gateway 5.0 enables support for the Apache Kafka Wire Protocol Service. Apache Kafka Wire Protocol Service makes it possible for Apache Kafka clients written in any programming language to access topics in HPE Ezmeral Data Fabric Streams. For more information about the new service, see Apache Kafka Wire Protocol Service.

Only Data Access Gateway 5.0 can be used with release 7.1.0. Data Access Gateway 5.0 supports FIPS and non-FIPS installations. See FIPS Support for Ecosystem Components.

The HPE Ezmeral Data Fabric Data Access Gateway is included in EEP repositories beginning with EEP 5.0.0. The Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the data-fabric cluster.
