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.

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. As of version 6.1, Data Access Gateway supports REST endpoints for HPE Ezmeral Data Fabric Binary and JSON tables (See Administering Tables), lightweight Ojai clients for HPE Ezmeral Data Fabric JSON tables (see Using the Python OJAI Client and HPE Ezmeral Data Fabric Database and Apps), and Apache Kafka clients for HPE Ezmeral Data Fabric Streams (see Administering Streams).
