HPE Ezmeral Data Fabric Event Store Python Applications
As of MapR 5.2.1, you can create python applications for HPE Ezmeral Data Fabric Event Store using the HPE Ezmeral Data Fabric Event Store Python client. The HPE Ezmeral Data Fabric Event Store Python client is a binding for librdkafka and the HPE Ezmeral Data Fabric Event Store C Client is a distribution of librdkafka that works with HPE Ezmeral Data Fabric Event Store.
The HPE Ezmeral Data Fabric Event Store Python client is available in a Ecosystem Pack (MEP) starting with MEP 3.0.
The following Apache Kafka librdkafka versions are supported:
| MapR release | MEP Release | Kafka librdkafka version |
|---|---|---|
| As of MapR 6.0.1 | As of 5.0 | 0.11.3 |
| As of MapR 5.2.1 through 6.0.0 | As of 3.0 | 0.9.0 |
Note: Because the HPE Ezmeral Data Fabric Event Store Python Client is dependent on the HPE Ezmeral Data Fabric Event Store C Client, the HPE Ezmeral Data Fabric Event Store C
Client must be configured before using the HPE Ezmeral Data Fabric Event Store Python Client.
When developing and running HPE Ezmeral Data Fabric Event Store Python applications, note the following points:
- You can create producers and high-level consumers. Low-level consumers are not supported.
- Consuming or producing topics in a Kafka cluster is not supported.
- HPE Ezmeral Data Fabric Event Store offset values start at 1, not 0.
- MapR security is supported including ACLs and ACEs for authorization. The unique Kafka security features that are part of Apache Kafka are not supported. See Security for more information about MapR security features.
- User impersonation is not supported.
