MapR Event Store For Apache Kafka Python Applications

As of MapR 5.2.1, you can create python applications for MapR Event Store For Apache Kafka using the MapR Event Store For Apache Kafka Python client. The MapR Event Store For Apache Kafka Python client is a binding for librdkafka and the MapR Event Store For Apache Kafka C Client is a distribution of librdkafka that works with MapR Event Store For Apache Kafka.

The MapR Event Store For Apache Kafka Python client is available in a MapR Expansion Pack (MEP) starting with MEP 3.0.

The following Apache Kafka librdkafka versions are supported:

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 MapR Event Store For Apache Kafka Python Client is dependent on the MapR Event Store For Apache Kafka C Client, the MapR Event Store For Apache Kafka C Client must be configured before using the MapR Event Store For Apache Kafka Python Client.
When developing and running MapR Event Store For Apache Kafka 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.
  • MapR Event Store For Apache Kafka 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.
