Kafka-Utils

A suite of python tools to interact and manage Apache Kafka clusters. Kafka-Utils currently runs on python2.7.

Configuration

Kafka-Utils reads cluster configuration needed to access Kafka clusters from yaml files. Each cluster is identified by type and name. Multiple clusters of the same type should be listed in the same type.yaml file. The yaml files are read from $KAFKA_DISCOVERY_DIR, $HOME/.kafka_discovery and /etc/kafka_discovery, the former overrides the latter.

Sample configuration for sample_type cluster at /etc/kafka_discovery/sample_type.yaml

  clusters:
    cluster-1:
      broker_list:
        - "cluster-elb-1:9092"
      zookeeper: "11.11.11.111:2181,11.11.11.112:2181,11.11.11.113:2181/kafka-1"
    cluster-2:
      broker_list:
        - "cluster-elb-2:9092"
      zookeeper: "11.11.11.211:2181,11.11.11.212:2181,11.11.11.213:2181/kafka-2"
  local_config:
    cluster: cluster-1

Install

From PyPI:

    $ pip install kafka-utils

Kafka-Utils command-line interface

List all clusters
