Goals we set out with

● smart broker.id assignment.● preservation of broker placement (through

constraints and/or new features).● ability to-do configuration changes.● rolling restarts (for things like configuration

changes).● scaling the cluster up and down with

automatic, programmatic and manual options.● smart partition assignment via constraints visa

vi roles, resources and attributes.

Scheduler● Provides the operational automation for a Kafka

Cluster.● Manages the changes to the broker's

configuration. ● Exposes a REST API for the CLI to use or any other

client.● Runs on Marathon for high availability.

Executor● The executor interacts with the kafka broker as an

intermediary to the scheduler

Scheduler & Executor

CLI & REST API

● scheduler - starts the scheduler.● add - adds one more more brokers to the cluster.● update - changes resources, constraints or broker properties one or

more brokers.● remove - take a broker out of the cluster.● start - starts a broker up.● stop - this can either a graceful shutdown or will force kill it

(./kafka-mesos.sh help stop)● rebalance - allows you to rebalance a cluster either by selecting the

brokers or topics to rebalance. Manual assignment is still possible using the Apache Kafka project tools. Rebalance can also change the replication factor on a topic.

● help - ./kafka-mesos.sh help || ./kafka-mesos.sh help {command}
