How are partitions assigned in a consumer group?

This is based on the partition assignment strategy configuration, an important note here is that this is a topic-specific configuration. It can only be used to describe the strategy used to assign partitions to a specific consumer group.

The default strategy is called the RangeAssignor strategy. In this strategy, we divide the number of partitions over the number of consumer instances, and assign one by one. If the division does not result in a nice round number, the first few consumer instances are assigned more partitions.

Example

Suppose there are two consumers C₀ and C₁, two topics t₀ and t₁, and each topic has 3 partitions, resulting in the following partitions: t₀p₀, t₀p₁, t₀p₂, t₁p₀, t₁p₁, and t₁p₂

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
