Detailed Description

Fail-fast when tasks are consistently failing.

A missbehaving dependency might take a long time to respond. When many operations depend on it the slowdown can be propagated to the rest of the system.

The Circuitbreaker uses an algorithm (implemented in the strategy) to determine when to stop contacting the dependency and just assume a failure.

This keeps limit the performance impact a dependency can cause to the whole system.
