Expecting the Unexpected

At Qixxit, we combine bus, train and flight options into a single route, allowing customers to book through a single platform. This requires communication with a lot of 3rd parties which can fail for a variety of reasons. Because this is a critical process, it is important to have full traceability to recover from potential failures.

We will look at how traceability might falter, and why this matters, a strategy to regain traceability and recoverability, and how we derive a pattern to use in our system.

OBJECTIVES

This talk aims to raise awareness of the failure scenarios of distributed transactions and common strategies to trace them in a general pattern, not specific to a certain domain.

AUDIENCE

The talk addresses those interested in distributed transactions (e.g., in an ecommerce system).
