Dreaming for Errors: Logging, Handling, and Integrations

Don’t expect your data to import completely every time; if you’re lucky, some of it might occasionally.

It is crucial to anticipate problems while building or programming your integration application and, as a result, construct your programme with the chance of errors at the forefront of what you’re attempting to achieve. Actually, errors are perhaps even more important than the data itself.

This blog post outlines our top recommendations for creating integrated error handling and logging.

Design Pattern – The Layered Approach to Error Handling

In a previous role, I had the disagreeable responsibility of maintaining a number of a colleague’s badly constructed import scripts. After each version, I would refactor a certain piece of the programme for my own mental health, and I also maintained the many integrations I had developed. As the integration handled failures over time, each import eventually developed a standard structure.

The pattern that emerged had a three or four layer structure, with each layer responsible for its own error handling tasks.

Atomic transaction:

This layer, which is the innermost one in your integration, is in charge of overseeing a single “atomic” transaction. This layer is the one that cancels or reverses any partially written transaction in the event of failure.

Transaction handler:

The ‘atomic’ transaction handler is effectively called by the transaction handler, which is essentially a loop. This layer must choose whether to continue with the current transaction or abort when the atomic handler raises an error.

Task handler (optional):

The task handler controls the handling of exceptional and non-exceptional data when your integration interacts with any number of endpoints. If a transaction is successful, it must be submitted to the next endpoint; however, if it

Entry point:

A layer of your application’s structure. It is in charge of:
[inner-list number=”1″] double=”1″ inner-list-el creation of the processing report or end user log. [/inner-list-el] double=”1″ inner-list-el identifying and recording any unexpected or severe errors. [/inner-list-el] [/inner-list]

It should go without saying that no unfinished transactions, database entries, or files should ever be left behind when an error occurs during your automatic integration.
