Asynchronous Operations¶

Asynchronous operations are the practice of processing requests in the background, rather than blocking the response to the client until the operation is complete.

If client application:

• needs one big result at the end
• nothing meaningful can be provided before the entire operation finishes

Examples of such operations can be:

• running a big report requiring our system to talk to many databases
• big data analysis that scans a lot of records/log files
• compression of network model data

The pattern used for these situtations is an Asynchrononous API A client application receives a response immediately without having to wait for the final result.

That response includes some kind of identifier that allows:

• to track the progress and status of the operation
• receive the final result
