Asynchronous
is an option for WolframAlpha that determines whether to use the asynchronous features of the Wolfram|Alpha API.
Details

- With Asynchronous->False, the WolframAlpha function retrieves all pod data from the Wolfram|Alpha server in a single transaction.
- With Asynchronous->True, the WolframAlpha function sets the "async=true" flag in the API. An initial block of content is retrieved from the Wolfram|Alpha servers, which may contain placeholders. The placeholders are filled by subsequent, parallel calls to Import. The WolframAlpha function returns once all of the calls to Import have been resolved.
- WolframAlpha["query","FullOutput",Asynchronous->All] retrieves the initial block of content identically to Asynchronous->True. The function then immediately returns, displaying Dynamic content that populates over time with subsequent calls to Import.
- Asynchronous->All for other formats is equivalent to Asynchronous->True.
