Query attribute/binding

[MerrionComputing]

Need to have a Query class which can be bound to a parameter on an Azure function with autoresolve properties for query name and unique identifier.

if the unique identifier is not set, use a GUID

This will create an event stream to use to orchestrate execution of the step(s) required to process the query.

Needs to be on a per Domain basis.

The main events / steps of processing a query would be:-

• Query created
• Parameter set
• Validations
• Classifications requested
• Projections requested
• Collations
• Response

[MerrionComputing]

Classifications needed:-

• Completed (this allows completed queries to be archives to other storage, for example)

Projections needed:-

• Output targets (as this may be changed while a query is running)

Query functions

• GetQueryState - Get the state of the given query instance
• CompareQueries - Compare the outcome of two query instances (for "what has changed" analysis)
