[FlightSQL] Structured/Serialized representation of query (like JSON) rather than SQL string possible?

[Gavin Ray]

Hiya,

I am drafting a proposal for a way to enable services to express data
compute operations to each other.

However I think it'll be difficult to get buy-in if the only representation
for queries is as SQL strings.

Is there any kind of lower-level API that can be used to express operations?

IE instead of "SELECT name FROM user"

A structured representation like:
{
  "op": "query",
  "schema": "user",
  "project": ["name"]
}

Or maybe this is a bad idea/doesn't make sense?

Thank you =)
