List layers API

Is something like this possible in dynamo without traversing the entire table? I don't think you can do a query for "unique" without checking every record. Maybe a secondary table that lists the tables?

[tmcw]

Try Select: 'COUNT'?

notes:

• we will probably need a secondary datastore past a couple thousand layers
• for now, query the layer attribute for all records, then return unique

This is requiring an update in dyno mapbox/dyno#2. Currently, dyno does not allow for you to send a default query with no constraints. If you try, it returns (or some variation, depending on how you try to get around it):

Query condition missed key schema element layer.

@morganherlocker you cant do a query with no constraints, a hash key is required.You'll want scan.

Closing for now. Will reopen if this implementation becomes an issue.
