Offset vs Skip #3

Closed cayuu closed 9 years ago

cayuu commented 9 years ago

There is currently no mechanism to differentiate an offset by id or by a number to skip.

Currently the spec only provides for: 

{offset: 10}

This is not clear whether we mean to skip 10 records or to start at record id "10".

One option is to always treat numbers as 'skip' and strings as 'start at id'. However, that fails if the system is storing ids as numbers. offset: "10" will mean searching for id:"10" and will not find id:10. Options:

  1. Overload string offset (eg. offset: "10" means id:"10", offset:"+10" means id:10)
  2. Create a new field. offset for ids and skip for numbers
  3. Offset as object: offset: {skip:25} and offset: {id:25}

Last option is intuitively most appealing.

Could also:

offset: 25 = skip offset: {id: 25}

To simplify the default?

cayuu commented 9 years ago

Worth noting that {id:25} looks a lot like a simple match object. This could actually facilitate offsetByArbitrary.
