When serving heterogeneous datasets (e.g. data with a type key), if could be very useful to be able to retrieve all unique key values.

Examples:

  1. Get all unique keys
>>> /unique_endpoint
{
    'type': ['reflectance', 'index', 'composite'],
    'date': ['20180101', '20180101_20180201'],
    'id': ['1', '2', '3']
}
  1. Get keys valid for reflectances
>>> /unique_endpoint?type=reflectance
{
    'type': ['reflectance'],
    'date': ['20180101'],
    'id': ['1']
}
  1. Get all data for a specific date
>>> /unique_endpoint?date=20180101
{
    'type': ['reflectance', 'index'],
    'date': ['20180101'],
    'id': ['1', '2']
}

An alternative could be to find a better abstraction / separation between datasets.
