Subject Re: consistency ONE and "null"

as I understand, the read repair is a background task triggered by the read
request, but once the consistency requirement has been met you will be given
a response.

the coordinator at CL.ONE is allowed to return your responce once it has one
response (empty or not) from any replica. if the first response is empty,
you get null
