Subject consistency ONE and "null"
Date Wed, 06 Apr 2011 23:09:38 GMT

Let's say you have RF of 3 and a write was written to 2 nodes.  1 was not written because
the node had a network hiccup (but came back online again).

My question is, if you are reading a key with a CL of ONE,  and you happen to land on that
node that didn't get the write, will the read fail immediately?

Or, would read repair check the other replicas and fetch the correct data from the other node(s)?

Secondly, is read repair done according to the consistency level, or is read repair an independent
configuration setting that can be turned on/off.

There was a recent thread about a different variation of my question, but went into very technical
details, so I didn't want to hijack that thread.
