[Cassandra Wiki] Update of "ReadRepair" by JonathanEllis

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.

The "ReadRepair" page has been changed by JonathanEllis.
http://wiki.apache.org/cassandra/ReadRepair

--------------------------------------------------

New page:
Read repair means that when a query is made against a given key, we perform that query against all the replicas of the key.  If a low !ConsistencyLevel was specified, this is done in the background after returning the data from the closest replica to the client; otherwise, it is done before returning the data.

This means that in almost all cases, at most the first instance of a query will return old data.
