the pdf at the design doc https://issues.apache.org/jira/secure/attachment/12459754/Partitionedcountersdesigndoc.pdf
does say so: page 2 "- strongly consistent read: requires consistency level ALL. (QUORUM is insufficient.) " but the wiki http://wiki.apache.org/cassandra/Counters gave a code example: rv = client.get_counter('key1', ColumnPath(column_family='Counter1', column='c1'), ConsistencyLevel.ONE) is one of them wrong? Thanks Yang
