However, these are logically distinct, which is why the Thrift interface is oriented around accessing one !ColumnFamily per key at a time. (TODO given this, is the following JSON more confusing than helpful?) - A JSON representation of the key -> column families -> column structure is + A JSON representation of the rowkey -> column families -> column structure is {{{ { - "mccv":{ + "row_key1":{ "Users":{ "emailAddress":{"name":"emailAddress", "value":"f...@bar.com"}, "webSite":{"name":"webSite", "value":"http://bar.com"} @@ -65, +65 @@ "visits":{"name":"visits", "value":"243"} } }, - "user2":{ + "row_key2":{ "Users":{ "emailAddress":{"name":"emailAddress", "value":"us...@bar.com"}, "twitter":{"name":"twitter", "value":"user2"}
