*7. Error codes
0x1200 Read_timeout: Timeout exception during a read request. The rest of the ERROR message body will be <cl><received><blockfor><data_present> where: <cl> is the consistency level of the query having triggered the exception. <received> is an int representing the number of nodes having answered the request. <blockfor> is the number of replica whose response is required to achieve <cl>. Please note that it is possible to have <received> >= <blockfor> if <data_present> is false. And also in the (unlikely) case were <cl> is achieved but the coordinator node timeout while waiting for read-repair acknowledgement. <data_present> is a single byte. If its value is 0, it means the replica that was asked for data has not responded. Otherwise, the value is != 0.
