I am reading data from cassandra table with the help of pyspark , and read consistency at cassandra level it is local_one . I am observing nodes are becoming unresponsive and sometimes throwing an error no replica is available . This is only happening when pyspark job is trying to read cassandra table .
I have below query:
as per my understanding read consistency local_one in this case read request should be served fast as only one closest replica needs to respond in this case . But is it possible cassandra node might be overloaded in case read consistency with local_one ?
