[jira] [Created] (CASSANDRA-21522) Allow setCompressedReadAheadBufferSizeInKb(0) to disable RAB

Nivy Kani created CASSANDRA-21522:
-------------------------------------

             Summary: Allow setCompressedReadAheadBufferSizeInKb(0) to disable RAB
                 Key: CASSANDRA-21522
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-21522
             Project: Apache Cassandra
          Issue Type: Bug
            Reporter: Nivy Kani
            Assignee: Nivy Kani


In DatabaseDescriptor:1132, the exception states: "compressed_read_ahead_buffer_size must be at least 256KiB (set to 0 to disable)". But, if an operator ever later tries to disable the buffer by following this message and setting sizeInKb to 0, setCompressedReadAheadBufferSizeInKb() will throw an error that sizeInKb < 256.
