      • tableSizeInBytes

        public long tableSizeInBytes​(java.lang.String keyspace,
                             java.lang.String table,
                             java.lang.String datacenter)
        Returns the total used space for table across the datacenter. If only a subset of instances succeeds gathering the table size, the method will normalize the table size to the number of instances. If all the instances fail to retrieve the table size, this method will throw an exception.
        Specified by:
        tableSizeInBytes in interface org.apache.cassandra.spark.data.TableSizeProvider
        Parameters:
        keyspace - the keyspace where the table lives
        table - the table to get the size from
        datacenter - the datacenter
        Returns:
        the total used space for the table across the datacenter
        Throws:
        java.lang.RuntimeException - when all the instances fail to retrieve the table size
