if in cassandra cf, rowkey (a, b, c) , data highly skewed cardinality of being let's one. entire data reside on single node of cassandra cluster if replication factor 1?
also, if node down, exception get?
if have 1 partition key , rf 1 not able access data if node row hashes down. unavailable exception.
primary key ((a),b,c) or primary key (a,b,c) means a decides node data resides on.
primary key ((a,b),c) mean using composite key , combination of a , b deterimines node is.
primary key ((a,b,c)) means full combination of a, b, , c used decide correct node.
all of variables not in first set of inner parenthesis act clustering keys , determine sorted order of data within row not node row placed on.
