As I am going through few articles on Cassandra, it says Cassandra achieves highest throughput among various No SQL solutions but at the cost of high read and write latency. I have a basic question here - (If my understanding is right) Latency means the time taken to accept input, process and respond back. If Latency is more how come the Throughput is high?

Hi,

I have a basic question here - (If = my understanding is right) Latency means the time taken to accept input, pr= ocess and respond back. If Latency is more how come the Throughput is high?=
