Hi,
 
First of all,the write latency of cassandra is not high(Read is high).
 
The high throughput is achieved through distributes read and write. 
 
Your doubt ( If Latency is more how come the Throughput is high ) is some what 
right if you put high consistency to both read and write.
 
You will get distributed abilities since it is not Master/Slave 
architecture(Like HBase).
 
 If  your consistency is lesser,then some nodes out of all replica nodes are 
free and will be used for another read/write . [ Think you are using 
multithreaded 
application ]
 
Thanks & Regards

Subject: Throughput Vs Latency


Hi,


I am new to No SQL (and Cassandra). 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?


Thanks

Ajay
