Thank you for your reponse

 We monitored the write/read throughput through the Cassandra cluster via 
 JMX. There was little read throughput before March 6. From March 6, the 
 write throughput increased, but the read throughput suddenly increased 
 sharply. Do anyone know why this happens?

Well it’s hard to say unless you’re more precise with what JMX emitted metric 
you’re graphing, but yes, there are read metrics that will increase if people 
read the data

No I didn’t

Do you mean that this read throughput value comes out because somebody actually 
reads the data?

[Jeff Jirsa]

I presume you’re asking because you don’t think you’re doing reads. Did you 
start doing counter writes?
