Subject Can a Select Count(*) Affect Writes in Cassandra?
Date Thu, 10 Nov 2016 08:36:59 GMT
Hi There!

I'm using C* 2.0.14.
I experienced a scenario where a "select count(*)" that ran every minute on
a table with practically no results limit (yes, this should definitely be
avoided), caused a huge increase in Cassandra writes to around 150 thousand
writes per second for that particular table.

Can anyone explain this behavior? Why would a Select query significantly
increase write count in Cassandra?

Thanks!
