Question

I’m trying to use cassandra to store view counts that i am parsing from some log files

Is there a way to do views => views + 343 or something along those lines? i don’t want to have to query first because that will slow down my script quite a bit.

Answer 1

Cassandra support native counters; you will need to declare the default validation class (ie the default value type) as CounterColumnType:

create column family counterCF with default_validation_class=CounterColumnType;

Then you should be able to do CQL operations like:

UPDATE counterCF SET X = X + N WHERE key = K;
