Here is the link to Presto: http://prestodb.github.io/
Yes, it’s definitely a distributed SQL query engine for big data. If you are expecting a lot of different values to come in, then you’re only trying to add a value to the existing records? I don’t understand where the data is coming from. This seems straightforward. I must be missing some aspect to it still.

Secondly, is Presto a distributed system ? Thanks and Regards, Goutham.

It looks like you have to provide the value before Cassandra, maybe through your application or something in the stream before Cassandra, or add it after Cassandra or use something like Spark to process it.
