> Fast Cassandra Input Validator
> ------------------------------
>
> Key: CASSSIDECAR-361
> URL: https://issues.apache.org/jira/browse/CASSSIDECAR-361
> Project: Sidecar for Apache Cassandra
> Issue Type: Improvement
> Components: Performance, Rest API
> Reporter: Francisco Guerrero
> Assignee: Francisco Guerrero
> Priority: Normal
> Time Spent: 20m
> Remaining Estimate: 0h
>
> I'm proposing a new implementation of the Cassandra input validator. Our
> current implementation is based on regular expressions. In the proposed
> implementation it optimizes by not using any regular expression.
> A JMH benchmark shows a 15X speedup in the throughput in the optimized
> implementation. This is important because these validations sit at the
> beginning of every request, and when Sidecar is handling thousands of
> requests per second on a single instance, any improvement is significant.
