I have a generic question which is not related to this PR. I observe there are bunch of pre-processing logic for a request: * authz/authn * admission control (e.g. disallow user to create new segments if existing number of segments exceed a threshold. We don't have this logic yet, but it's useful and may be added in future) * request validation (validate schema, etc) * request rewriting( e.g. this PR rewrite request by normalizing LHS and RHS for numerical types) * log and audit. Now all those logic are put into BrokerRequestHandler, which is a little messy and hard to maintain. Ideally, we should use HTTP middleware to decouple those pre-processing/post-processing logic from the actual query processing logic. Most web framework provide such a HTTP middleware mechanism out of box, the HTTP library ***JAX-RS*** we use also provide similar mechanism: [Filters and Interceptors](https://dennis-xlc.gitbooks.io/restful-java-with-jax-rs-2-0-2rd-edition/content/en/part1/chapter12/filters_and_interceptors.html) cc @mcvsubbu @siddharthteotia @Jackie-Jiang -- This is an automated message from the Apache Git Service.
