finagle-clojure.filter

Wrapper around com.twitter.finagle.Filter. Filters are like middleware and can be used to add funcionality common to many Services, like instrumentation or backpressure.

Filters are composed with other Filters or Services resulting in a Service. Use and-then or chain to compose Filters & Services together.

Arguments:

  • filter: a Filter.
  • next: a Filter or Service.
