Terminates a filter chain in a ServiceFactory.
Terminates a filter chain in a ServiceFactory. For example,
myFilter.andThen(myServiceFactory)
a service factory that takes the output request type and the input response type.
Terminates a filter chain in a Service.
Chains a series of filters together:
Chains a series of filters together:
myModularService = handleExceptions.andThen(thrift2Pojo.andThen(parseString))
another filter to follow after this one
synchronously thrown exceptions in the underlying service are automatically lifted into Future.exception.
Conditionally propagates requests down the filter chain.
Conditionally propagates requests down the filter chain. This may useful if you are statically wiring together filter chains based on a configuration file, for instance.

A com.twitter.finagle.Filter that rate limits requests to a fixed rate over time by using the com.twitter.concurrent.AsyncMeter implementation. It can be used for slowing down access to throttled resources. Requests that cannot be enqueued to await a permit are failed immediately with a com.twitter.finagle.Failure that signals that the work was never done, so it's safe to reenqueue.
NOTE: If you're just trying not to be overwhelmed, you almost certainly want to use com.twitter.finagle.filter.RequestSemaphoreFilter instead, because RequestMeterFilter doesn't work well with "real" resources that are sometimes faster or slower (like a service that you're depending on that sometimes slows when it takes bursty traffic). This is better for resources that are artificially bounded, like a rate-limited API.
