1. class ServiceFactoryCache[Key, Req, Rep] extends Closable

   

   A "read-through" cache of service factories.

   A "read-through" cache of service factories.

   Eviction is based on cache size and idle time:

   1. When the cache is full, a miss evicts the most idle factory. When no underlying factories are idle, a one-shot factory is created. This doesn't necessarily guarantee good performance: one-shots could be created constantly for a hot cache key, but should work well when there are a few hot keys.

   2. Periodically evict factories that are idle for at least one TTI (time-to-idle) period. An idle factory could remain in the cache for up to (TTI * 2) minutes, with the caveat that we never expire the last, least-idle entry.

2. class StatsFactoryWrapper[Req, Rep] extends ServiceFactoryProxy[Req, Rep]

   

   A com.twitter.finagle.ServiceFactoryProxy that tracks statistics on com.twitter.finagle.Service creation failures and service acquisition latency.

3. class TimeoutFactory[Req, Rep] extends ServiceFactoryProxy[Req, Rep]

   

   A factory wrapper that times out the service acquisition after the given time.

   A factory wrapper that times out the service acquisition after the given time.
