kestel - 分布式消息隊列系統

kestel是一個簡單，分布式消息隊列系統。

特性：

• fast

  It runs on the JVM so it can take advantage of the hard work people have put into java performance.

• small

  Currently about 2500 lines of scala, because it relies on Netty (a rough equivalent of Danger's ziggurat or Ruby's EventMachine) -- and because Scala is extremely expressive.

• durable

  Queues are stored in memory for speed, but logged into a journal on disk so that servers can be shutdown or moved without losing any data.

• reliable

  A client can ask to "tentatively" fetch an item from a queue, and if that client disconnects from kestrel before confirming ownership of the item, the item is handed to another client. In this way, crashing clients don't cause lost messages.
