Expiry Callbacks for Couchbase Server

TTL's and Expiry Notification

Couchbase includes a TTL (Time To Live) as part of the meta data fields for each document.  All of the client SDK's includes support for setting/querying/touching this value.   The value is set as the "number of seconds a document should live" for documents that are to expire in 30 days or less.  For values longer than 30 days a unix epoch time value must be passed.  TTL's are often used in high performance session stores and caching applications.

PHP SDK 2.0.0 Developer Preview

Over the past few months, the SDK development team has been working on defining a new interface for interacting with the SDKs, dubbed SDK 2.0 (not directly related to PHP SDK 2.0.0 which merely happens to implement a large portion of that specification). The existing SDKs were all designed around existing interfaces that were targeted towards the memcached project, and as such were very cache oriented and no longer effectively reflected the more document oriented nature of Couchbase Server 2.0. As such, we set out to define a new, more modern interface which would better model those traits.
