An electronic mail system with a methodology providing distributed message storage and processing is described. In particular, this methodology breaks up how the individual components of message data are stored. Message data itself is broken up into two parts: a metadata (mutable) portion, and an immutable portion. The metadata portion represents that part of the message data that may change over time. This includes message status flags (e.g., the IMAP “message deleted” flag) and the message's position within a particular message folder, among other information. The immutable portion, which comprises the bulk of electronic mail data (namely, the message itself), once stored is never edited. Immutable data is written f+1 times on as many unique servers, to tolerate f number of server failures using Lampson's stable storage algorithm. The metadata portion is stored 2f+1 times on as many unique servers to tolerate f number of server failures using quorum voting. Once the message has been stored once, instead of being copied, its location is passed around by reference. The system utilizes a two-tier architecture. One tier consists of servers which store message metadata and immutable data, the Data Servers, and servers that operating upon those data, the Access Servers. Message store integrity is maintained in the event of server failure and as the set of Data Servers changes. In the latter case, I / O and storage workloads are dynamically redistributed across Data Servers in an efficient way.

A system and method for efficiently implementing a local or distributed file system is disclosed. The system may include a distributed virtual file system (“dVFS”) that utilizes a persistent intent log (“PIL”) to record transactions to be applied to the file system. The PIL is preferably implemented in stable storage, so that a logical operation may be considered complete as soon as the log record has been made stable. This allows the dVFS to continue immediately, without waiting for the operation to be applied to a local or real file system. The dVFS may further incorporate replication to one or more remote file systems as an integral facility.

This invention concerns a database computer system and method for making applications recoverable from system crashes. The application state (i.e., address space) is treated as a single object which can be atomically flushed in a manner akin to flushing individual pages in database recovery techniques. To enable this monolithic treatment of the application, executions performed by the application are mapped to logical loggable operations that can be posted to the stable log. Any modifications to the application state are accumulated and the application state is periodically flushed to stable storage using an atomic procedure. The application recovery integrates with database recovery, and effectively eliminates or at least substantially reduces the need for check pointing applications. In addition, optimization techniques are described to make the read, write, and recovery phases more efficient. Atomic flush sets, whether generated from cyclic flush dependencies or otherwise, can be broken apart. This enables an ordered flushing sequence of first flushing a first object and then flushing a second object, rather than having to flush both the first and second objects simultaneously and atomically.

Method, apparatus and computer program product for fault recovery in a distributed stateful publish-subscribe system. The system includes the capability of recovering from failures that may occur when a stateful publish-subscribe service is implemented on an overlay network.
