Workflow: library for transparent execution of interruptible computations

[ bsd3, control, library, workflow ] [ Propose Tags ]

Transparent support for interruptible computations. A workflow can be seen as a persistent thread that executes any monadic computation. Therefore, it can be used in very time consuming computations such are CPU intensive calculations or procedures that are most of the time waiting for the action of a process or an user, that are prone to comunication failures, timeouts or shutdowns.

The computantion can be restarted at the interrupted point thanks to its logged state in permanent storage. Besides that, the package also provides other services associated to workflows

New in this release,

  • 0.5.8.2 minor changes for the MFlow package

  • 0.5.8.1 solved a bug that caused a "casting failure"

  • 0.5.8:

  • registerType is no longer needed

  • Configurable state persistence (for example, in databases) . Default in files

  • Added Data.Binary serialization (Use Control.Workflow.Binary) besides Text serialization (Control.Wokflow.Text)

  • New simpler and more intuitive workflow primitives with excepion handling

  • Instances of classes in Control.Concurrent.MonadIO, MonadCatchIO

  • An EDSL of workflow patterns. To express bifurcations, confluences, timeouts etc

  • References to workflow objects, that can be accessed externally: WFRef's

Previous versions:

  • Persisten communications facilities trough persistent data objects, inspection of workflow states , persistent queues, persistent timeouts and, new in this release, References to internal workflow objects WFRef's

  • workflow management and monitoring, view workflow history and intermediate results.
