* Package name : python-taskflow Version : 0.1.1 Upstream Author : Taskflow Development Mailing List <taskflow-...@lists.launchpad.net> * URL : https://github.com/stackforge/taskflow * License : Apache-2.0 Programming Lang: Python Description : A library to complete workflows/tasks in HA manner Taskflow is a Python library for OpenStack that helps make task execution easy, consistent, and reliable. It allows the creation of lightweight task objects and/or functions that are combined together into flows (aka: workflows). It includes engines for running these flows in a manner that can be stopped, resumed, and safely reverted. Projects implemented using the Taskflow library enjoy added state resiliency, fault tolerance and simplified crash recovery. Think of it as a way to protect an action, similar to the way transactions protect operations in a RDBMS. If a manager process is terminated while an action was in progress, there is a risk that unprotected code would leave the system in a degraded or inconsistent state. With Taskflow, interrupted actions may be resumed or rolled back automatically when a manager process is resumed. .. Using Taskflow to organize actions into lightweight task objects also makes atomic code sequences easily testable (since a task does one and only one thing). A flow facilitates the execution of a defined sequence of ordered tasks (and imposes constraints on the way an engine can run those tasks). A flow is a structure (a set of tasks linked together), so it allows the calling code and the workflow to be disconnected so flows can be reused. Taskflow provides a few mechanisms for structuring & running flows and lets the developer pick and choose which one will work for their needs. -- To UNSUBSCRIBE, email to debian-wnpp-requ...@lists.debian.org with a subject of "unsubscribe".
