Azure的角色间同步 [英] Azure inter-role synchronization
问题描述
我想知道在同步运行相同角色的多个实例，湛蓝的最佳实践。
更多precisely，我想prevent几个辅助角色在同一工作单位上工作。
I was wondering about the best practices in synchronizing multiple azure instances that run the same role. More precisely, I want to prevent several worker roles to work on the same work-unit.
Azure的队列似乎并没有帮助这个问题。
一种选择是使用带有锁和存储过程SQL表;但是在Azure中使用SQL同步似乎有点尴尬。
Azure queues do not seem to help on this matter. One option is to use an sql table with locks and stored procedures; but using sql synchronization in Azure seems a bit awkward.
任何想法？
编辑，我详细的（但简单的问题）如下：
Edit, my detailed(but simplified problem) is as follows:
- 有 N 目标。
- 工作的单位必须在每个目标在指定的时间间隔做（说30秒 - 但它是每个目标不同） 。
- 我的 M 人员（在美国举行的 ^ h 实例）。
- 处理工作单元可能需要10秒到1小时之间的任何东西。
- There are n targets.
- A unit of work must be done on each target at a specified interval (say 30 seconds - but it is different for each target).
- I have m workers (hosted in h instances).
- Processing a unit of work could take anything between 10 seconds and 1 hour.
的想法是，我有一个调度这让工作单位在Azure的队列，每个的 M 工人将阅读这些并处理它们。
The idea is that I have a scheduler that puts units of work in an Azure queue, and each of the m workers will read these and process them.
问题：
- worker1 在开始工作的 1单元（这是关于目标1 ） - 此人会需要很长时间，例如10分
- 经过30秒
- 调度提出另一个单位工作，为的目标1 ，说的 unit13
- worker2 开始工作的 unit13 ，对同一目标1 - 不好
- worker1 starts working on unit1 (which is regarding target1) - this one will take long, say 10 minutes
- 30 seconds pass
- the scheduler puts another unit of work for target1, say unit13
- worker2 starts working on unit13, against the same target1 - not good
我有一些想法，但他们似乎并没有的阴天的不够，所以我很有兴趣看你申请什么方案来解决这个问题。
I have some ideas, but they don't seem cloudy enough, so I am interested to see what solutions would you apply for this problem.
