有状态服务的Azure Service Fabric自动缩放

Question

Read this article on autoscaling in Service Fabric. Now I am wondering about how this works with stateful services. It is possible to add more partitions but what about redistributing the data?

Example:

2 Partitions with range 0-99 Due to autoscaling we get a 3rd partition, what happens with data in partition 1 and 2?

Answer 1

The partition scheme & range you have described cannot be autoscaled.

• Named partition scheme must be used for the service.
• Partition names must be consecutive integer numbers, like "0", "1", ... First partition name must be "0".

Data in partition 1 & 2 would be unchanged in the event of a partition being added if the above conditions are satisfied.
