多租户系统中租户控制队列并发

Question

I have a multi-tenancy system and need to guarantee FIFO (first-in-first-out) processing of queued messages by tenant, ie each tenant would get its own MaxConcurrentCalls = 1 .

To be done in Azure and technology not fixed.

I know this could be achieved by creating a separate WebJob for each tenant, but that limits scalability.

Are there any other ways to achieve such a behaviour?

Answer 1

Since you mentioned Service Bus, I suggest

• Use Service Bus Queues or Topics with Sessions enabled
• Assign session identifiers based on tenant ID

This way you should be able to process messages one-by-one and in-order per tenant, but multiple tenants in parallel.
