关于Solace订阅能否传入指定苹果类型列表的技术咨询

Nice question! You’re in luck—Solace has exactly what you need to avoid creating dozens of duplicate subscriptions: topic sets (using curly brace syntax).

Instead of trying to jam comma-separated values into a single topic segment, format your subscription like this:

produce/{gala,delicious,seedless}/seedless/color

Here’s how it works: #

• The {} syntax lets you define a collection of exact matches for that specific topic level.
• This one subscription will catch messages published to all three of your target topics:
  • produce/gala/seedless/color
  • produce/delicious/seedless/color
  • produce/seedless/seedless/color
• This works seamlessly with physical queues—Solace will route all matching messages to your queue just like it would with individual subscriptions, and it’s way cleaner to maintain.

A few quick notes: #

• All modern Solace brokers support topic sets, but double-check if you’re on an extremely old version (unlikely to be an issue).
• You can include as many values as you need inside the braces (even hundreds) without impacting performance, since it’s treated as a single subscription entry by the broker.
• If you ever need to mix specific values with wildcards, you can combine them too—for example produce/{gala,delicious,*}/seedless/color would match your target types plus any other apple variety.
