APIM premium tier - how many cache slots available ? (unique cache keys available)

Question

I want to store several thousands of unique cache key -values in the inbuilt cache .
APIM Prem tier. Is there a limit?
I came across a limit which says 100 caches available in Standard V2. But couldnt find anything on premium tier. I am sure there would be a limit, but what is that limit?

Answer 1

@Martin Kallukalam Thanks for reaching out. I had a discussion internally and confirmed that in v1 tiers (stv1 and stv2) there is no limit on cache slots. For your reference all dedicated sku limits are here https://github.com/MicrosoftDocs/azure-docs/blob/main/includes/api-management-service-limits.md if doesn't mention then it means no limit.

do let me know incase of further queries, I would be happy to assist you.

Answer 2

Thanks for posting your question in the Microsoft Q&A forum.

In the Azure API Management Premium tier, the built-in cache size is 5 GB per unit. There is no explicit mention of a limit on the number of unique cache key-value pairs that can be stored, but the cache size is the primary constraint. If you need more cache capacity, you can extend the default cache size by using an external Azure Cache for Redis. This approach allows you to manage larger datasets beyond the built-in cache limitations.
