Provider Free Platform Cache - Cache Invalidation Question

@Gaurang Mathur @Matthew Parin In the Platform Cache Considerations document, it is stated that "Some or all cache is invalidated when you modify an Apex class in your org".

 

I'm wondering if this is done cross-namespace, or only within a namespace? Specifically, I'm curious if ISV Platform Cache is protected from invalidation by an Apex Class modification in subscriber org's custom namespace

    The session cache can store values up to eight hours. The org cache can store values up to 48 hours.

2GP Provider Free Platform Cache

I'm trying to build a beta 2GP package with provider free platform cache (the package has passed security review).   However I get this: 

 

[Error]: Package creation failed with error:                

                    package: Invalid provider free capacity allocation. Provider Free capacity not available

 

Any idea why that might be?  Everything works in scratch orgs with the "PlatformCache" scratch org setting enabled.

 

The cache is defined as:

 

<?xml version="1.0" encoding="UTF-8"?>
<PlatformCachePartition xmlns="http://soap.sforce.com/2006/04/metadata">
    <description>...</description>
    <isDefaultPartition>false</isDefaultPartition>
    <masterLabel>package</masterLabel>
    <platformCachePartitionTypes>
        <allocatedCapacity>0</allocatedCapacity>
        <allocatedPartnerCapacity>0</allocatedPartnerCapacity>
        <allocatedPurchasedCapacity>0</allocatedPurchasedCapacity>
        <allocatedTrialCapacity>0</allocatedTrialCapacity>
        <cacheType>Session</cacheType>
    </platformCachePartitionTypes>
    <platformCachePartitionTypes>
        <allocatedCapacity>3</allocatedCapacity>
        <allocatedPartnerCapacity>3</allocatedPartnerCapacity>
        <allocatedPurchasedCapacity>0</allocatedPurchasedCapacity>
        <allocatedTrialCapacity>0</allocatedTrialCapacity>
        <cacheType>Organization</cacheType>
    </platformCachePartitionTypes>
</PlatformCachePartition>

    @Matthew Parin Any idea why an ISV might get this error when uploading a second generation package with Provider Free Platform Cache?  Thanks!

Are there some restrictions around platform cache and the automated process ?

I've a platform event that needs to run a process that includes reading something from the Org wide cache. The process is run as the Automated process (via the PE trigger) and it cannot read the Org cache value so doesn't work. Appreciate any thoughts. Thanks

The linked SFSE question covers the problem in more detail, but generally, if I'm in Apex and have a Cache.OrgPartition, how can I tell if it actually has any capacity to cache data without calling getCapactiy()?

 

I don't want to waste resources trying to cache things into an empty cache. Nor to I want to call the potentially expensive getCapacity() method when I'm trying to use the cache to avoid expensive operations.

How can I detect that a packaged Platform Cache Partition has no capacity allocated?

Great news to share! Our own @Anil Jacob just published a Salesforce Developer Blog post on Platform Cache.

 

If you ever wanted to learn more about Platform Cache, start here: https://developer.salesforce.com/blogs/2020/06/caching-in-the-salesforce-platform.html.

 

And once you're ready for even more Platform Cache, head over to @Karishma Lalwani's page. She has a survey out to the Salesforce Trailblazer Community that will definitely be of interest. Link: https://success.salesforce.com/0D53A00004v6s5l.

    @Anil Jacob

    I appreciate your feedback.

    To clarify the use case here, what we're effectively doing is collecting session level metrics on Apex transactions that were kicked off by CRUD API calls. The destination of the data collected is a logging framework rather than the record that fired the trigger. The use of Session Cache is to ensure we don't waste cycles logging metrics we've already seen in the same session. If the same or different user fires the same trigger we do want different outcomes because those are new metrics to record.

    As long as I know I can depend on current behaviour I'm good. Thanks again!
