Proposal: Custom application counters

[Oleg Pylnev]

Hello All,

 

It would make sense to allow OpenSocial applications to have own set of global counters.

 

Using Global App Data store does not work due to concurrency, so here is the proposed set of methods:

 

newIncrementGlobalAppCounter(id, value) // value can be negative/positive

newUpdateGlobalAppCounter(id, value) // creates counter or forces specific value for counter.

newFetchGlobalAppCounters(ids)

newRemoveGlobalAppCounters(ids) // Removes counter (optional)

 

Regards,

Oleg Pylnev

Oleg,

Can you provide some use cases? For applications which have their own backends this if functionality I can see them implementing on their own.

Cheers

The apps with own backend will not need it.

 

But for developers who wants to host most/all of app data on container, it makes sense. I do not believe that Amazon S3 provides custom counters either due to ‘eventual consistency’ of data updates.

 

As for use cases, I can see ‘bitten by zombies this week’ counter or ‘total songs played today’ counter.

Again, how do you prevent mischievous gadget users from tampering with the app counters?

-1 because of the huge potential for abuse.

-1 Yeah, this is the reason we never allowed updating of the global app data way back in 0.5.. you just can't trust javascript (or your friend's javascript)
Perhaps we can help developers in another way? (I don't have any ideas right now, but maybe someone else does...)

This issue is not receiving much positive attention or consensus for 0.8 so I'm considering it closed for now.
Thanks.
