unable to set "setPersistenceCacheSizeBytes"

[luciofncnd]

Hi, I'm unable to use the "setPersistenceCacheSizeBytes" for local storage.
As stated in the docs it should apply to Database default instance:
https://firebase.google.com/docs/reference/android/com/google/firebase/database/FirebaseDatabase#public-synchronized-void-setpersistencecachesizebytes-long-cachesizeinbytes

I'm trying with :
FirebaseDatabase.DefaultInstance.setPersistenceCacheSizeBytes(10000000);

But Unity tells me:
'FirebaseDatabase' does not contain a definition for 'setPersistenceCacheSizeBytes' and no accessible extension method 'setPersistenceCacheSizeBytes' accepting a first argument of type 'FirebaseDatabase' could be found (are you missing a using directive or an assembly reference?)

Is there another way to set it ?

Can you help me out ?

Thanks in advance.

Hi luciofncnd, it looks like you're right, there was an oversight and that function didn't get hooked up despite there being documentation for it. We'll try to get it fixed as soon as we can. We'll update this bug when it's fixed.

ok, I understand. Is there another way to set the Cache Size ? What's the actual size if not changed ?
Thanks in advance.

Sorry for the late reply. The default cache size is 10MB.
