Realm Java 0.83.0 in-memory realm multi-thread

[Kcrik K]

Hello guys,

I use Realm in my android app.

I use only Realm stored in-memory, no physical database on disk.

I would like to know if I can use such a realm in different threads ? I have tried and I get the error that the realm was created on a different thread, and when I try to create a new instance of a realm with the same RealmConfiguration, it stays stuck in native code.

So my assumption is that you can't use a in-memory Realm within different threads..am I correct or is there a way to achieve that ?

Thank you

Hell Kcrik!

Yes, you can use in-mem Realm across threads!
Like normal Realm, the same Realm instance cannot be used in different thread.
But, you can always create a Realm instance in another thread by using the same RealmConfiguration (same name, same inMemory property). They will point to the same in-mem Realm then.

Just remember, to remove the in-mem Realm from the memory, you have to close all the instances of it in every thread.
I believe you have already checked this doc :) https://realm.io/docs/java/latest/#in-memory-realm

Let us know if you have further questions!

Hi Mulong (or should I say Chen ? )

I tried what you said, but as I thought, the data is gone if I close an in-memory realm and open it again.

So how can I work around that issue. I thought the data would be lost and indeed they are, which makes sense, since nothing holds onto the data any more.

Thanks,

Chris

Ignore me guys,

my mistake was trying to use exactly the same RealmConfiguration object to instantiate another Realm in-memory, instead of creating a new RealmConfiguration from the same parameters.

Works fine now.

Thanks,

Chris
