Objectbox Sync Early Access

[ramsundark5]

Thanks for the wonderful library. When is objectbox sync going to be released? I signed up for early access a while back and have received no updates so far.

[greenrobot-team]

We're on it. Progress is looking good. So I guess a preview will be available soon? -Uwe

[devjn]

Is there any update? At least some estimate?

[greenrobot-team]

As usual, it's done when it's done. We don't/can't share any timelines.

[jrcacd]

We are looking forward for this

[axebelk]

We are still waiting to explore this feature, Or guide us the way to build a custom solution for this feature. The most awaited feature is not released even after many years. I can't switch to another DB in middle of project. So this is just disappointed.

We appreciate the work you have done and are continuing to do. Some of us chose Objectbox particular for the Sync feature and would really appreciate a rough estimate on this (next month, next year, in 5 years, never, etc) so we can plan for the future. A lot of us would gladly pay for this service, it would be much cheaper than building out and migrating to alternative solutions. A rough estimate or timeline would be much appreciated. Keep up the great work.

A quick update on Sync status: We are currently working with select projects/use cases on early Sync implementation. If you're interested in learning more, please get in touch with us via the contact form on https://objectbox.io/sync/.

I just started to implementing my own sync adapters. Your package ruined my time and business. Good bye

[flatlanderer]

@axebelk is your sync implementation is also open-source?

[flatlanderer]

An open question to Objectbox developers, from the website, says "ObjectBox has been running on 30k+ apps, and millions of devices" my question is, if Sync is still in beta, how did these 30k apps and millions of devices was able to sync their data to the server? Does it mean, all these usages are only used for local storage or temporary storage solution?

[axebelk]

@axebelk is your sync implementation is also open-source?

Not an open source project, I developed for my own project with mongodb + django as a backend.

[cyberquarks]

@greenrobot-team can ObjectBox work on a server environment? And can it work on a clustered environment for high-availability?

[linisme]

@greenrobot-team Thanks for your great job, I want to know is Objectbox Sync also open-source and Free?

[greenrobot-team]

AFAIK same as for "regular" ObjectBox the Java part is open source, the JNI/native parts are not. E.g. you can already see the sync related code as part of this repository: https://github.com/objectbox/objectbox-java/tree/main/objectbox-java/src/main/java/io/objectbox/sync

[cyberquarks]

@linisme looking at the code linked by @greenrobot-team it shows that the "sync" codes there are for your client app, the server implementation is still unknown.

Here's a code from the docs:

SyncClient syncClient 
    = Sync.client( 
            boxStore,  
            "wss://127.0.0.1" /* Use ws for unencrypted traffic. */,  
            SyncCredentials.apiKey("api-key")).build(); // Connect and start syncing.

So this WebSocket server is the real server to which ObjectBox will sync into.

https://github.com/objectbox/objectbox-java/blob/4cb0ca5df78161fdf8e02c0ea1770dda89896e26/objectbox-java/src/main/java/io/objectbox/sync/server/SyncServerImpl.java

There's also a native interface that I think does the actual "sync" to the server.

@greenrobot-team can you confirm that ObjectBox Sync is not planned to be available for free in a scenario when the server part is hosted on clients' premises (not part of your paid cloud services)? My understanding is that Greenrobot will not publish the Sync server code for free download, am I right?

[greenrobot-team]

@ddekanski I guess you should email about this ([email protected]) to learn more. This issue is more about discussing the technical stuff.

[savilmehra]

Hi, How sync happen between two servers (e.g sync between server is in premises and cloud server ) any documentation available?

[greenrobot-team]

@savilmehra There is no documentation currently that I am aware of. I suggest to email your ObjectBox contact about this.
