We are currently in the process of upgrading the MongoDb c# driver. There used to be "GrdFS" functionality to save large BSON document into chunks. Looks like the 2.0 doesn't have that feature.
We would like to know whether it is still in the scope or when can we expect this feature to be out there?
Much appreciate your response regarding the same.
You can track the feature here: https://jira.mongodb.org/browse/CSHARP-1191.
It is largely implemented, but we are waiting for the specification to be finalized. It will ship with the 2.1 version of the driver.

Is there any validation layer that validates Vulkan 1.1 compliance? Is there any convenient way to ensure that I'm not using Vulkan 1.2+ features?
Update
Here is a related github thread: https://github.com/KhronosGroup/MoltenVK/issues/1533
It seems there are potential serious downsides to using Vulkan over Metal via MoltenVK (transcribe cost).
If the application sets the apiVersion member of VkApplicationInfo to 1.1, the VK_LAYER_KHRONOS_validation layer will issue messages about any 1.2 usage.
Since you've mentioned MoltenVK, you may also want to look up information about the portability subset extension in the Vulkan specification. In particular, I think you need to enable that extension if you are going to use MoltenVK and the extension provides the ability to query for non-conformant behavior.
I have an application written on Java SE 8 that was heavily using features for mixing Heavyweight and Lightweight components.
In particular, the function "SetComponentMixingCutoutShape" was used, which was later deprecated in future versions of Java.
Now I have an option to switch to Java 11 - and I run into a problem. Seemingly, there's simply no alternative for this functionality in later versions of Java. Or at least I couldn't find one.
So what does that mean - that I simply don't have access to that feature AT ALL anymore?
Thanks for replies!
As soon as I asked I found the answer.
The functionality has been moved to component class
Before you used to call setComponentMinxngCutoutShape(component, shape);
Now you need to go component.setMixingCutoutShape(shape);
I'm wondering if anyone has ever tried to use Couchbase Lite (not Couchbase Server) in a Golang application. In other words building it into a Golang binary?
I came across this library Couchbase Lite Core and through a quick read, it looks like the underlying library for Couchbase Lite (I stand corrected)? What I couldn't find though was how to use it.
Has anyone tried to make this work with something like cgo perhaps? I'm looking to build it statically into the application so it doesn't have dependencies when distributed.
Lite Core is the underlying implementation of the upcoming 2.0 version of Couchbase Lite. It's still under development. The intention is to have a common core, with platform and language specific bindings on top.
There is currently no Go implementation I'm aware of. cgo does look like an option. Given the goal of Lite Core being the underlying implementation for all platforms, this seems on its face like a reasonable approach.
If you're interested, there's a GitHub account for community projects at https://github.com/couchbaselabs. If you work on this, it would be great to have it included there.
To see an example of platform integration, take a look at https://github.com/couchbase/couchbase-lite-ios/tree/feature/2.0
I haven't tried embedding Couchbase Lite, but my team and I make extensive use of embedded datastores like BoltDB Assuming you aren't using Couchbase's replication features heavily, BoltDB may meet your requirements.
We want to transfer data from a client to a server in realtime, so we have decided to go with WebSockets.
Using Xamarin.Forms it was surprisingly difficult to find a suitable WebSocket library.
The best match was "WebSocket4Net" because it is directly suggested on Xamarin's Homepage. However I was not able to install this library, because it only supports versions of .NET up to v4.0. (We are using v4.5)
Whenever I try to change the target framework of my PCLs from v4.5 to v4.0 I get loads of weird errors stating "Windows.Input library could not be found", "ObservableCollection could not be found" etc.
So we are currently using the library "WebSocket.Portable.Core", which although lacking some functionality worked out. However for some reason we can only receive one message. The event "MessageReceived" always is just called once.
Has anyone heard about such a problem with WebSockets? Maybe it is just time to use another library, but I just can't find one?
I also can't find any solution how to implement WebSockets natively for each platform.
WebSockets.PCL has a native implementation for each platform and it's well documented

I am trying to find a ruby based mongo driver to use in my project. It has to support replicasets and eventmachine. I'm aware of em-mongo, but it does not support replicasets. It looks like there is not a good option at the moment, but I wanted to see if anyone was aware of one before I explore mongo alternatives...
I'm a maintainer for the 10gen Ruby driver. Hang tight, we'll have support for this in the near future.
I don't believe there is anything out there (from 10gen or otherwise) that does this currently but we're actively working on a version of our driver that supports asynchronous reads and writes.
All of the official 10gen drivers are aiming to support this by mid to end of the year and the ruby driver team is already working on it. Hopefully we'll have something for you much earlier than that (likely in our 2.0 release).
You can try my fork of em-mongo with Replica Set support.
Also I am working on gem Monga which should support some modern features of MongoDB. But it is totally not production ready right now.
