Bulk & Batch Support

[mumby0168]

I have just been watching this video

https://channel9.msdn.com/Shows/Azure-Friday/How-to-do-Bulk-and-Transactional-Batch-operations-with-the-Azure-Cosmos-DB-NET-SDK

Really got me thinking, we already seem as tho we support bulk, I think if we turn the feature on in theComosClient and then group up all our tasks then this will work, would need to verify this.

Batch however is really cool and would be interesting to look at, what do people think?

Hi @mumby0168 - yes, there has been an option for this since this thing was created:

azure-cosmos-dotnet-repository/Microsoft.Azure.CosmosRepository/src/Options/RepositoryOptions.cs

Line 66 in 64271f6

public bool AllowBulkExecution { get; set; }

And, it is assigned here:

azure-cosmos-dotnet-repository/Microsoft.Azure.CosmosRepository/src/Providers/DefaultCosmosClientOptionsProvider.cs

Line 52 in 64271f6

AllowBulkExecution = ro.AllowBulkExecution

Ahh, I see didn't realize! Does the SDK still provide the same support with it been a ValueTask<T> return type I had seen you have to use Task.WhenAll(valueTasks.Select(vt => vt.AsTask()) to tell the cosmos SDK to execute this as a bulk operation. Just wondered if that had any impact on the way they have implemented it? Can't imagine it does.

It shouldn't matter, with my testing of it earlier on - it appeared to work correctly. They internally track invocations, in fact their code is all open source - you can look at how they're doing it.
