Logical Partition Deletion

Hi, I would like to ask question regarding logical partition deletion. I’ve recently came across this PR for PKDeletePurger, which has updated its implementation and adds new method DeleteAllItemsByPartitionKeyAsync. The name of PR says the implementation is meant for SDK 3. Can you please verify that this will be shipped with SDK 3 and if you have any estimate when? As a workaround I found that REST API of Cosmos Containers already implements ability to delete whole logical partition through calling this endpoint[Container]/operations/partitionkeydelete. I just want to verify that this approach is correct and production ready as I couldn’t find much of an info about cosmos REST API changelog, is there any? And are there any gotchas when calling cosmos db directly via REST API ?

I’ve shipped app updates that use the preview version, and it’s working as expected. As mentioned though - it seems this has been stuck in preview status for a long time now - looking forward to not have to rely on preview builds to ship production code 😉

Yes, it will be shipped on this SDK (aka v3). We expect it to be in a preview package in a couple of months by which time we will expose some metrics around the deletion, improve stability, add a sample and some documentation. There are a many caveats to using the API today and we will reduce some of them by preview - I would suggest to use alternatives in the mean time if they work for your use case: just query for and then delete items in parallel at the rate you want, or use the bulk support we have in the SDK to delete items with high throughput if you’re okay with it using all of the provisioned container throughput, etc.

@j82w, @abhijitpai, is there any expected date for this feature to be publicly available? I can see that this has been released in preview status in Feb 2022 (https://github.com/Azure/azure-cosmos-dotnet-v3/pull/2948).
