            You can form a partition key by concatenating multiple property values into a single artificial partitionKey property.

            Azure Cosmos db is only supporting Unicode or ASCII in x-ms-documentdb-partitionkey while github.com/vippsas/go-cosmosdb package is using json.Marshal which internally transforms Unicode to Chinese characters automatically.

            The only way to solve it is using English as partition key when creating documents.

            Validate ADF debug for Copy data "Move and Transform Functionality"
            Asked 2021-Jun-13 at 13:45

            I am using ADF as a pipeline for writing data from Cosmos to Kusto database by writing following activity:

            1. Create temp table in Kusto database.
            2. Copy data from cosmos to temp table.
            3. Delete the original table, if exist in Kusto database.
            4. Rename temp table to original table.

            All these changes are part of JSON file from my GIT repo.

            I read online that debug process in ADF does not published the changes, so I am not able to see changes in my Kusto database(temp table creation, data copy, old table deletion, renaming of temp table).

            How and where to see all the changes done during Debug process of pipeline in ADF and validate(Verify that the correct table name is created and the data is dump properly in the temp table)?

            ANSWER

            Answered 2021-Jun-13 at 13:45

            Debug process runs the pipeline in the same manner as a published one and you should see the table creation, the data ingestion and the rename operation just as if you published and run it by setting a trigger or trigger manually.

            However running a pipeline in a debug mode won't publish the changes to the pipeline so future triggers won't include the changes made in the debug session. To include those changes you need to publish the pipeline.

            Asp.net core 3 application slow to load cosmos db query

            Answered 2021-Jun-12 at 10:27

            First, I would highly recommend that you (or anyone using Cosmos DB .Net SDK) to watch this video on Cosmos DB Youtube Channel: https://www.youtube.com/watch?v=McZIQhZpvew. This provides really useful information about the best practices to follow when working with this SDK.

            This video will explain why the first request takes so much time and how you can speed that up.

            To summarize for the purpose of this answer, creating an instance of Cosmos Client (with "Direct" connection mode) does not do much. When you make the 1st request with that client, the initialization happens and at that time SDK makes a few network requests to get necessary information about establishing "Direct" (TCP) connection. That's why it takes a great deal of time with the 1st request. After the 1st request, the information is cached by the SDK so subsequent requests take much less time than the 1st one.

            To do the initialization while creating Cosmos client, you would need to use CreateAndInitializeAsync method of the CosmosClient. Here's an example of the same from the documentation page:

            Is there any Azure Data factory activity to get cosmos collection list?
            Asked 2021-Jun-09 at 09:24

            Is there any option in Azure Data Factory to know the list of collections available in a particular database in Azure cosmos account?

            Want to execute the particular activity - which returns list of collections in a cosmos db, every time when the Azure Data Factory pipeline get executed.

            Exact requirement: Want to do copy data from all the collections from cosmos db but the list of collections in the cosmos db may vary as the time progress. If any new collection has been added to the cosmos db, dynamically that new collection needs to be considered as part of the copy activity without any external intervention.

            I am not sure if a direct way exists but for a workaround you can

            1. Make a HTTP call to this API Get List of Collections. Making a REST API call will ensure you always have latest data.
            1. Parse the JSON response to get the collections. Followed by a For-Each Activity perhaps.

            Edit- Adding discussion in comments to the answer

            1. Make a Http Trigger function that can be called by a Web Activity.
            2. Obtain AAD token inside that function
            3. Call the REST Api to get list of cosmos collections
            4. Return json-array as response
            5. Add a For-each activity in ADF to loop over the list of collections.

            Azure Cosmos DB - intermittent MongoConnectionException / IOException / SocketException
            Asked 2021-Jun-07 at 18:31

            I'm using Azure Cosmos DB 4.0 with MongoDB C# Driver 2.10.4.

            Most of the times the queries work fine, but I'm getting intermittent errors like this:

            MongoDB.Driver.MongoConnectionException: An exception occurred while sending a message to the server. System.IO.IOException: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host. System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.BeginSend(... at System.Net.Sockets.NetworkStream.BeginWrite --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.BeginWrite at System.Net.Security._SslStream.StartWriting at System.Net.Security._SslStream.ProcessWrite at System.Net.Security._SslStream.BeginWrite

            When that error happens the call takes 10-25 seconds before failing.

            I'm building the MongoClient with new MongoClient(MongoClientSettings.FromConnectionString(cnstr)) and I was using the connectionstring with these arguments ?ssl=true&replicaSet=globaldb&retrywrites=false.

            I tried with retryWrites=true (as per Azure Support suggestion) but that didn't help.

            I tried different settings and that didn't work either (connect=direct, maxIdleTimeMS=30000, serverSelectionTimeout=5000ms, socketTimeout=10000ms).

            What's causing those exceptions?
