问题 I have a cosmosGB gremlin API set up with 400 RU/s. If I have to run a query that needs 800 RUs, does it mean that this query takes 2 sec to execute? If i increase the throughput to 1600 RU/s, does this query execute in half a second? I am not seeing any significant changes in query performance by playing around with the RUs. 回答1: As I explained in a different, but somewhat related answer here, Request Units are allocated on a per-second basis. In the event a given query will cost more than

问题 I am trying to get and reset the master keys for an Azure Cosmos DB account from code, specifically from C# code in an Azure Function App whose system assigned managed identity has an RBAC role defined on the Cosmos DB account.

问题 I'm trying to execute a query but facing this error. Below query is the simplest form of what I was trying to achieve. g.V('Users12345').as('u'). project('id', 'email', 'test'). by('id'). by('emailId'). by(where(values('id').is(eq(select('u').values('id'))))) I was trying to use select inside project. What's that I'm missing here? 回答1: The invalid part is eq(select('u').values('id')) . I guess "the query in its simplest form" means that you're aware of it being pointless. Assuming that u is

问题 UpsertItemAsync has an optional parameter where you can indicate the PartitionKey . This is for the 'new' CosmosClient and not for the 'old' DocumentClient. https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.cosmos.container.upsertitemasync?view=azure-dotnet As the documentation says - it is optional because if you do not supply one, it will be automatically extracted from the item. Isn't that perfect? Is there any conceivable situation under any circumstances where that is not what

问题 The documentation on the Azure site for CosmoDB & Gremlin & Python[1][2][3] use bad practices - tons of code duplication and concatenating strings to form queries, rather than using native python. However, when trying to use the native SDK, there's a 2 year old bug that prevents it due to serialization errors[4]. What's the best way to use Gremlin & Python with CosmosDB? Should I give up on Gremlin altogether - and if so, what's the alternative solution? [1] https://docs.microsoft.com/en-us

问题 I have an azure function triggered by Cosmos DB. I am getting the data from the JSON file and send it over to my SQL database on Azure.

I have connected to it once through the portal, but I can't see that I am connected to my database under View/Cloud Explorer in Visual Studio. The database is only listed under View/SQL Server Object Explorer . I assume this connection is through my local machine, and not
