问题 We are kind of POC phase where we are trying out Azure. We are using Grails, which has nice support for MongoDb as backend (using GORM), but couldn't find similar support for DocumentDd. If we choose to go with DocumentDb, our choice would be to have a layer (may be kind of DAO layer) which uses documentDb client library and interacts with DocumentDb. Or we fall back to MongoDb, as its provided Azure. Any other choices we have with Grails-DocumentDb? 回答1: You should be able to use DocumentDB

问题 As this doc said, "You currently cannot use GROUP BY with an ORDER BY clause but this is planned". But we do need to group by one field and order by another field. Is there a way to do it? 回答1: According to my research, i'm afraid that there is no such direct official way to use GROUP BY with ORDER BY since the statement you mentioned in your question: The GROUP BY clause must be after the SELECT, FROM, and WHERE clause and before the OFFSET LIMIT clause. You currently cannot use GROUP BY

问题 I'm generating some JSON files in .NET Core app. I want to import a json file to Azure Cosmos DB as soon as it is created. Is there some way to achieve it from a .NET Core code. Thanks in advance! 回答1: According to my test, if you want to use Cosmos DB Bulk insert in .Net core application, you need to use the .Net CosmosDB SDK V3 and its version must be larger than 3.4.0.
