问题 I am using a Cosmos Table API application and I need to backup all the data from all the tables every 15 minutes. How can I do this? 回答1: Since ADF only supports cosmos db sql api and mongo api,not for table api,it seems that you have to consider using Migration Tool. You could follow above example command-line: dt.exe /s:AzureTable /s.ConnectionString:"DefaultEndpointsProtocol=https;AccountName=;AccountKey=" /s.Table:metrics /s.InternalFields:All /s.Filter:"PartitionKey eq 'Partition1' and

问题 I'm working with Azure Functions for the first time. I'm trying to write a simple function which responds to documents changed or added to a CosmosDb collection. The function I've written looks like this: [FunctionName("ChangeLog")] public static void Run([CosmosDBTrigger( databaseName: "Recaptcha", collectionName: "Rules", ConnectionStringSetting = "CosmosDBConnection", LeaseCollectionName = null)]IReadOnlyList<RuleConfigCollection> documents) { if (documents != null && documents.Count > 0)

问题 How can CosmosDB Query the values of the properties within a dynamic JSON? The app allows storing a JSON as a set of custom properties for an object. They are serialized and stored in CosmosDb. For example, here are two entries: { "id": "ade9f2d6-fff6-4993-8473-a2af40f071f4", ... "Properties": { "fn": "Ernest", "ln": "Hemingway", "a_book": "The Old Man and the Sea" }, ... } and { "id": "23cb9d4c-da56-40ec-9fbe-7f5178a92a4f", ... "Properties": { "First Name": "Salvador", "Last Name": "Dali",

问题 In this SO question I had learnt that I cannot delete a Cosmos DB document using SQL. Using Python, I believe I need the DeleteDocument() method. This is how I'm getting the document ID's that are required (I believe) to then call the DeleteDocument() method. # set up the client client = document_client.DocumentClient() # use a SQL based query to get a bunch of documents query = { 'query': 'SELECT * FROM server s' } result_iterable = client.QueryDocuments('dbs/DB/colls/coll', query, options)

问题 I am new to .NET and Azure, and am trying to create a simple Web API, to help me learn. I have two collections of DocumentDB documents. The documents in each collection are defined as follows: public class Log { [JsonProperty(PropertyName = "id")] public string Id { get; set; } [JsonProperty(PropertyName = "studentName")] public string StudentName { get; set; } [JsonProperty(PropertyName = "assignment")] public string Assignment { get; set; } [JsonProperty(PropertyName = "dueDate")] public
