Azure DocumentDB, or shortly DocumentDB, is a NoSQL document database service offered by Microsoft.
This library offers a set of classes to work with DocumentDB using .NET C# 6.0.
The framework also has a DocumentDB history backup solution. The backups will be created in a different collection (in the same database or in a different one).
The implementation is very simple and will only backup the documents. A complete Microsoft backup solution is already planned.
####Service definition:
public class FoodService : DocumentDBService
{
public FoodService()
: base(endPointUrl, authorizationKey, database)
{
// Create collection service
ShoppingList = CreateCollectionService<Item>("ShoppingListCollection").Result;
// Create a backup service for the shopping list collection
BackupService = CreateCollectionBackupService(ShoppingList);
}
public ICollectionService<Item> ShoppingList { get; }
public IBackupService BackupService { get; }
}####Create and restore backups:
using (var foodService = new FoodService())
{
Console.WriteLine("\n> Create some documents:");
foodService.ShoppingList.CreateDocument(new Item { Name = "Milk", Description = "Skimmed milk" }).Wait();
foodService.ShoppingList.CreateDocument(new Item { Name = "Milk", Description = "Whole milk" }).Wait();
foodService.ShoppingList.CreateDocument(new Item { Name = "Water", Description = "Mineral" }).Wait();
foreach (var item in foodService.ShoppingList.AllDocuments)
{
Console.WriteLine($"- {item.Name}- {item.Description}- {item.Id}");
}
Console.WriteLine("\n> Find all items with name = Milk:");
foreach (var item in foodService.ShoppingList.Where(d => d.Name.Equals("Milk")))
{
Console.WriteLine($"- {item.Name}- {item.Description}- {item.Id}");
}
Console.WriteLine("\n> Create a backup:");
var backup = foodService.BackupService.CreateBackup("my backup").Result;
Console.WriteLine("Backup created at" + backup.Timestamp);
Console.WriteLine("\n> Delete water:");
foreach (var item in foodService.ShoppingList.Where(d => d.Name.Equals("Water")))
{
Console.WriteLine($"Delete: {item.Name} - {item.Id}");
foodService.ShoppingList.DeleteDocument(item.SelfLink).Wait();
}
Console.WriteLine("\n> Restore backup:");
foodService.BackupService.RestoreBackup(backup);
Console.WriteLine("Backup restored!");
Console.WriteLine("\n> List all the documents:");
foreach (var item in foodService.ShoppingList.AllDocuments)
{
Console.WriteLine($"- {item.Name}- {item.Description}- {item.Id}");
}
Console.WriteLine("\n> Delete database:");
foodService.ShoppingList.DatabaseService.DeleteDatabase().Wait();
}
