Is DocumentClient thread safe?
I get mixed messages:
From MSDN https://msdn.microsoft.com/library/azure/microsoft.azure.documents.client.documentclient.aspx :
Any public static ( Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
From MS blog https://azure.microsoft.com/en-us/blog/performance-tips-for-azure-documentdb-part-1-2/ :
SDK Usage Tip #1: Use a singleton DocumentDB client for the lifetime of your application Note that each DocumentClient instance is thread-safe and performs efficient connection management and address caching when operating in Direct Mode. To allow efficient connection management and better performance by DocumentClient, it is recommended to use a single instance of DocumentClient per AppDomain for the lifetime of the application.
