Learn how to optimize the network bandwidth usage in your application by taking advantage of EnableContentResponseOnWrite to avoid getting unneeded content as part of your operations with the Azure Cosmos DB .NET SDK.
When we create, update, and even delete an item in our Azure Cosmos containers, the actual body of the item is always included as part of the service response along with other useful information in the headers, like the request charge. This body content consumes bandwidth, and if we think about it, we are using almost the same bandwidth to send the operation than to receive its response. When the volume of operations it high, this accounts for quite a big chunk of data over the wire, which we might not be using at all. Wouldn’t it be great if there was a way to tell the service not to include it in the response?
Write operations include create, replace, upsert, and delete item operations. In most of them (except delete), you send a payload with the item content you want to write. And in all of them, when the operation is completed successfully on the Azure Cosmos backend, you receive a response that contains the original item content you sent, a status code indicating the success, and a set of known headers (request charge, session token, etc.). The information in the headers, which tends to be more important in these operations, often uses the smallest bandwidth.
Most of the time, we don’t really do much with the response content, because it’s what we just defined as input when we made the operation call or we plainly don’t need it (do we really need the content of the item we just deleted?). Let’s take a look at two code examples to make it more clear.
SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database.
