Azure Cosmos DB: Partial document update now in general availability

Published date: November 02, 2021

Prior to the partial document update feature, all data updates in Azure Cosmos DB were done as complete document replacements. Now with partial document updates, you can specify what data has been changed in the update request and then Azure Cosmos DB updates the data that has been changed service-side. Use this feature to reduce network payload sizes by not having to send the full document, as well as avoid an extra read operation if an update fails concurrency checks. This feature works with any connectivity mode and on existing Azure Cosmos DB accounts and containers with support today in the Azure Cosmos DB .NET and Java SDKs.
