Question

Suppose ‘Acc1' is the name of your Azure Cosmos DB account. Acc1 has a database associated with it called DB1. The database again consists of a container named Cont1, which has its partition key set to /city. What should you do if you wish to modify Container1's partition key?

Answer 1

Certain features offered by Azure Cosmos DB, such as Change Feed Processor and Bulk Executor Library, can be used to perform a live data transfer between containers. This enables data redistribution to meet the intended new partition key strategy, as well as subsequent application updates. As a result, you'll be able to update your partition key.
