A connected architecture with functions refers to creating multiple functions, whereby the output of one function triggers another function and provides data for the next function to execute its logic. In this section, we will continue with the previous scenario of the storage account. In this case, the output of the function getting triggered using Azure storage blob files will write the size of the file to Azure Cosmos DB.
The configuration of Cosmos DB is shown next. By default, there are no collections created in Cosmos DB. A collection will automatically be created while creating a function that will get triggered when Cosmos DB gets any data.
Create a new database testdb within Cosmos DB and a new collection named testcollection within it. You need both the database and collection name while configuring Azure functions.
