When using the Azure Cosmos DB .NET SDK v3 for NoSQL you get a “413 Entity too large” error while uploading a set of files. Based on that error, which of the provided file sets can be uploaded to the Azure Cosmos DB for NoSQL container?

The "413 Entity too large" error indicates that the combined size of the files being uploaded exceeds the maximum item size limit for Azure Cosmos DB, which is 2 MB. To resolve this, you must ensure that the total size of the files in a single operation does not exceed this limit. Let's assume the file sizes are: File1: 0.5 MB File2: 0.5 MB File3: 0.7 MB File4: 0.8 MB File5: 0.9 MB If you try to upload File1, File2, and File3, the total size would be 0.5 + 0.5 + 0.7 = 1.7 MB, which is within the 2 MB limit. However, if you add File4 (1.7 + 0.8 = 2.5 MB) or File5 (1.7 + 0.9 = 2.6 MB), the total exceeds 2 MB, leading to the "413 Entity too large" error. Therefore, only File1 and File2 (total 1 MB) can be uploaded without encountering the error, assuming the error was triggered by adding more files beyond that point.
