Azure Functions: Getting 'Execution Timeout' when retrieving large datasets from Cosmos DB
I'm trying to configure I'm currently working on an Azure Function that retrieves large datasets from Cosmos DB and processes them. However, I'm running into an scenario where the function times out, throwing the behavior `Function execution timed out`. My function is set to a timeout of 5 minutes, and the dataset I'm trying to retrieve can be up to 10 MB in size. Here’s a simplified version of my code: ```csharp using System; using System.Linq; using System.Threading.Tasks; using Microsoft.Azure.Documents.Client; using Microsoft.Azure.WebJobs; using Microsoft.Extensions.Logging; public static class MyFunction { [FunctionName("RetrieveData")] public static async Task Run([TimerTrigger("0 */5 * * * *")] TimerInfo myTimer, ILogger log) { var client = new DocumentClient(new Uri("<your-cosmosdb-uri>"), "<your-cosmosdb-key>"); var collectionUri = UriFactory.CreateDocumentCollectionUri("<your-database>", "<your-collection>"); var query = client.CreateDocumentQuery<MyData>(collectionUri, new FeedOptions { MaxItemCount = -1 }).AsDocumentQuery(); var results = new List<MyData>(); while (query.HasMoreResults) { var response = await query.ExecuteNextAsync<MyData>(); results.AddRange(response); } // Process results here } } ``` I've tried increasing the timeout setting in the Azure portal, but it still times out. I also considered using pagination by setting a limit on the number of items retrieved with `MaxItemCount`, but I’m unsure how to implement this appropriately. Additionally, I noticed that my function has a consumption plan; could switching to a premium plan help with this scenario? Any advice on how to handle large datasets efficiently in Azure Functions would be greatly appreciated! I've been using Csharp for about a year now. I'd really appreciate any guidance on this.
