See original GitHub issue

We are continuously addressing and improving the SDK, if possible, make sure the problem persist in the latest SDK version.

Describe the bug On Azure AppService I’ve hit a System.OutOfMemoryException while using CosmosDB, I restarted the service and it hasnt occurred since this morning, I was unable to reproduce it on my Local environment

When looking at the app insight it doesn’t seem memory was full on system at the time of error ~250mb from 4gb

To Reproduce Still unsure how

Expected behavior No errors

Actual behavior Errors

Environment summary SDK Version: 3.19.0 OS Version (e.g. Windows, Linux, MacOSX) Windows 10

Additional context Add any other context about the problem here (for example, complete stack traces or logs).

Why are you special casing maxItemCount == 1? You should just draining the query regardless of the maxItemCount:

public async Task<List<T>> ExecuteQueryAsync<T>(PartitionKey partitionKey, Container container, QueryDefinition query, int maxItemCount = -1, int maxConcurrency = -1)
        {
            var tmpResult = new List<T>();

            using (FeedIterator<T> resultSetIterator = container.GetItemQueryIterator<T>(
                    query,
                    requestOptions: new QueryRequestOptions()
                    {
                        PartitionKey = partitionKey,
                        MaxItemCount = maxItemCount,
                        MaxConcurrency = maxConcurrency,
                    }))
            {
                 while (resultSetIterator.HasMoreResults)
                    {
                        FeedResponse<T> response = await resultSetIterator.ReadNextAsync();
                        if (response != null)
                        {
                            tmpResult.AddRange(response);
                        }
                    }

                return tmpResult;
            }
        }

I would think that aggregations are expected to consume RU and Memory since some of those operations need the data to be first drained. @timsander1 do we have any advice for these type of complex query?

@zejtin Was there any progress on the memory investigation?
