Timeout for LINQ queries

Describe the bug Request timeout set on CosmosClientBuilder using WithRequestTimeout is not respected by Container.GetItemLinqQueryable. When I run a heavy query, it does not return nor throw after the request timeout of 1 second passes.

I am aware that this request timeout is interpreted as a network request timeout, not an operation timeout. However, in this case, the client does not receive anything from the server. I put a breakpoint to the loop in CosmosLinqQuery.GetEnumerator() and I can see no results are returned before the timeout passes.

EDIT: What’s also troubling is that it keeps hanging indefinitely on localFeedIterator.ReadNextAsync. I left it running for a couple of minutes and it didn’t do anything. There surely must be some timeout enforced downstream, right?

To Reproduce Execute a heavy LINQ query and set a request timeout of 1 second.

Expected behavior The request timeout is respected.

Actual behavior The query keeps running even after the timeout period passes.
