[BUG] Closing the CosmosClient causes massive amounts of stacktrace

Describe the bug I have a singleton CosmosClient initialized in the follow manner:

 CosmosClient client = new CosmosClientBuilder()
                    .endpoint(credentials.uri)
                    .key(credentials.accountKey)
                    .consistencyLevel(ConsistencyLevel.SESSION)
                    .contentResponseOnWriteEnabled(true)
                    .buildClient();

In separate threads, I run a ChangeFeedPull similar to the examples in here: https://github.com/Azure-Samples/azure-cosmos-java-sql-api-samples/blob/main/src/main/java/com/azure/cosmos/examples/changefeedpull/SampleChangeFeedPullModel.java

When I’m done with the ChangeFeedPull logic, I try to close the CosmosClient like below.

        if (client != null) {
            client.close();
            client = null;
        }

Immediately after I call client.close(), I see a massive amount of stacktrace like below but over and over again:

To Reproduce

1. Create CosmosClient
2. Make ChangeFeelPull query from CodeSnippet below:
3. Observe stacktrace after client.close() is called.

Code Snippet

try  {
     CosmosContainer container = cosmosClientUtils.getCosmosContainer(containerId);
     CosmosChangeFeedRequestOptions options =
                CosmosChangeFeedRequestOptions.createForProcessingFromContinuation(
                        state.getChangeFeedContinuationToken().get());
        Iterator<FeedResponse<JsonNode>> responseIterator =
                container.queryChangeFeed(options, JsonNode.class).iterableByPage().iterator();
        do {
            FeedResponse<JsonNode> response = responseIterator.next();
            List<JsonNode> results = response.getResults();
            if (!results.isEmpty()) {
                // process results
            }
            state.setChangeFeedContinuationToken(response.getContinuationToken());
        } while (responseIterator.hasNext());
} catch (Exception ex) {
  / /handle exceptions
} finally {
   client.close();   // Close the CosmosClient
}              

Expected behavior CosmosClient closes successfully and we don’t see these stacktraces

This can happen when the client is closed but there are still operations running in the background on the SDK (i.e. subscribe calls). The sample you are using makes use of async client, and the shutdown part in the sample has the risk of throwing these errors. We’ll adjust the sample.

[fivetran-kevinzhao]

Okay, I finally realized why those cosmos-rntbd threads stayed open despite exiting out of the change feed loop.

Turns out the issue is not related to the change feed or closing the client, but to a query that I was making earlier on in my process.

Earlier in my code, I have a query SELECT * from c. The thing is I only really needed to get the first page of the results. I erroneously thought that the TCP connection to cosmos would terminate if I returned from that function after the first iteration or if the container object was GCed. But it now turns out that the TCP connection was kept open in the backend and it was still trying to fetch everything from that query, despite the fact that I got everything I needed and was ready to close the client. Yikes.

My simple fix was to replace the select all query with SELECT * from c offset 0 limit 100, since I just need the first page of the results anyways. This ensures that the TCP connection will have no more data to fetch after I read the first page with the 100 results. Later on, when I close the client, the client will close gracefully and not complain about the sudden closure.

Thank you @xinlian12 for taking a look initially and sorry for the trouble. Marking this as closed.
