Research direction

Start with the DTFxClient.CreateOrchestrationInstanceAsync call shown in the report and trace why awaiting its task can take 3–5 minutes; the title also names DTFxClient.GetOrchestrationStateAsync. Reproduce the reported latency if possible, identify the responsible path, and verify that orchestration instances can be queued without the reported delay.

Written by the indexing model from the issue text.

Description

Hey, we are using DTFX for async job, but we are getting significant latency while creating orchestration instances.

"Task task = DTFxClient.CreateOrchestrationInstanceAsync(
NameVersionHelper.GetDefaultName(orchestrationType),
NameVersionHelper.GetDefaultVersion(orchestrationType),
instanceId,
input,
tags,
dedupeStatuses);

var result = await task;"

We are awaiting on the task so that it can give guaranty to the caller that instances have been queued. But that await is causing latency to shoot up as in worst case we are getting max delay of 3 to 5 mint for this task to finish.
