Help us understand the additional delay in DEADLINE_EXCEEDED error

[antonmithun-work]

I am setting the deadline for my gRPC call as 5ms using the following code:

stub.withDeadlineAfter(5L, TimeUnit.MILLISECONDS) .doSomething();

However, I am receiving a DEADLINE_EXCEEDED error message with the following details:

DEADLINE_EXCEEDED: ClientCall started after CallOptions deadline was exceeded. Deadline has been exceeded for 0.012145204s.

The error message indicates that the deadline was exceeded by approximately 12ms, which is longer than the specified 5ms.

What could be causing this additional delay ?

A call goes to pending state until name resolution is done. Name resolution callback results in the pending call getting picked up and reprocessed to start the real call. The time elapsed so far is noted and checked whether the call deadline has already exceeded, and if so the call is failed.

I hope your issue is resolved. Feel free to comment to reopen in the future if needed.
