You really shouldn't be changing the target for the SendData object. This was just discussed with @shreyamalpani for #1134 and #1139

Could you elaborate why? I don't see enough discussion in those two PRs.

The send_with_retry module uses the endpoint. It's creates inconsistent behavior if the endpoint changes between retries.
The coalesce_send_data function sorts and deduplicates SendData based on endpoint properties. Changing the endpoints can lead to invalid deduplication and/or merged payloads being sent to the wrong destination.
send_data also has async code that uses the endpoint. Changing them can cause unexpected behavior and race conditions.

Thanks for the context! Will it still be a concern if we only expose set_api_key()? From a quick look at your code pointers, I see url, timeout_ms and test_token used, but not api_key.

Changing the API key wouldn't impact the coalesce_send_data function, but it would impact send_with_retry which calls to_request_builder() which uses the api key. Changing just the API key can cause another issue; I don't think it's a particularly good design, but send_data determines whether to serialize to msgpack or proto based on the presence of an API key. If that switches from None to Some while the url remains the same it can lead to runtime errors.
If you need to lazily add the api key, I'd suggest adding a with_api_key() function to SendDataBuilder.

Sure! I limited all the changes to SendDataBuilder. Could you take a look?

Add functions to
SendDataBuilder:with_api_key()with_retry_strategy()len()is_empty()Motivation
DataDog/datadog-lambda-extension#732 We want to lazily set api key in the
target, i.e. leave it empty at creation time then set it later.As a result, we need to pass
SendDataBuilderaround in the codebase, instead of passingSendData. Wherever we need to set/get data onSendDataright now, we need to do them onSendDataBuilderinstead.How to test the change?
