Inconsistent Sampling Result Names#938
Conversation
- `NOT_RECORD` - `RECORD` - `RECORD_AND_SAMPLED` Seems like we should pick between present tense or past tense and make it consistent. I am proposing that we use past tense as in it's a decision that has already been made. `NOT_RECORDED`, `RECORDED`, `RECORDED_AND_SAMPLED`. `NOT_RECORD` doesn't make sense. It is not correct English.

Thank you! This was already irking me for quite some time. 😄

I think current description of Samplers in Trace SDK is not very clear. I am looking at Java SDK and there sampling response is kinda imperative: it tells SDK to create a Span with specific behaviour (isRecording, isSampled). So it is not past tense like in "some action has been done". It is more "the decision has been made, now act this way". Therefor I totally agree that names could use some unification, but I think new names should be in imperative mood, not just past tense verbs. |
It is, thanks :)
I disagree, but both ways are Ok. |
|
Hmm, what would be the imperative names? |
|
I kind of like them being imperative as well. I think the imperative version would be:

What about |
|
I'm good with that. They are consistent and I think they make sense. |
|
I now remember there was once confusion about whether IsRecording determines the sampling result or the other way round, see #871 (comment). I think using imperative mood here would actually make this confusion less likely, so I changed my opinion and agree with @iNikem that imperative mood is probably better for this enum. |

@ejsmith if no existing issue filed, can you file one so we can track? |

| * A sampling `Decision`. One of the following enum values: | ||
| * `NOT_RECORD` - `IsRecording() == false`, span will not be recorded and all events and attributes | ||
| * `IGNORE` - `IsRecording() == false`, span will not be recorded and all events and attributes |

Since the description says "will be dropped" here, maybe DROP would be an even better name. I'm fine with IGNORE or SKIP too though.

I think I like DROP better.

+1 for DROP. This is necessary for opentelemetry-cpp because IGNORE is defined as macro as constant. This build failure for details.

@ThomsonTan Then the main problem there seems to be that you have defined a macro constant 😃 And isn't the usual C++ idiom to only have macros/defines in ALL_CAPS? Then you would write SamplingResult::Drop or SamplingResult::drop or similar.

@Oberon00 the problem is not defined by opentelemetry-cpp, as IGNORE is sounds like a common word, there is chance of name collision. Change casing in C++ sounds a good suggestion though.
