Propose alternative Created Timestamp handling for OpenMetrics Text Format

[bwplotka]

Proposal

Following our protobuf change and proposal to update the text format with native histograms, it would be epic to consider designing and implementing created timestamp feature to Prometheus text format (or better to OpenMetrics Text in place of current _created series).

We consider this to be a work for a GSoC mentorship project.

Hi @bwplotka, I'm interested in participating in GSoC'24 and contributing to this project. Could you please provide guidance on any prerequisites I should fulfil beforehand?
Recently I opened a PR for UTF-8 parser for UI for the new syntax.

Hey @NeerajGartia21 are prev mentees allowed to participate in GSoC as a mentee?

[NeerajGartia21]

Yes @kartikaysaxena , afaik one can participate for the second time in GSoC but not in LFX Mentorship Program.
Also @kartikaysaxena , please don't discuss things like this in an project issue. You could have asked me personally.

Hi @bwplotka, I am interested in contributing for this project for GSoC 2024 program. Beside reviewing the historical thread of the underlying project, do you have any recommend resources that I could refer to beforehand? Furthermore, do we have a dedicated communication channel for this project?

Hi @bwplotka, I am interested in contributing to this project for GSoC 2024.
I am a software engineering student of the University of Calgary with a background in Cloud Computing, DevOps, Software Development, Open Source contribution. I also have three internship experiences in North America.

I just read the design doc and I understand what you are trying to achieve. I am wondering in order to contribute to improving and optimizing the proposed method of adding a zero-value sample with the created timestamp (synthetic zero) to the Prometheus Time Series Database? are there any other related documents I can read?
