Scheduled stepdown for smoother MongoDB primary election
Tags: mongodb
Published: 2024-06-15 12:02:59

Stepdown is a great tool that allows us to keep clusters operating smoothly. We use it for example when we want to perform some maintenance work on the host where the primary is currently running, to perform a rolling upgrade, and in many other cases we need to switch the primary to another node. 

While usually electing a new primary is fast enough, for clusters with very high write traffic, it sometimes unfortunately leads to write errors on the application side. The reason is that drivers need to disconnect from the previous primary and connect to the new one, and this takes time. All write attempts at this time end with an error. Of course those operations can be retried after a short time, but it seems to me that this situation could be avoided fairly easily. 

Here's my idea:

- We add an optional parameter to the stepDown method, let’s name it: `electionEffectiveTimeSeconds`. If we do not set it, stepDown works normally - as before,

- The new primary is elected, but the cluster and drivers do not use it as a primary yet, instead they wait for electionEffectiveTimeSeconds seconds after the election is done,

- Until then, the previous primary handles write operations,

- In the meantime, all cluster nodes and drivers receive information about the new primary and when the change will take effect - based on electionEffectiveTimeSeconds,

- This will allow all parties to properly prepare for the switchover, which should minimize the time of unavailability of the primary,
When the time expires, clusters and drivers change primaries to the new node.

The key element will be to determine the optimal range for this new parameter. On the one hand, it must be big enough to give enough of time to spread the information through the cluster and drivers. On the other hand, it must not be too long, because there is a risk that - during that time - the new elected primary will catch a lag and will not be able to become a primary. In this case, however, it could try one more time, and if that too fails, then perform a normal stepdown a third time.

I think this method would be useful during all stepdowns, which are planned in advance and it is not necessary to happen immediately.


I am curious about your opinions, if you see value in this, I will be grateful for the upvote [here](https://feedback.mongodb.com/forums/924280-database/suggestions/48541538-scheduled-stepdown-for-smoother-primary-election).

Ethical and Social Implications: The development of AI raises ethical and societal questions that impact scientific research and its applications. Issues such as bias in AI algorithms, data privacy, and the ethical use of AI in research settings require careful consideration.

[Future Directions](https://www.amodra.in/): The integration of AI into scientific fields opens new avenues for exploration and discovery, enhancing our understanding of natural phenomena and potentially leading to breakthroughs in areas such as medicine, climate science, and space exploration.

In essence, while science provides the [foundation of knowledge]( https://in.pinterest.com/amodra_in/) and understanding of the natural world, artificial intelligence augments scientific capabilities, offering powerful tools and methodologies to advance research, solve complex problems, and address societal challenges. The synergy between [science](https://www.instagram.com/amodra.in/

Evolution of the concept of open source
Tags: opensource, openeducation, openscience
Published: 2024-06-15 10:13:42


Apart from the fact that the vast majority of people use it in this way, relatively nothing supports the idea that « open source » is a software topic.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bcqq47tp9rucsshtr4jo.png)

We could be experiencing a paradigm shift in the meaning given to this concept, switching from software with an available source code to something around any type of digital resources whose sources are provided, in particular to enable modification.

From open source software to open source resources more broadly.

We see this terminology of "source(s)" being used to describe components from which resources are created, we see the notion of open source used outside of software to qualify their availability, and there is a tendency among a number of open source (software) specialists to agree that the use of the term outside software makes sense, in relatively unanimous terms.

« Open source » beyond software is already an existing reality.

We then have two coexisting meanings, between the more conventional one and the new one more restricted to specialised environments.

This makes it harder to know what open source truly is, it makes it harder to explain what it is, a concept that remains very vague and undetermined.

For the past month, discussions have been taking place with The Turing Way community about this confusion surrounding open source, to highlight this debate and see how it can be addressed in the book if appropriate.

Debates ensue as to whether we should follow a more conventional meaning or the more exotic one supported by experts, about whether to continue to introduce this as a software subject or not, about whether we are really facing an evolution of the concept or if new words are missing, the potential utility of this semantic evolution.

It's about introducing a contentious concept in evolution that we barely understand on top of political dissensus with people who have strong opinions and beliefs.

There is an ongoing discussion to create a new chapter for an Open Source (Re)Definition: https://github.com/the-turing-way/the-turing-way/pull/3705

See also the preview of the page proposal for open source: https://deploy-preview-3705--the-turing-way.netlify.app/reproducible-research/open/open-source

Open source could take on a new meaning that could render current conventions obsolete.
