Hold my context! #1
Conversation
| The talk will describe different solutions people have been using (and | ||
| abandoning) over the past 6+ years, dive into history of domains and async | ||
| hooks, explain what's so difficult about context keeping, and finally offer | ||
| bright future that's coming with the recently introduced `AsyncLocalStorage` API. |

I don't know if Vladimir thinks the future is bright! nodejs/TSC#807

Good point. My impression was that nodejs/node#26540 is on a good way to get landed soon. I'll mention in the abstract that the final message of my talk my change depending on the outcome of current discussions in Node.js core.

| 4. Explain why is it difficult to preserve the context, a.k.a. "connection pool | ||
| problem". Talk about our own experience with issues caused by MongoDB driver. | ||
| Mention other use cases affected by this problem (APM tools like NewRelic). |

Promises are a huge problem as well. Google's native promises have support for async hooks, forced to be added by Node.js, but thirdparty promises don't, so any non-native thenable breaks the async continuation. Apparently, its particularly common for DB drivers.

looks like an interesting talk to me
What about applying for the Austin NodeConf with it as well?
