 # 1️⃣🐝🏎️ The One Billion Row Challenge
 
+_Status Jan 31: The challenge will close today at midnight CET. No new pull requests will be accepted after that time. Pending PRs will be evaluated over the next few days. Please don't push any changes to pending PRs after today, unless being asked to do so.
+This will be the case if I spot an issue during evaluation (failing tests, etc.). In this case, I will comment on the PR, and you are allowed to push one update.
+I will re-evaluate the entry, and if there are still remaining issues, you'll get one more and last opportunity to update the PR.
+If it still is not valid at this point, it will be closed.
+The final leader board will be published on Monday Feb 5._

 _Status Jan 12: As there has been such a large number of entries to this challenge so far (100+), and this is becoming hard to manage, please only create new submissions if you expect them to run in 10 seconds or less on the evaluation machine._
 
 _Status Jan 1: This challenge is [open for submissions](https://www.morling.dev/blog/one-billion-row-challenge/)!_
