SwissTable: A High-Performance Hash Table Implementation
Currently, the official implementation of swisstable in Go is still under discussion, and there are a few community implementations like concurrent-swiss-map and swiss. However, they are not perfect; in small map scenarios, swisstable may even underperform compared to runtime_map. Nonetheless, the potential demonstrated by swisstable in other languages indicates that it is worth anticipation.

Ask HN: When would you fork instead of waiting for proposal/PR acceptance?
I love Go's templating system for its simplicity and frankly being part of the stdlib. I am however in need of a parser extensions. I created a proposal for this (https://github.com/golang/go/issues/59453), but like many large open source projects, the proposal queue is substantial with uncertain review timelines. I'm considering forking just this part of the stdlib to implement my needed changes in a backward-compatible way.
This raises a broader question: At what point do you decide to fork and maintain your own version versus waiting for upstream acceptance? What has been your experience with similar situations, especially when dealing with core libraries or language features?
I guess one sure reason to fork it is if the proposal is completely shot down and for some reason the proposer absolutely cannot live without it - but let us not go that far!

Go Upgrade Checklist
If you're working at a large company and downtime is extremely expensive, this checklist is a good guide. Otherwise, if you have good test coverage, you can get by with something simpler. It's super rare to have a breaking change in go.
We do quarterly upgrades of all services in a monorepo (about 20-30). The steps are basically this:
- Upgrade all dependencies to their latest versions, fixing build and test breaks (I read release notes for Go, but not for dependencies)
- Look for deprecated packages and replace them
- Upgrade all toolchains, including CI/CD containers, go.mod, etc.
- Run all tests
- Deploy to the test environment and make sure everything is green
- Deploy to staging and do some sanity checks
- Deploy to prod, keeping an eye on metrics for an hour or two
We're on k8s and the state of all clusters (i.e. which images are running) is tracked in git, so a rollback is just git revert + apply.
In practice, after about four years of this, we've seen maybe a dozen build breaks, and I can only remember one regression caused by a breaking change in a library[1].
