Transaction of TiKV adopts the model used by Google in BigTable: [Percolator](https://research.google.com/pubs/pub36726.html). TiKV's implementation is inspired by this paper, with a lot of optimizations. See [transaction overview](/transaction-overview.md) for details.

The linked research paper https://research.google.com/pubs/pub36726.html now redirects to 404.

2. How would you like to improve it?

It seems you need to access it by https://research.google.com/pubs/pub36726.html?source= instead — the ?source= part is mandatory to prevent Google from auto-redirecting to the non-existing https://ai.google/research/pubs/pub36726/.
