## Problem We want to define the algorithm for safekeeper membership change. ## Summary of changes Add spec for it, several models and logs of checking them. ref https://github.com/neondatabase/neon/issues/8699
The specifications, models and results of running of them of the compute <-> safekeepers consensus algorithm for committing WAL on the fleet of safekeepers. Following Paxos parlance, compute which writes WAL is called (WAL) proposer here and safekeepers which persist it are called (WAL) acceptors.
Directory structure:
- Use modelcheck.sh to run TLC.
- MC*.tla contains bits of TLA+ needed for TLC like constraining the state space, and models/ actual models.
- Other .tla files are the actual specs.
Structure is partially borrowed from logless-reconfig, thanks to it.
