I3-bug The node fails to follow expected behavior. U2-some_time_soon Issue is worth doing soon. Z2-medium Can be fixed by a coder with good Rust knowledge but little knowledge of the codebase.

Currently AUX column in the polkadot database is over 1Gb in size. Out of 4.9m values most are small, but some 22208 are 50-100kbytes in size (See this comment for details). Small values are probably BABE block weights, that could be pruned on finality. Larger values are most likely slot equivocation detection data, which should be already pruned. So, there are two items here:

  1. Implement BABE block weight data pruning.
  2. Figure out the source for per-epoch storage values, and if there's an issue with slot pruning - fix it.
