BlockResults Pruning #148
Description
Since #142, block results are stored each blocks to the rollkit db.
This will grow to infinity, so a pruning strategy must be introduced.
Two options were mentioned in our call:
- query x/network module for latest validated epoch, prune everything before that
- when x/network and the validator network isn't used (query fails), use a good value.
- Some food for thoughts, looking at the cometbft v1+ pruning service: https://github.com/cometbft/cometbft/blob/e1a860489ecc91290453487e08863a037f828c6d/rpc/grpc/server/services/pruningservice/service.go#L141
Given the blocks results are saved in the rollkit db, we must be sure that it doesn't overlap with evstack/ev-node#2093.
