Short: "Strip all blocks from the database outside of a given range",
2024-04-24 11:41:25 +00:00
Long: `shard opens a local 0g-chainhome directory's databases and removes all blocks outside a range defined by --start and --end. The range is inclusive of the end block.
It works by first rolling back the latest state to the block before the end block, and then by pruning all state before the start block.
Setting the end block to -1 signals to keep the latest block (no rollbacks).
The application.db can be loaded at a particular height via the --force-app-version option. This is useful if the sharding process is prematurely terminated while the application.db is being sharded.
The --only-app-state flag can be used to skip the pruning of the blockstore and cometbft state. This matches the functionality of the cosmos-sdk's "prune" command. Note that rolled back blocks will still affect all stores.
Similarly, the --only-cometbft-state flag skips pruning app state. This can be useful if the shard command is prematurely terminated during the shard process.
The shard command only flags the iavl tree nodes for deletion. Actual removal from the databases will be performed when each database is compacted.
WARNING: this is a destructive action.`,
2024-04-24 11:41:25 +00:00
Example: `Create a 1M block data shard (keeps blocks a0gi 1,000,000 to 2,000,000)
$ 0gchaind shard --home path/to/.0gchain --start 1000000 --end 2000000
Prune all blocks up to 5,000,000:
2024-04-24 11:41:25 +00:00
$ 0gchaind shard --home path/to/.0gchain --start 5000000 --end -1
Prune first 1M blocks _without_ affecting blockstore or cometBFT state:
2024-04-24 11:41:25 +00:00
$ 0gchaind shard --home path/to/.0gchain --start 1000000 --end -1 --only-app-state`,
