# run pruning using config from app.toml

# run compacting
cyber-pruner compact

# run pruning with params
cyber-pruner prune --home ~/.cyber --pruning validator

# run compacting with params

Note: Application pruning can take a very long time dependent on the size of the db.

Flags:

• home: path to directory for config and data (default=~/.cyber)
• cosmos-sdk: If pruning a non cosmos-sdk chain, like Nomic, you only want to use tendermint pruning or if you want to only prune tendermint block & state as this is generally large on machines(Default true)
• tendermint: If the user wants to only prune application data they can disable pruning of tendermint data. (Default true)
• tx-index: If the user wants to prune the transaction and block events index (Default false)
• min-retain-blocks: set the amount of tendermint blocks to be kept (default=300000)
• pruning-keep-recent: set the amount of versions to keep in the application store (default=500000)
• pruning-keep-every: set the version interval to be kept in the application store (default=None)
• pruning: pruning profile (default "default")
• batch: set the amount of versions to be pruned in one batch (default=10000)
• parallel-limit: set the limit of parallel go routines to be running at the same time (default=16)
• compact: compact the stores after pruning (default=true)
