Struct sc_cli::PruningParams

pub struct PruningParams {
    pub state_pruning: Option<DatabasePruningMode>,
    pub blocks_pruning: DatabasePruningMode,
}

Parameters to define the pruning mode

Fields

state_pruning: Option<DatabasePruningMode>

Specify the state pruning mode. This mode specifies when the block’s state (ie, storage) should be pruned (ie, removed) from the database. This setting can only be set on the first creation of the database. Every subsequent run will load the pruning mode from the database and will error if the stored mode doesn’t match this CLI value. It is fine to drop this CLI flag for subsequent runs. Possible values:

• archive: Keep the state of all blocks.
• ‘archive-canonical’ Keep only the state of finalized blocks.
• number Keep the state of the last number of finalized blocks. [default: 256]

blocks_pruning: DatabasePruningMode

Specify the blocks pruning mode. This mode specifies when the block’s body (including justifications) should be pruned (ie, removed) from the database. Possible values:

• ‘archive’ Keep all blocks.
• ‘archive-canonical’ Keep only finalized blocks.
• number Keep the last number of finalized blocks.
