PruneStage

reth_stages::stages

Struct PruneStage 

Source 
pub struct PruneStage { /* private fields */ }
Expand description

The prune stage that runs the pruner with the provided prune modes.

There are two main reasons to have this stage when running a full node:

  • Sender Recovery stage inserts a lot of data into the database that’s only needed for the Execution stage. Pruner will clean up the unneeded recovered senders.
  • Pruning during the live sync can take a significant amount of time, especially history segments. If we can prune as much data as possible in one go before starting the live sync, we should do it.

commit_threshold is the maximum number of entries to prune before committing progress to the database.
