type Pruner ¶

type Pruner struct {
	component.Component
	// contains filtered or unexported fields
}

Pruner is a component responsible for pruning data from execution data storage. It is configured with the following parameters:

• Height range target: The target number of most recent blocks to store data for. This controls the total amount of data stored on disk.
• Threshold: The number of block heights that we can exceed the height range target by before pruning is triggered. This controls the frequency of pruning.

The Pruner consumes a stream of tracked height notifications, and triggers pruning once the difference between the tracked height and the last pruned height reaches the height range target + threshold. A height is considered fulfilled once it has both been executed, tracked, and sealed.
