Expand description
Each time we make a new checkpoint, we will mark more data as garbage depending on the parameters. To avoid the GC process affecting normal transaction execution or RPC-handling, we GC data gradually, and expect to finish removing the data in a previous era with less time than the period that the consensus graph makes a new era (the default configuration is to finish GC with half an era).

Implementations§
source§impl GCProgress
impl GCProgress
pub fn new(next_to_process: u64) -> Self
sourcepub fn get_gc_base_range(&self, best_epoch: u64) -> Option<(u64, u64)>
pub fn get_gc_base_range(&self, best_epoch: u64) -> Option<(u64, u64)>
Compute the GC base range to make sure the GC progress is proportional
to the consensus progress.
The actual GC range for each kind of data is the returned base range
minus the corresponding additional_maintained*
offset.
Return Some((start_epoch, end_epoch))
and the range [start_epoch, end_epoch)
will be GCed. Return None
if there is no work to be
done.
