Expand description

A signal to the persistence service that part of the tree state can be persisted.

Variants§

§

SaveBlocks(Vec<ExecutedBlock<N>>, Sender<Option<BlockNumHash>>)

The section of tree state that should be persisted. These blocks are expected in order of increasing block number.

First, header, transaction, and receipt-related data should be written to static files. Then the execution history-related data will be written to the database.

§

RemoveBlocksAbove(u64, Sender<Option<BlockNumHash>>)

Removes block data above the given block number from the database.

This will first update checkpoints from the database, then remove actual block data from static files.

§

SaveFinalizedBlock(u64)

Update the persisted finalized block on disk

§

SaveSafeBlock(u64)

Update the persisted safe block on disk
