Functions ¶
func LoopPruneExecutionDataFromRootToLatestSealed ¶
func LoopPruneExecutionDataFromRootToLatestSealed( ctx context.Context, log zerolog.Logger, metrics module.ExecutionMetrics, state protocol.State, badgerDB *badger.DB, headers storage.Headers, chunkDataPacks storage.ChunkDataPacks, results storage.ExecutionResults, chunkDataPacksDB *pebble.DB, config PruningConfig, ) error
func NewChunkDataPackPruningEngine ¶
func NewChunkDataPackPruningEngine( log zerolog.Logger, metrics module.ExecutionMetrics, state protocol.State, badgerDB *badger.DB, headers storage.Headers, chunkDataPacks storage.ChunkDataPacks, results storage.ExecutionResults, chunkDataPacksDB *pebble.DB, config PruningConfig, ) *component.ComponentManager
NewChunkDataPackPruningEngine creates a component that prunes chunk data packs from root to the latest sealed block.
Types ¶
type ChunkDataPackPruner ¶
type ChunkDataPackPruner struct {
*pruners.ChunkDataPackPruner
}
func NewChunkDataPackPruner ¶
func NewChunkDataPackPruner(chunkDataPacks storage.ChunkDataPacks, results storage.ExecutionResults) *ChunkDataPackPruner
func (*ChunkDataPackPruner) ExecuteByBlockID ¶
func (c *ChunkDataPackPruner) ExecuteByBlockID(blockID flow.Identifier, batch storage.ReaderBatchWriter) (exception error)
type LatestPrunable ¶
type LatestPrunable struct {
*latest.LatestSealedAndExecuted
// contains filtered or unexported fields
}
LatestPrunable decides which blocks are prunable we don't want to prune all the sealed blocks, but keep a certain number of them so that the data is still available for querying
type PruningConfig ¶
type PruningConfig struct {
Threshold uint64 // The threshold is the number of blocks that we want to keep in the database.
BatchSize uint // The batch size is the number of blocks that we want to delete in one batch.
SleepAfterEachBatchCommit time.Duration // The sleep time after each batch commit.
SleepAfterEachIteration time.Duration // The sleep time after each iteration.
}
