Types

type ExecutionDataCache

type ExecutionDataCache struct {
	// contains filtered or unexported fields
}

ExecutionDataCache is a read-through cache for ExecutionData.

func NewExecutionDataCache

func NewExecutionDataCache(
	backend execution_data.ExecutionDataGetter,
	headers storage.Headers,
	seals storage.Seals,
	results storage.ExecutionResults,
	cache mempool.ExecutionData,
) *ExecutionDataCache

NewExecutionDataCache returns a new ExecutionDataCache.

func (*ExecutionDataCache) ByBlockID

func (c *ExecutionDataCache) ByBlockID(ctx context.Context, blockID flow.Identifier) (*execution_data.BlockExecutionDataEntity, error)

ByBlockID returns the execution data for the given block ID.

Expected errors during normal operations: - storage.ErrNotFound if a seal or execution result is not available for the block - BlobNotFoundError if some CID in the blob tree could not be found from the blobstore - MalformedDataError if some level of the blob tree cannot be properly deserialized - BlobSizeLimitExceededError if some blob in the blob tree exceeds the maximum allowed size

func (*ExecutionDataCache) ByHeight

func (c *ExecutionDataCache) ByHeight(ctx context.Context, height uint64) (*execution_data.BlockExecutionDataEntity, error)

ByHeight returns the execution data for the given block height.

Expected errors during normal operations: - storage.ErrNotFound if a seal or execution result is not available for the block - BlobNotFoundError if some CID in the blob tree could not be found from the blobstore - MalformedDataError if some level of the blob tree cannot be properly deserialized - BlobSizeLimitExceededError if some blob in the blob tree exceeds the maximum allowed size

func (*ExecutionDataCache) ByID

func (c *ExecutionDataCache) ByID(ctx context.Context, executionDataID flow.Identifier) (*execution_data.BlockExecutionDataEntity, error)

ByID returns the execution data for the given ExecutionDataID.

Expected errors during normal operations: - BlobNotFoundError if some CID in the blob tree could not be found from the blobstore - MalformedDataError if some level of the blob tree cannot be properly deserialized - BlobSizeLimitExceededError if some blob in the blob tree exceeds the maximum allowed size

func (*ExecutionDataCache) LookupID

func (c *ExecutionDataCache) LookupID(blockID flow.Identifier) (flow.Identifier, error)

LookupID returns the ExecutionDataID for the given block ID.

Expected errors during normal operations: - storage.ErrNotFound if a seal or execution result is not available for the block
