func RetrieveTransactionResult(blockID flow.Identifier, transactionID flow.Identifier, transactionResult *flow.TransactionResult) func(pebble.Reader) error

func RetrieveTransactionResultByIndex 

func RetrieveTransactionResultByIndex(blockID flow.Identifier, txIndex uint32, transactionResult *flow.TransactionResult) func(pebble.Reader) error

func SetEpochEmergencyFallbackTriggered 

func SetEpochEmergencyFallbackTriggered(blockID flow.Identifier) func(txn pebble.Writer) error

SetEpochEmergencyFallbackTriggered sets a flag in the DB indicating that epoch emergency fallback has been triggered, and the block where it was triggered.

EFM can be triggered in two ways:

  1. Finalizing the first block past the epoch commitment deadline, when the next epoch has not yet been committed (see protocol.Params for more detail)
  2. Finalizing a fork in which an invalid service event was incorporated.

TODO: in pebble/mutator.go must implement RetrieveEpochEmergencyFallbackTriggeredBlockID and verify not exist Note: The caller needs to ensure a previous value was not stored

func SetJobLatestIndex 

func SetJobLatestIndex(queue string, index uint64) func(pebble.Writer) error

func SetProcessedIndex added in v0.37.1 

func SetProcessedIndex(jobName string, processed uint64) func(pebble.Writer) error

SetProcessedIndex updates the processed index for a job consumer with given index

func UpdateBlockChildren 

func UpdateBlockChildren(blockID flow.Identifier, childrenIDs flow.IdentifierList) func(pebble.Writer) error

UpdateBlockChildren updates the children for a block.

func UpdateClusterFinalizedHeight(clusterID flow.ChainID, number uint64) func(pebble.Writer) error

UpdateClusterFinalizedHeight updates the finalized boundary for the given cluster.

func UpdateComputationResultUploadStatus
