Types ¶

type Store ¶

type Store struct {
	sync.Map
}

Store is the in-memory data structure that holds the offsets per stream

func New ¶

func New() *Store

New returns a new in memory store to persist the last consumed offset.

func (*Store) GetCheckpoint ¶

func (c *Store) GetCheckpoint(streamName, shardID string) (string, error)

GetCheckpoint determines if a checkpoint for a particular Shard exists. Typically, this is used to determine whether processing should start with TRIM_HORIZON or AFTER_SEQUENCE_NUMBER (if checkpoint exists).

func (*Store) SetCheckpoint ¶

func (c *Store) SetCheckpoint(streamName, shardID, sequenceNumber string) error

SetCheckpoint stores a checkpoint for a shard (e.g. sequence number of last record processed by application).
