Types

type BinlogDMLEvent

type BinlogDMLEvent struct {
	DatabaseName      string
	TableName         string
	DML               EventDML
	WhereColumnValues *sql.ColumnValues
	NewColumnValues   *sql.ColumnValues
}

BinlogDMLEvent is a binary log rows (DML) event entry, with data

func NewBinlogDMLEvent

func NewBinlogDMLEvent(databaseName, tableName string, dml EventDML) *BinlogDMLEvent

func (*BinlogDMLEvent) String

func (this *BinlogDMLEvent) String() string

type BinlogEntry

type BinlogEntry struct {
	Coordinates mysql.BinlogCoordinates
	EndLogPos   uint64

	DmlEvent *BinlogDMLEvent
}

BinlogEntry describes an entry in the binary log

func NewBinlogEntry

func NewBinlogEntry(logFile string, logPos uint64) *BinlogEntry

NewBinlogEntry creates an empty, ready to go BinlogEntry object

func NewBinlogEntryAt(coordinates mysql.BinlogCoordinates) *BinlogEntry

NewBinlogEntryAt creates an empty, ready to go BinlogEntry object

func (*BinlogEntry) Duplicate

func (this *BinlogEntry) Duplicate() *BinlogEntry

Duplicate creates and returns a new binlog entry, with some of the attributes pre-assigned

func (*BinlogEntry) String

func (this *BinlogEntry) String() string

String() returns a string representation of this binlog entry

type BinlogReader

type BinlogReader interface {
	StreamEvents(canStopStreaming func() bool, entriesChannel chan<- *BinlogEntry) error
