Functions

func EncodeRowForRecord

func EncodeRowForRecord(ctx context.Context, encTable table.Table, sqlMode mysql.SQLMode, row []types.Datum, columnPermutation []int) string

EncodeRowForRecord encodes a row to a string compatible with INSERT statements.

func NewEncodingBuilder

func NewEncodingBuilder() backend.EncodingBuilder

NewEncodingBuilder creates an EncodingBuilder with TiDB backend implementation.

func NewTargetInfoGetter

func NewTargetInfoGetter(db *sql.DB) backend.TargetInfoGetter

NewTargetInfoGetter creates an TargetInfoGetter with TiDB backend implementation.

func NewTiDBBackend

func NewTiDBBackend(ctx context.Context, db *sql.DB, onDuplicate string, errorMgr *errormanager.ErrorManager) backend.Backend

NewTiDBBackend creates a new TiDB backend using the given database.

The backend does not take ownership of `db`. Caller should close `db` manually after the backend expired.
