Types

type Change added in v0.3.0 

type Change struct {
	// Before contains the data before the operation occurred. This field is
	// optional and should only be populated for operations OperationUpdate
	// OperationDelete (if the system supports fetching the data before the
	// operation).

	// be populated for all operations except OperationDelete.
	After Data `json:"after"`
}

	// operation, the record will contain either the payload before the change,
	// after the change, or both (see field Payload).
	Operation Operation `json:"operation"`
	// Metadata contains additional information regarding the record.
	Metadata Metadata `json:"metadata"`

	// Key represents a value that should identify the entity (e.g. database
	// row).
	Key Data `json:"key"`
	// Payload holds the payload change (data before and after the operation
	// occurred).
	Payload Change `json:"payload"`
