const (
	// CommitModeAsync - commit return true if commit success add to internal send buffer (but not sent to server)
	// now it is grpc buffer, in feature it may be internal sdk buffer
	CommitModeAsync = topicreaderinternal.CommitModeAsync // default

	// CommitModeNone - reader will not be commit operation
	CommitModeNone = topicreaderinternal.CommitModeNone

	// CommitModeSync - commit return true when sdk receive ack of commit from server
	// The mode needs strong ordering client code for prevent deadlock.
	// Example:
	// Good:
	// CommitOffset(1)
	// CommitOffset(2)
	//
	// Deadlock:
	// CommitOffset(2) - server will wait commit offset 1 before send ack about offset 1 and 2 committed.
	// CommitOffset(1)
