ComputeRecordSize ( Record record ) : long	A helper function to compute record size which equals the sum of the UTF-8 string length of record key and value. 0 if record is null.
GetIdentityId ( CognitoAWSCredentials credentials ) : string	A helper function to get the identity id of the dataset from credentials provider. If the identity id is null, UNKNOWN_IDENTITY_ID will be returned.
TruncateToSeconds ( System.DateTime dateTime ) : System.DateTime	A helper function to truncate a DateTime object to whole seconds.
ValidateDatasetName ( string datasetName ) : string	Validates the dataset name.
ValidateRecordKey ( string key ) : string	Validates the record key. It must be non empty and its length must be no greater than 128. Otherwise {@link IllegalArgumentException} will be thrown.
