Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ session	string Required. The session used to create the partitions.
↳ transaction	TransactionSelector Read only snapshot transactions are supported, read/write and single use transactions are not.
↳ table	string Required. The name of the table in the database to be read.
↳ index	string If non-empty, the name of an index on table. This index is used instead of the table primary key when interpreting key_set and sorting result rows. See key_set for further information.
↳ columns	array The columns of table to be returned for each row matching this request.
↳ key_set	KeySet Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in table to be yielded, unless index is present. If index is present, then key_set instead names index keys in index. It is not an error for the key_set to name rows that do not exist in the database. Read yields nothing for nonexistent rows.
