Fields

index: Option<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.

transaction: Option<TransactionSelector>

Read only snapshot transactions are supported, read/write and single use transactions are not.

key_set: Option<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.

partition_options: Option<PartitionOptions>

Additional options that affect how many partitions are created.

table: Option<String>

Required. The name of the table in the database to be read.

columns: Option<Vec<String>>

The columns of table to be returned for each row matching this request.
