The request for [PartitionRead][google.spanner.v1.Spanner.PartitionRead]

Fields

session: String

Required. The session used to create the partitions.

transaction: Option<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][google.spanner.v1.PartitionReadRequest.table]. This index is used instead of the table primary key when interpreting [key_set][google.spanner.v1.PartitionReadRequest.key_set] and sorting result rows. See [key_set][google.spanner.v1.PartitionReadRequest.key_set] for further information.

columns: Vec<String>

The columns of [table][google.spanner.v1.PartitionReadRequest.table] to be returned for each row matching this request.

key_set: Option<KeySet>

Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in [table][google.spanner.v1.PartitionReadRequest.table] to be yielded, unless [index][google.spanner.v1.PartitionReadRequest.index] is present. If [index][google.spanner.v1.PartitionReadRequest.index] is present, then [key_set][google.spanner.v1.PartitionReadRequest.key_set] instead names index keys in [index][google.spanner.v1.PartitionReadRequest.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.
