Class PartitionReadRequest (3.40.1)

PartitionReadRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)

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


session str
Required. The session used to create the partitions.
Read only snapshot transactions are supported, read/write and single use transactions are not.
table str
Required. The name of the table in the database to be read.
index str
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 MutableSequence[str]
The columns of table][google.spanner.v1.PartitionReadRequest.table] to be returned for each row matching this request.
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.
Additional options that affect how many partitions are created.
