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

for further information.

returned for each row matching this request.

key_set |
google.cloud.spanner_v1.types.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.
