Index

public string Index { get; set; }

If non-empty, the name of an index on [table][google.spanner.v1.PartitionReadRequest.table].

KeySet

public KeySet KeySet { get; set; }

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].
