KeySet(mapping=None, *, ignore_unknown_fields=False, **kwargs)KeySet defines a collection of Cloud Spanner keys and/or key
ranges. All the keys are expected to be in the same table or index.
The keys need not be sorted in any particular way.
If the same key is specified multiple times in the set (for example if two ranges, two keys, or a key and a range overlap), Cloud Spanner behaves as if the key were only specified once.

| Name | Description |
keys |
MutableSequence[google.protobuf.struct_pb2.ListValue]
A list of specific keys. Entries in keys should have
exactly as many elements as there are columns in the primary
or index key with which this KeySet is used. Individual
key values are encoded as described
here][google.spanner.v1.TypeCode].
|
ranges |
MutableSequence[google.cloud.spanner_v1.types.KeyRange]
A list of key ranges. See KeyRange][google.spanner.v1.KeyRange] for more information
about key range specifications.
|
all_ |
bool
For convenience all can be set to true to indicate
that this KeySet matches all keys in the table or index.
Note that any keys specified in keys or ranges are
only yielded once.
