public sealed class KeySet : IMessage<KeySet>, IEquatable<KeySet>, IDeepCloneable<KeySet>, IBufferMessage, IMessage
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.
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.
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].
