Keyset API
Wrap representation of Spanner keys / ranges.
class google.cloud.spanner_v1.keyset.KeyRange(start_open=None, start_closed=None, end_open=None, end_closed=None)
Bases: object
Identify range of table rows via start / end points.
Specify either a start_open or start_closed key, or defaults to start_closed = []. Specify either an end_open or end_closed key, or defaults to end_closed = []. However, at least one key has to be specified. If no keys are specified, ValueError is raised.
Parameters
start_open (list of scalars) – keys identifying start of range (this key excluded)
start_closed (list of scalars) – keys identifying start of range (this key included)
end_open (list of scalars) – keys identifying end of range (this key excluded)
end_closed (list of scalars) – keys identifying end of range (this key included)
Raises
ValueError – if no keys are specified
_eq_(other)
Compare by serialized state.
class google.cloud.spanner_v1.keyset.KeySet(keys=(), ranges=(), all_=False)
Bases: object
Identify table rows via keys / ranges.
Parameters
keys (list of list of scalars) – keys identifying individual rows within a table.
ranges (list of
KeyRange) – ranges identifying rows within a table.all (boolean) – if True, identify all rows within a table
_eq_(other)
Compare by serialized state.
