columns |
MutableSequence[str]
The names of the columns in table][google.spanner.v1.Mutation.Write.table] to be

values |
MutableSequence[google.protobuf.struct_pb2.ListValue]
The values to be written. values can contain more than
one list of values. If it does, then multiple rows are
written, one for each entry in values . Each list in
values must have exactly as many entries as there are
entries in
columns][google.spanner.v1.Mutation.Write.columns] above.
Sending multiple lists is equivalent to sending multiple
Mutation \ s, each containing one values entry and
repeating table][google.spanner.v1.Mutation.Write.table]
and columns][google.spanner.v1.Mutation.Write.columns] .
Individual values in each list are encoded as described
here][google.spanner.v1.TypeCode] .
