Reference documentation and code samples for the Google Cloud Spanner v1 API class Mutation.Types.Write.
Arguments to [insert][google.spanner.v1.Mutation.insert], [update][google.spanner.v1.Mutation.update], [insert_or_update][google.spanner.v1.Mutation.insert_or_update], and
[replace][google.spanner.v1.Mutation.replace] operations.
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
Mutations, 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].
