Note that column names\n    are case-insensitive according to the [DDL\n    docs](https://cloud.google.com/spanner/docs/data-definition-language#create_table).\n* Tests duplicate columns with the same case and different cases.\n* Removes duplicate column check in `asMap` because all `Mutation`s are\n    now guaranteed not to have duplicate columns. Removes corresponding test code too.","distinct":true,"url":"https://api.github.com/repos/skrulcik/google-cloud-java/commits/c580fc8bcc68b6d81b4e40aa6d3de4e23b492dd9"}]}
