defmodule GoogleApi.Spanner.V1.Model.Mutation do
  @moduledoc """
  A modification to one or more Cloud Spanner rows.  Mutations can be
  applied to a Cloud Spanner database by sending them in a
  Commit call.

  ## Attributes

  *   `delete` (*type:* `GoogleApi.Spanner.V1.Model.Delete.t`, *default:* `nil`) - Delete rows from a table. Succeeds whether or not the named
      rows were present.
  *   `insert` (*type:* `GoogleApi.Spanner.V1.Model.Write.t`, *default:* `nil`) - Insert new rows in a table. If any of the rows already exist,
      the write or transaction fails with error `ALREADY_EXISTS`.
  *   `insertOrUpdate` (*type:* `GoogleApi.Spanner.V1.Model.Write.t`, *default:* `nil`) - Like insert, except that if the row already exists, then
      its column values are overwritten with the ones provided. Any
      column values not explicitly written are preserved.
  *   `replace` (*type:* `GoogleApi.Spanner.V1.Model.Write.t`, *default:* `nil`) - Like insert, except that if the row already exists, it is
      deleted, and the column values provided are inserted
      instead. Unlike insert_or_update, this means any values not
      explicitly written become `NULL`.
  *   `update` (*type:* `GoogleApi.Spanner.V1.Model.Write.t`, *default:* `nil`) - Update existing rows in a table. If any of the rows does not
      already exist, the transaction fails with error `NOT_FOUND`.
