Release Notes

• Breaking Changes

  • refactor Read to return ReadResult; remove ResultSet (#935)
  • removed Row<> from mutations API (#938). Removes the AddRow(Row<Ts...>)
    member function on the WriteMutation API. In place of this method there
    is now an AddRow(std::vector<Value>) method.
  • Change Value::Bytes to google::cloud::spanner::Bytes (#920)
  • implement CreateInstanceRequestBuilder (#933). Changed the function
    signature of InstanceAdminClient::CreateInstance().
  • Replace ExecuteSql with ExecuteQuery and ExecuteDml (#927)
  • Changed RowParser to require a Row<Ts...> template param (#653).
    ResultSet::Rows used to be a variadic template that took the individual
    C++ types for each row. With this change that function is now a template
    with one parameter, which must be a Row<...> type.
  • Implements Database in terms of Instance (#652). This PR removes
    renames some accessors like InstanceId -> instance_id due to their
    trivial nature now (style guide). It also removes some methods like
    Database::ParentName(), which is now replaced by Database::instance().
  • Fixes inconsistent naming of the Batch DML params struct. (#650). This
    struct has been renamed, so any code using this struct will need to be
    updated.

• Feature changes

  • implement InstanceAdminClient methods CreateInstance, UpdateInstance,
    DeleteInstance, ListInstanceConfigs, GetInstanceConfig,
    SetIamPolicy.
  • implement DatabaseAdminClient methods TestIamPermissions,
    SetIamPolicy, GetIamPolicy.
  • implement retries for Commit(), PartitionRead, PartitionQuery,
    ExecuteBatchDml, CreateSession, Rollback.
  • implement PartialResultSetRead with resumes (#693)
  • use separate policies for retry vs. rerun (#667)
  • implement DatabaseAdminConnection (#638)
  • implement overloads on UpdateInstanceRequestBuilder (#921)
  • implement metadata decorator for InstanceAdminStub. (#678)
  • implement logging wrapper for InstanceAdminStub. (#676)
  • support install components for the library (#659)

• Bug fixes

  • fix runtime install directory (#658)
  • give sample programs a long timeout time. (#622)
  • use RunTransaction for read write transaction sample (#654)
