Some other features that are not making it to this release are support for stored procedures, type-conversions, enums and bulk updates.

在这次发布中其他一些特性也没有达到预定目标，如对存储过程、类型转换、枚举和大数据块更新的支持。

If updates to the coordinate columns are possible, you may still be able to avoid bulk copies if the source table contains a time stamp column that records the time of last update for each row.

如果可能更新坐标列，但是源表包含一个时间戳列，其中记录了每行最后一次更新的时间，那么仍然可以避免批量复制。
