然后，我继续添加测试，每次通过添加新代码、变更现有代码及重新分解的方式来修改代码。
Then, I continue to add tests, each time modifying the code by adding new code, changing existing code, and refactoring as I go.
另一种方式是使用带注释的模式分解将所有新文档分解到现有的副表，只修改列类型而不删除副表。
An alternate approach could be to use an annotated schema shred to decompose all new documents to existing side tables, and only change the column type without dropping the side tables.
一旦将字符串分解成序列，就可以用新的序列操作函数如insert - before来修改它。
Once you separate the string into a sequence, you can also use the new sequence-manipulation functions, such as insert-before , to alter it.
在这个场景中，修改了表模式，完全删除了副表和一些分解的列。
In this scenario, you modified the table schema and completely dropped the side tables and some of the shredded columns.
