Answer 1

一种选择是，如果数据不是太大，则将其存储为字符串，否则将其分解为映射到sqlite的架构，并在加载时重新创建它。

Answer 2

If your XML data is large, I would rather change the data exchange type to json. XML parsing and then insert is a very expensive operation and is time-consuming.

Some issues which you will face with XML parsing and insert.

a. XML parsing is memory intensive and so you heap size will grow, you need to keep an eye on this as this might cause crash. b. Inserts in SQLite DB will take around ~100ms per tuple (row), so you can calculate the time it will required to pump in thousands of rows of data.

If you data is not too large don't bother about using SQLite.
