在相同事务下对“可重复读取”区域内数据的多次请求的结果是相同的，但能够带来更好的应用吞吐量。

With the "Repeatable Read" data region fetch requests issued multiple times within the same transaction will always produce the same result yielding better application throughput.

比如，读取只读的查找表不需要可重复读级别，未提交读级别就足够了。

For example, reading from a read - only look up table doesn t require repeatable read, and uncommitted read is sufficient.
