根因分析

两个并发事务尝试修改同一文档，导致一个事务因乐观并发控制而中止。

English

Two concurrent transactions attempted to modify the same document, causing one to abort due to optimistic concurrency control.

官方文档

解决方案

  1. Implement a retry loop in the application: catch the write conflict error and re-run the transaction up to 3 times with exponential backoff.
  2. Reduce transaction scope by accessing fewer documents or using smaller batch sizes to minimize contention.
  3. Use a deterministic ordering for document updates within transactions to prevent deadlocks and conflicts.

无效尝试

常见但无效的做法:

  1. 50% 失败

    Disabling transactions entirely removes atomicity guarantees for multi-document operations.

  2. 50% 失败

    Increasing wtimeoutMS does not resolve write conflicts; it only affects write concern timeouts.

  3. 50% 失败

    Setting retryWrites=true does not apply to transactions; transactions must be retried manually.
