tuohai666 commented on issue #3550: Timestamp miss milliseconds URL: https://github.com/apache/incubator-shardingsphere/issues/3550#issuecomment-560273550 I understand your concern. Actually, I checked all the versions as a condition in Connector/J, only 5.6.4 will cause critical troubles. That's why I chose this version. To explain why hardcode the version number, here are the reasons: 1. Databases mananged by one Sharding-Proxy instance may have different versions, there's no restricted conditions of the version consistency. In the inconsistent condition, which version should we choose? 2. Sharding-Proxy does not have different behaviors under different versions. Although we support alterable versions this time, we can't support alterable behaviors. For example, Sharding-Proxy didn't support MySQL protocol before 4.1. 3. It is not worthy to announce 'Sharding-Proxy can't work if the database versions aren't consistent' just for this issue. Anyway, I welcome you to submit a pull request, maybe your solution is better, we can discuss more there.
