1、flyfish的设计目标就是针对游戏中最普遍的数据访问模式提供一套可靠的kv缓存系统。真正的落地数据库并不一定必须是sql数据库,例如使用tikv作为数据库也是可以的。所以如果应用涉及大量关系数据库的操作,直接选择成熟的分布式关系数据系统更合适。
2、flyfish是一个分布式缓存,事务中操作的多个kv可能被缓存在多个分片上,所以要实现事务的话就必须实现分布式事务。这一块我暂时还没有考虑好用什么方案实现。不过这块跟db事务应该没关系,因为数据回写都是异步的。只要把flyfish作为统一的数据访问接口,flyfish中的数据最终跟db上的数据将达成一致。
3、目前就是这样的设计,如果在回写过程中发生不可重试性错误,本次任务就不再尝试了,但是并没有把kv的dirty标记清除,也就是下次再触发回写时,之前变更的内容还会再次尝试回写回去。之所以这么设计是因为,如果flyfish先使用了新配置,例如增加了一个字段,而数据库还未应用新的配置,此时回写肯定会失败的。如果后面数据库更新了配置,那么之后的回写就会成功。
