大多数的 Redis 兼容服务还是采用了轻量锁的方案,这样比较容易做到兼容,Dragonfly 的实现是参考了《VLL: a lock manager redesign for main memory database systems》[[7]](https://zhuanlan.zhihu.com/p/584485562#ref_7)里的 VLL 方案。不过从支持的接口[[8]](https://zhuanlan.zhihu.com/p/584485562#ref_8)列表看,Dragonfly 尚未完全兼容 Redis 的接口。 https://zhuanlan.zhihu.com/p/584485562 为了提供对多键并发操作的原子性保证,我们使用了最近学术研究的进展。我们选择了论文 ["VLL: a lock manager redesign for main memory database systems”](https://www.cs.umd.edu/~abadi/papers/vldbj-vll.pdf)...

I add tracing , but not display sql i use export RUST_LOG=debug ``` use atty::Stream; use tracing_subscriber::{fmt::format::Writer, layer::SubscriberExt, EnvFilter}; pub struct NoTime; impl tracing_subscriber::fmt::time::FormatTime for NoTime { fn format_time(&self, _writer:...

是的,参见 https://dev.mysql.com/doc/refman/8.0/en/data-type-defaults.html Now, with MySQL v8+, you can to do this just in parentheses: CREATE TABLE t1 ( -- literal defaults i INT DEFAULT 0, c VARCHAR(10) DEFAULT '', --...
