将键空间通知与键事件通知相结合

Question

我希望获得一个带有特定键和特定事件的键空间通知。就像我想要一个关键名称'foo'与事件'set'一起操作时的通知。有什么方法可以将两者结合起来

psubscribe '__keyevent@0__,__keyspace@0__:set foo'.

Answer 1

遗憾的是，您不必订阅事件和密钥空间通知，并过滤订阅者中的邮件。

Answer 2

K     Keyspace events, published with __keyspace@<db>__ prefix.
E     Keyevent events, published with __keyevent@<db>__ prefix.
g     Generic commands (non-type specific) like DEL, EXPIRE, RENAME, ...
$     String commands
l     List commands
s     Set commands
h     Hash commands
z     Sorted set commands
x     Expired events (events generated every time a key expires)
e     Evicted events (events generated when a key is evicted for maxmemory)
A     Alias for g$lshzxe, so that the "AKE" string means all the events.

字符串中应至少包含K或E，否则无论字符串的其余部分如何，都不会传递任何事件。 例如，为列表启用密钥空间事件，配置参数必须设置为Kl，依此类推。 字符串KEA可用于启用每个可能的事件。
