Net::ReadTimeout Exception: timed out while waiting for more data

[jaswinder97]

I tried to set timeout as
Dalli::KeysMatch.config.telnet({ 'Timeout' => 200, 'Prompt' => /(^END$)/ })

But it doesn't work and

.keys(/agents/

always gives timeout error

Hi @jaswinder97.

Have you tried to connect to memcached host without this gem? Just to ensure it's not network related issues.

Example:

$ memcached -l 127.0.0.1 -p 11211 -m 64 -vv

$ telnet localhost 11211
Trying ::1...
Connected to localhost.
Escape character is '^]'.
get agents-1
VALUE agents-1 1 4
i
END
quit
Connection closed by foreign host.

@marcosgz I might be doing something wrong. is there any method to delete all keys under a namespace?

[marcosgz]

@jaswinder97 Memcached does not have a namespace or something like delete/query by wildcards. This project is just actually a workaround for this. But using telnet and a very large list of keys may not work correctly. I do not recommend using this gem in production.

Another good option of key-value db is Redis. And you can do something like:

redis-cli --scan --pattern your_namespace:* | xargs redis-cli del
