01:19:24 GMT <farsonic> ok, have python writing to my redis using walrus now
01:19:34 GMT <farsonic> can I dump the contents of the db using the redis cli?
01:19:44 GMT <farsonic> what to see what is happening as it is updated
01:29:43 GMT <farsonic> ah, worked it out
12:29:07 GMT <siddv29> Hi guys, i am new to redis DB. Could someone provide any tutorial link with deep dive in redis.
12:29:15 GMT <siddv29> I went through the redis.io tutorial
12:29:30 GMT <siddv29> would love to understand redis' architecture in much more detail
12:51:48 GMT <mrgreenfur> Anyone know how to set the sentinel log? I don’t see it in the conf examples/options anywhere
13:00:37 GMT <badboy_> mrgreenfur: logfile "path/to/your/file"
13:00:52 GMT <mrgreenfur> badboy_: oh, thats simple enough, thanks
13:01:44 GMT <mrgreenfur> the same with dir?
13:03:58 GMT <badboy_> well, given that Sentinel does not store any data, there is no use for dir
13:14:00 GMT <mrgreenfur> hrm, I see it autogenerates one, but maybe it’ sjust the config file it’s writing as it runs
15:21:40 GMT <mikereca> Is there a way to run a command on a key when it expires, and based on the output of that command, move the data out of redis or to another redis db?
15:22:00 GMT <badboy_> mikereca: no
15:22:13 GMT <mikereca> :( not even with a Lua plugin?
15:22:15 GMT <badboy_> you can in theory listen to keyspace notifications, but that won't give you the actual data
15:22:19 GMT <badboy_> no, no lua plugins either
15:22:22 GMT <mikereca> ah
15:23:03 GMT <Habbie> duplicate your expiring data into a non-expiring key (or with a longer expiry) and use the second key from your namespace notification
15:23:12 GMT <Habbie> s/duplicate/indirect/ if you want to save RAM
15:25:17 GMT <mikereca> @Habbie: that might actually work pretty well
15:25:31 GMT <Habbie> :)
15:28:23 GMT <mikereca> @Habbie: you can't do a lookup on an expiring key, right?
15:32:10 GMT <Habbie> mikereca, no, but you could do key and _key so you can always find the other one by just prepending _
15:32:16 GMT <Habbie> mikereca, this is a very rough idea to be clear, i haven't done this
15:37:58 GMT <mikereca> Habbie, I'll let this simmer for a bit. Thanks for your and @badboy_'s help!
19:11:13 GMT <JrWebDev> wahts the best way to use a nosql like redis.  say i have some data in my database.  Would i use some kinda of cron job to update the redis from database every week? or simply manually input key,values into redis and exclude from database?
19:13:58 GMT <minus> the way we do it: primary data in postgres, trigger functions attached to tables which emit a NOTIFY, a custom daemon that connects to postgres and redis and listens to those notifications and writes the data to redis (explanation simplified)
19:14:43 GMT <JrWebDev> awesome minus
19:15:03 GMT <minus> you don't have to do it that complicated, but you're not gonna get past writing/using a daemon like that
19:15:31 GMT <JrWebDev> you create a daemon based off linux terminal
19:15:44 GMT <JrWebDev> to listen to postgre and redis
19:16:02 GMT <minus> the daemon's written in python (with twisted)
19:16:10 GMT <JrWebDev> i see
19:16:55 GMT <minus> the simplest way is, as you already suggested, to run a cron job that runs a script that copies the data
19:17:21 GMT <minus> if your database items have modification dates you can use those to do incremental updates
19:17:43 GMT <JrWebDev> thats true
19:17:54 GMT <JrWebDev> idk if php supports redis very well
19:18:21 GMT <JrWebDev> or actually..i should just use linux bash to communicate between mysql and redis with a cron job
19:18:23 GMT <minus> there's at least 2 libraries for it
19:18:36 GMT <minus> nah, bash won't quite work
19:18:44 GMT <JrWebDev> darn
19:18:45 GMT <minus> php is fine
19:18:54 GMT <JrWebDev> the thing is..
19:19:25 GMT <JrWebDev> if i use php.  do i set it up to run at certain times?  the way i think of php is that once php is loaded it'll run...unless of course i give it a timer
19:20:25 GMT <minus> well, you can either start the script every x minutes via a cronjob or just write a daemon in php too
19:37:43 GMT <JrWebDev> thats true
19:38:08 GMT <JrWebDev> good idea.  okay just wondering how its done out there in the real world.  im totally new to no sql so wasnt sure what was the best practices out there.
20:44:23 GMT <maxmatteo> i can highly recommend predis for php
