09:29:36 GMT <tomaz_b> hi, can someone help me with just one or two newbie questions, please
09:30:45 GMT <tomaz_b> can I have within 1 instance implemented like 2 or 3 pubsub queues? and next to this... some sort of data type which would allow me to store AND APPEND JSON files?
09:31:52 GMT <tomaz_b> So I would like to store cca 1000 "buckets" each unique by some ID, and then I would like to have 2-3 pubsub queues?
09:32:05 GMT <tomaz_b> is this something that I can do with one redis setup?
09:44:14 GMT <tomaz_b> anybody?
10:49:53 GMT <badboy_> tomaz_b: you can have arbitrarily many pubsub channels
10:50:13 GMT <badboy_> and Redis doesn't care about what the data it is. It doesn't even know about json (for the most part)
10:50:21 GMT <badboy_> so you can store and append as you will
10:57:53 GMT <tomaz_b> @badboy_: thanks!
11:11:43 GMT <tomaz_b> pubsub channel exists if there is some client subscribed to it. BUT what if all clients are down... and I have publisher who publishes there ... all those messages are going to "/dev/null", right? Can I publish and before that do a check .. .if channel exists, otherwise create it?
11:32:19 GMT <minus> badboy_: which part of redis knows json?
11:33:20 GMT <badboy_> The lua interpreter has a json library included
11:33:41 GMT <badboy_> tomaz_b: yes, if no one is subscribed, messages are lost
11:34:00 GMT <badboy_> no, you can't "create" it other than having a client subscribed
12:12:51 GMT <tomaz_b> can I update a specific value inside of a set. My set would store/contain JSONs as string. Can I update 1 of those JSONs?
12:19:41 GMT <badboy_> elements in a set are unique
12:19:50 GMT <badboy_> updating means deleting the old one and adding a new one
12:57:31 GMT <vseslav> I'm curious how to deal with the situation, when I use Redis as a cache. I update database and then I update redis and it fails
12:58:02 GMT <vseslav> are there any patterns to cope with such a problem?
13:03:36 GMT <tomaz_b> I set few key:value pairs into HASH. I am trying to figure out how MATCH works, but without luck. I thought I would be able to "match" those values that contains <pattern>. So like.... hscan <hash name> 0 match "<pattern>*"
13:03:43 GMT <tomaz_b> this doesn't work
13:04:06 GMT <tomaz_b> values are strings (basically JSONs)
13:04:44 GMT <tomaz_b> I have a key value in this string (JSON) ... on which I would like perform a match.
13:07:15 GMT <badboy_> vseslav: what fails?
13:08:11 GMT <vseslav> badboy_, for example I have a code. First I get data and second I should update cache in redis. And the second operation fails
13:08:36 GMT <vseslav> or I update data in db and then I should update cache in redis.
13:09:11 GMT <badboy_> tomaz_b: MATCH only works on the field
13:09:58 GMT <badboy_> vseslav: that depends on your needs a bit
13:10:46 GMT <badboy_> try again a number of times; don't care and wait for it to expire anyway; explicitely try to delete the cache and try again later
13:12:06 GMT <vseslav> badboy_, I've been thinking about it. To use a queue.
13:12:44 GMT <vseslav> but I want use it as simple as I can
13:13:48 GMT <vseslav> without third-party services, queues and so on. Didn't want to reinvent a bike
14:04:26 GMT <vseslav> badboy_, anyway, thanks for answer!
23:21:44 GMT <bleb> I'm doing redisCommand("MGET %s", key); and the reply is an array object with one element which is a string "(null)"... However when I connect with redis_cli and type MGET <key> I get the expected number. What could be the problem?
