05:01:33 GMT <dudeji> does all key slots are fixed inside any cluster, i mean , can I not store more than 16384 keys in one of master node ?
05:01:36 GMT <gitgud> hey i have a question. if i use redis and use LRU system and set a max memory of say half of the RAM. what happens when the OS needs more than half of the RAM to do something else, does redis take more priority? or the other OS's tasks that it has to deal with?
05:02:49 GMT <dudeji> gitgud , i would suggest take small instance and keep it reserve for redis only , 4core and 8GB ram would be great even for cluster. 3core 4gb good enough for single node cluster.
05:03:08 GMT <dudeji> 2*core not 3core
05:04:11 GMT <gitgud> well thats not an option for the business right now. i have a big dedicated server and i'd like to put both redis and another database on this
08:03:38 GMT <badboy_> dudeji: nothing limits the number of keys besides the amount of memory you have available
08:03:45 GMT <badboy_> dudeji: you can store multiple keys per slot
12:53:33 GMT <dudeji> just some clarification : in cluster mode i will send data to one node , that node will return me correct node for key , then i will save data to that node , am i correct ?
12:53:58 GMT <dudeji> and how does cluster topology helps here ?
14:59:55 GMT <squadgoals> Hey for mget is the implication that the resulting at will come out the same order as the keys they were sent in?
15:00:23 GMT <squadgoals> Array*
15:00:31 GMT <squadgoals> Resulting array*
15:21:59 GMT <badboy_> squidgoals: yes, otherwise it would be useless
15:22:15 GMT <squidgoals> Dope. Thanks
17:07:46 GMT <neouf> hello
17:09:14 GMT <neouf> do you know if we have issue between version nodeclient 2.4.2 et server 3.2 ?
17:09:31 GMT <neouf> should i upgrade or downgrade something ?
17:09:51 GMT <neouf> i see syscall between then, but client timeout
17:11:42 GMT <neouf> whois arnaud_
17:11:55 GMT <neouf> oups :)
18:48:57 GMT <Ron___> Hello.  Can someone point me to a simple example of using replication with 3.2.6?  I can't seem to get it working.  I am using a single VM, I set up a master on 9999 and a slave on 10000.  When I go to "slave on" I see the following on the master.
18:49:37 GMT <Ron___> slaveof (sorry)
18:49:38 GMT <Ron___> ./src/redis-cli -a foobar2 -p 10000 slaveof 192.168.121.134 9999 OK
18:49:54 GMT <Ron___> 3113:S 10 Jan 10:49:49.884 * MASTER <-> SLAVE sync started 3113:S 10 Jan 10:49:49.885 # Error condition on socket for SYNC: Connection refused 3113:S 10 Jan 10:49:50.893 * Connecting to MASTER 192.168.121.134:9999
18:50:46 GMT <Ron___> I started to debug with PSYNC but haven't found any documentation on how to use it manually, it requires some arguments that are not documented (in the help, autocomplete)
18:58:32 GMT <Ron___> Dang, I see the issue, the bind is incorrect....
19:01:46 GMT <Ron___> Still, if anyone can give me a tip on PSYNC (via telnet) to how to manually do it that be cool!
19:05:32 GMT <minus> slaveof 127.0.0.1 9999 would've worked just fine without changing the bind
19:35:14 GMT <Circuitsoft> Hello - new to Redis here. Wondering about a certain architecture:
19:35:27 GMT <Circuitsoft> Client -> Redis: "Get Key x" (key x does not exist)
19:35:51 GMT <Circuitsoft> Redis -> Another process "Get key x"; ThisProc -> Redis: x_value; Redis -> Client: x_value
19:39:44 GMT <Circuitsoft> https://www.planttext.com/plantuml/svg/Syx9JCqhKT2rKmXAJSaijb9mJorHy4wjL8ZWIimfWGWgv2GcPnS3HI0yeDhWrAAor29anH0H97F24dDAKu4IgNaf27tEODiGaW00 - A Diagram of what I'm hoping to do.
19:56:58 GMT <Ron___> @circuitsoft, not sure if there is a command but here our some ideas.  Use 'set k v nx' and then 'get k', if you need to do it in a single command, then maybe pipe?
19:59:02 GMT <Ron___> There is getset but no setget.
20:27:43 GMT <maxmatteo> hey everyone
20:48:13 GMT <maxmatteo> any tips on storing an mail inbox/folder/messages  system in redis
20:48:16 GMT <maxmatteo> like a webmail client
20:48:29 GMT <maxmatteo> hash for messages by folders with id, content etc..
20:48:55 GMT <maxmatteo> redissearch maybe for searching functionality ...
20:49:28 GMT <badboy_> depends a lot on how you need to access it ;)
20:50:39 GMT <maxmatteo> well lets say i want so store max 90 mails
20:50:47 GMT <maxmatteo> sorting by subject or date
20:51:14 GMT <maxmatteo> and of course some kind ob pagination like in sql  LIMIT/OFFSET
20:51:24 GMT <maxmatteo> account->folder->message
20:51:57 GMT <maxmatteo> usually i fetc changes via imap and then would like to add that to that list
20:52:04 GMT <maxmatteo> so it pops out the last one
20:52:10 GMT <maxmatteo> and adds new one ontop
20:52:59 GMT <maxmatteo> i thought  a single message should be something like key:  $uniqueMessageId  value-> hash  with from subject body and more meta attributes like seen / recenet etc
20:53:38 GMT <maxmatteo> it will have A LOT data so i thought gzcompress values (its mostly strings like text/htm)
20:54:08 GMT <maxmatteo> and i thought lua scripts are not right to map that sync/updating logic, because there will be much parallel acces
20:54:21 GMT <maxmatteo> and i heard it blocks everyhting else :D
20:55:30 GMT <badboy_> why not mysql/postgres?
20:57:00 GMT <maxmatteo> simply performance
20:57:12 GMT <maxmatteo> planning to use redislabs on some big machines
20:57:48 GMT <badboy_> you have to pay for that with a bit more complexity and upfront work to model your data
20:57:55 GMT <maxmatteo> i am looking at 5000reqs/sec
20:58:00 GMT <badboy_> and for 90 mails I guess mysql would be just as fast
20:58:12 GMT <badboy_> that's not that much...
20:59:24 GMT <maxmatteo> i am looking at about 1 millions users having latest 90 mails
20:59:28 GMT <maxmatteo> :D
20:59:50 GMT <maxmatteo> sry forgot that little detail
21:00:08 GMT <maxmatteo> for a small amount i would probably use sqlite for sure
21:00:13 GMT <maxmatteo> ;)
21:01:11 GMT <badboy_> I hope you have a good amount of RAM ;)
21:01:37 GMT <badboy_> (likely a combination of whatever sql store you favor and redis for caching might be a good idea)
21:05:52 GMT <maxmatteo> well right now i hit the imap servers directly
21:06:03 GMT <maxmatteo> and it sucks when using it from webmail/ajax perspective
21:06:10 GMT <maxmatteo> performance and stability vise
21:06:50 GMT <maxmatteo> thinking about to use rlec flash
21:07:46 GMT <maxmatteo> looks promising
