01:51:49 GMT <malignant2030> hello all, was hoping someone was available to help me with a problem really quickly
01:52:21 GMT <malignant2030> I'm looking for documentation on how Redis Sentinel generates the value for myid
09:39:37 GMT <Bhavin> Hi
09:40:14 GMT <Bhavin> WE are using redis on our production environment. However since few days we are facing issue.
09:40:36 GMT <Bhavin> due to out of memory in tomcat
09:41:33 GMT <Bhavin> This happens when session deserialisation starts it fill up the memory..
09:46:44 GMT <minus> introduce a memory limit or get more memory?
09:48:29 GMT <minus> both, the java VM and redis can be limited
10:04:11 GMT <Bhavin> 10GB is allocated to tomcat still it goes outofmemory
10:05:38 GMT <Bhavin> When Jedis read the session and passes to Struts it gets the outofmemory error which means size of object session is so large which results into OOME
14:41:49 GMT <yardenbar> Hi all, is there a way to stop redis persistence aof_rewrite_in_progress:1 ?
14:42:12 GMT <yardenbar> I've already set aof_enabled:0
15:54:54 GMT <yuppie> hello, anyone know how to share a redis connection between two python scripts?
16:15:39 GMT <amritoit> Hi
16:16:53 GMT <amritoit> I want to get one key like this - <key><{time,counter}> , and then I want to do some operation based on counter and again set it back to redis.
16:17:12 GMT <amritoit> Is there any better way to do it atomic?
16:19:06 GMT <Habbie> amritoit, can you explain a bit more? it is a bit vague
16:21:00 GMT <amritoit> Habbie: sorry for that. I have a key in redis which points to a json baically , the json is like this - {time:<epoche time>,count:<counter>}
16:21:50 GMT <amritoit> I want to fetch this json from redis and then based on I want to call one function and then again set back the json to redis by updating counter
16:22:48 GMT <amritoit> so there is one redis read, some operation, one redis write , and I want to do atomic
16:23:14 GMT <Habbie> i know what atomic means in general, but what does it mean in this case?
16:23:28 GMT <Habbie> do you want to say 'increase count by 10 and set time to now'?
16:25:36 GMT <Habbie> if so, either Transactions or EVAL(SHA) would work
16:25:40 GMT <amritoit> Habbie:yea, exactly thats my goal
16:26:31 GMT <amritoit> Habbie:I want to say set the counter and set the time
16:27:27 GMT <Habbie> to two values decided by the client?
16:27:41 GMT <amritoit> yea
16:37:02 GMT <amritoit> Any reference please?
16:37:59 GMT <Habbie> Transactions, EVAL, EVALSHA
16:38:08 GMT <Habbie> you still haven't explained to me what you mean by 'atomic' though
16:39:15 GMT <amritoit> Habbie:atomic means I am fetching the pair from redis , and doing some thing and then again writing back to redis
16:40:35 GMT <amritoit> Habbie:now lets say one thread is reading even before the previous is completed, then there will be an inconsistancy with the counter right?
16:40:43 GMT <Habbie> yes
16:40:50 GMT <Habbie> but what do you -want- in that case?
16:41:17 GMT <amritoit> So I want all the threads reads correct updated value
16:41:39 GMT <amritoit> it should not read the old counter in any scenario
17:01:21 GMT <fbred> does redis cluster support standby slaves? I have 8 physical nodes, 4 master and 4 slaves, but I realize that two nodes crash, and i'm unlucky, my cluster will break. Is it possible to have a idle instances that will act as a slave should one master ever get less than 0 slave?
17:05:39 GMT <lemonsparrow> Im a complete newbie.. just wanted to understand if there is any relationship between websockets and redis pub/sub
17:06:02 GMT <lemonsparrow> I am trying to develop a realtime document editor over websockets implementing operational transformation !
17:06:22 GMT <lemonsparrow> redis is used to store the data in memory
17:06:34 GMT <lemonsparrow> how can I use redis pub/sub to scale my application ?
17:18:46 GMT <Habbie> lemonsparrow, there is no relation
17:18:58 GMT <Habbie> lemonsparrow, but i'm sure people have made gateways for connecting websockets to redis pub/sub
17:19:17 GMT <Habbie> amritoit, i still don't understand exactly, but I suggest you look at the doc sections 'Transactions' and 'EVAL'
17:19:45 GMT <lemonsparrow> Habbie: I see in node they do like var client = redis.createClient() is this redis node module internally using websocket ?
17:20:30 GMT <Habbie> lemonsparrow, that would be without websocket, just using TCP or Unix sockets
17:20:58 GMT <lemonsparrow> Habbie: that comes in the server end I believe.. yes thats in the server
17:21:07 GMT <Habbie> yes
17:21:10 GMT <Habbie> node runs on the server
17:24:31 GMT <lemonsparrow> Habbie: ok
