01:14:44 GMT <berndj> hiredis has redisContext *redisConnect(const char *ip, int port); - is that really only allowed to be an IP address (IPv4 only or does it also understand IPv6?) or will it also accept a hostname and resolve it?
07:33:47 GMT <badboy_> berndj: it resolves and works just fine with IPv6
07:42:00 GMT <psprint> Hello. Is it possible to list all keys that aren't special objects (sets, sorted sets, lists)
07:43:36 GMT <badboy_> No
07:43:40 GMT <psprint> it looks like redis has regular DBM-like key-value storage, and possibly sub-storages, that are lists, hashes, etc.
07:43:44 GMT <badboy_> Apart from that they are nowhere near "special"
07:44:02 GMT <badboy_> Redis is a key-value store where the value can be of different types, yes
07:44:24 GMT <psprint> I cannot do "GET alist"
07:44:39 GMT <badboy_> that is correct. Each value has its own specific commands.
07:47:19 GMT <psprint> I'm thinking about a mapping tool, between programming language hash-array, and redis main storage key->binary_value. This seems somewhat doable, except database might be changed outside, so cache/nocache use cases arise. However, don't know what to do with lists, sets, etc. Is there a library that does such mappings, for some programming language?
07:49:20 GMT <badboy_> afaik there is one for Python
07:59:31 GMT <psprint> in hiredis, I don't see read/write options, i.e. to connect in e.g. read-only mode. There is no such distinction in redis, or does hires not support it (or I look in wrong place) ?
08:03:34 GMT <psprint> I can issue READONLY after connecting
08:05:20 GMT <psprint> (error) ERR This instance has cluster support disabled
08:07:37 GMT <badboy_> There is no such distinction
08:07:44 GMT <badboy_> Just don't send write commands
08:08:04 GMT <badboy_> READONLY is indeed cluster specific, as by default Cluster disallows reads from slaves
08:09:31 GMT <valhala_22> how can i get all the hashes
08:09:50 GMT <valhala_22> is there some command when i use HGETALL * i get empty list
08:13:24 GMT <badboy_> valhala_22: You can't
08:13:40 GMT <valhala_22> ok
08:13:58 GMT <badboy_> In general there are only two commands that will get you all keys (KEYS and SCAN). KEYS is really expensive, and even when you reach for SCAN you should rethink your approach
08:14:14 GMT <badboy_> Plus you will always need to filter for keys with the right type later on
08:15:11 GMT <valhala_22> right now i am on dev server doesnt contain not more than 30 hashes
08:27:35 GMT <brijesh_learner> redis in a persistence mode also save the same keys stored in disk into RAM as well ?
09:16:23 GMT <Olive6767> Hi All :)
09:18:49 GMT <Olive6767> I have live redis service that I would preffer to maintain online. However I would like to restore 2 keys out of a backup redis dump. Is there a way to do so while keeping my current redis service live?
10:05:44 GMT <badboy_> valhala_22: use KEYS, but only in dev ever.
10:05:53 GMT <badboy_> brijesh_learner: yes, Redis always keeps all the data in memory
10:06:18 GMT <valhala_22> yeah i used  already KEYS   ,anyways ty
10:06:44 GMT <badboy_> Olive6767: from an rdb file? You can always extract the data out of the file and manually insert it again
14:27:21 GMT <psprint> Anyone familiar with use of SCAN command with hiredis
14:30:05 GMT <Olivius67> badboy_: yes from rdb file. Will do what you suggest, thx.
14:47:42 GMT <badboy_> psprint: what's the problem?
15:19:13 GMT <psprint> badboy_: wondered about nested arrays, but it seems that reply->type will be ARRAY, reply->elements[1]->type will be ARRAY, reply->elements[0] will be STRING
15:21:01 GMT <badboy_> zes
15:21:03 GMT <badboy_> yes
22:08:15 GMT <Antiarc> hey folks, I have a redis 3.0.5 cluster, are there any backwards incompatibilities I need to be aware of to upgrade to 3.2.x?
22:08:26 GMT <Antiarc> Hoping I can just upgrade slaves one at a time, failover master, then upgrade master
