00:01 The first record of what you might consider modern day NoSQL, 00:05 there were some older versions much, much older 00:08 about object databases that don't really carry on through today; 00:12 but what we think of when we talk about NoSQL today 00:15 really started back 2009 in San Francisco. 00:18 So this guy Johan Oskarsson, who at the time was working at last.fm 00:23 was getting together like a big data/ scaling databases 00:27 type of meetup in San Francisco, and the idea was 00:31 we're going to talk about open source databases, 00:34 distributed databases, that is databases that are easily horizontally scalable, 00:39 and that might not be traditionally relational. 00:42 This description here on the right actually comes from Wikipedia, 00:46 the name itself, the actual NoSQL, the word, 00:50 I don't believe it's here, but it was in a previous accounting, it's not in Wikipedia, 00:55 which if I could find the reference, I should go back and edit it, 00:59 is there's another guy named Eric Evans 01:02 who was attending this meeting as well 01:05 and Johan said hey what are we going to call this meeting 01:07 like we do have a name for these types of groups, 01:09 this type of thing that we're doing, and let's try to get something short, 01:12 like say a hashtag that we can use on Twitter to talk about it; 01:16 So Eric Evans said how about #NoSQL, right, 01:19 and that is the origin of the modern day term. 01:22 And the idea was, it was meant to describe this group of people 01:26 mostly running web apps with lots of data, 01:29 with high performance implications, or requirements, 01:32 getting together to talk about how can we give up 01:34 some of the features of relational databases to enable other types of things, 01:39 so maybe we'll give up atomicity, the acid properties, 01:43 maybe we'll give up joins, maybe we'll give up transactions, things like that, 01:48 and if we do that, how do we maybe structure our data differently, 01:51 how do we structure our databases differently, 01:54 to be better at basically being cluster friendly. 01:57 Alright, so to me, this is the idea of what a NoSQL database is, 02:02 it's a database that gives up some of the relational 02:05 database features or requirements or properties, 02:08 so that it is more cluster friendly, it is more friendly to scaling 02:13 and sharding and things like that.
