[nodejs] Re: Mongo vs. Couch vs. LevelDB ?
MongoDB similar to traditional RDBMS in terms that it's also an universal database applicable to lots of use cases. CouchDB has some unique features, but, it's a specialised database, it may be a good fit for some special use cases, but it's not universal DB, and it's not a good fit for general web app. LevelDB - also specialised and high performant low-level DB, not for general usage.

[nodejs] Re: Mongo vs. Couch vs. LevelDB ?
Hi, each option in the database space is good at different things and have very different usage profiles. The most important question you have to answer before you even think of which DB system to use or whether you even want to use one at all is: What is my data and access profile. For example: * If you never search for data, because you always have a unique identifier (primary key), then maybe you don't need a DB system, but are better off with a Key Value store. * If you never modify data once it has been stored, but simply write once read often, then you have a different need than if you modify your data. (Example: CouchDB gives you strong version enforcement, which you don't need in that case then at the cost of speed and complexity). * How much data are you expecting? Does it even need to be persisted at all? For example if you are only doing session storage, you might be better of just doing a memcached cluster, because if you calculate your data-size, you might be able to handle multiple million users with a few gigs of ram. So the question you have asked is like: I want to move an object, what kind of vehicle should I use Well first you need to think about: What kind of object? Over what kind of terrain? Across Oceans? Off planet? At what speed? … So before you consider what DB to use, first consider your data, then your access patterns, then research the options, and then decide ;) On Wednesday, August 28, 2013 3:35:40 PM UTC+2, Dylan Hassinger wrote: Hi everybody - I am a Node newb building my first app, and trying to figure out which database system to use.

Re: [nodejs] Re: Mongo vs. Couch vs. LevelDB ?
When picking a database, I think it's a bad idea to start by looking at all the databases available to you and comparing their features. That's like comparing all the vehicles available to you for a trap, picking a supersonic jet because of its speed, when all you needed was a bike to cycle 5 minutes down the road. All these databases, key-value stores and search engines are built to solve different problems, and without a problem to solve you can't make an informed decision. Working from the problem to a tools that can fix it is the only way to find the right data store. Here's some examples... You're building a javascript-heavy website that needs to work offline and on mobile. This problem suggests that you need the following attributes: - good syncing conflict resolution support, because changes can be made offline; - if possible, a client-side version so that you can use the same data storage API whether online or offline; - real-time event support, so that you can, for example, show notification to your users when another user makes a change to some data. What might you pick in this scenario? CouchDB is the obvious choice, as at its core it's about syncing and replication, and you can transparently support offline usage with the client-side implementation, PouchDB. You're building a web application where user's interactions are minimal but you serve alot of data, and the data you provide has a clear hierarchy: This suggests: - good support for relations between data, to allow you to turn raw data into data structures on the database side - transaction support, where you can batch together a set of operations to make sure you can rollback if something goes wrong - redundancy, where every write you make can also be made in other places so that, if you master database falls over, you can quickly restore access In this case, you could pick something like PostgreSQL or MySQL (yep, still a good option). Mongo also wouldn't be a bad option, although its (lack of) transaction support has had me quite frustrated recently. To quickly cover some other things you mention: ElasticSearch isn't a database as such – it's an engine for searching your data. If you need to provide search over a ton of data, take a look at it. MongoDB is a document storage engine, and is generally useful, reliable and easy to set up. Redis, LevelDB and other key-value data stores do not offer, natively, support for storing and manipulating data structures because they are just key and value stores. But, as Mikeal said, there's a community around Level (and probably Redis) that's adding these things on top – and in that sense you can 'build your own database'. I don't know anything about RethinkDB - at a cursory glance, it doesn't look like they've rethought much, and it's a young platform so don't expect every problem you come up with to be Googleable. You only get that with mature systems like MySQL, Postgres - but Mongo and Couch are catching up in this area. Both have active and helpful communities, like Node does. On the hosted/self-hosted question – I personally go for hosted databases where the problem suggests it. I'm not an operations guy and I don't know about database system administration. I'm a developer, and I'm concerned with the application logic – keeping a database running, and running fast, is just a distraction. However, if you're working in a team and have servers ( ops people) available, there are good reasons to go for a self-hosted option. As you can tell, there's a lot to picking a data store – but I think one thing's for sure: you have to base a decision on your particular problem.

[nodejs] Re: Mongo vs. Couch vs. LevelDB ?
LevelDB it's not really a dbms, but a library for storing key-value pairs, so there there is no such thing as hosted LevelDB (it's like hosted sqlite, makes no sense). As for Mongo and Couch, I advise you to stick with Mongo unless you no that Couch fits your need. Mongo is muсh more general-purpose solution, like rdbms. You can play with Couch at iriscouch.com or cloudant.com (it's a sort of Couch on steroids option) and see what it is capable off. -- -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups nodejs group.

You might also want to look at GT.M or GlobalsDB - see EWD Lite, which projects them as native JSON databases: http://gradvs1.mgateway.com/download/EWDLite.pdf Rob On Wednesday, 28 August 2013 14:35:40 UTC+1, Dylan Hassinger wrote: Hi everybody - I am a Node newb building my first app, and trying to figure out which database system to use.

Personally, I'd probably opt for couch. It has a nice restful interface that you can interact with.

Re: [nodejs] Re: Mongo vs. Couch vs. LevelDB ?
Thanks for the great thoughts everybody. I had tried to look this stuff up prior to posting, but figured my research would be incomplete without testing the waters here :) also I lot of the blog posts went over my head, this thread was very helpful. I have also been recommended RethinkDB and ElasticSearch. Anybody have opinions on those, or thoughts on how they compare to the others? Thanks again!!

Re: [nodejs] Re: Mongo vs. Couch vs. LevelDB ?
I would phrase this differently. As you write your own database using node.js and LevelDB you can host it pretty much anywhere that you can run a node.js program. Its deployment and management is identical to how you manage your node.js application. This means that you avoid most of the pain that goes with running infrastructure, like traditional databases, and it means you don't really need/want specialized database hosting.
