Redis 2.8 hit release candidate 2 status this week with some of the major bugs finally getting fixed. The new release should be a welcome change given Redis' recent, and very public, incident with Twilio's billing system.
If you've tried Riak and didn't like it, or you're about to start using it, you'll want to take a look at this video to see if you were using the best practices when working with this database.
J Brisbin's work with NoSQL datastores over the last couple of years has given me some insight into the direction applications will inevitably take as NoSQL becomes the dominant data storage and retrieval method—at least for web and cloud-based applications.
A relatively new NoSQL data store on the scene is Aerospike. They're focused on pushing the limits of SSD/Flash in-memory data processing and providing "Storm speed" (perhaps he's referring to Twitter Storm?) which is about 10 million messages a second.
This article will show you how core MongoDB operations are made using the MongoDB Java Driver version 2.11.1.
Although it's not yet in a code release, Cloudant and the rest of the Apache CouchDB community has finally finished the merging of BigCouch, a HA, fault-tolerant, clustered version of CouchDB, with the primary CouchDB Apache project. The code is now in the testing phase, which you can help with.
Over the past few years I’ve seen the emergence of polyglot persistence i.e. using different data storage technologies for different data and in most situations we work that out up front. The main down side to this approach is that we now have to keep two data sources in sync but it’s interesting to think about whether this trade off is worthwhile...
Here's a real quick video of the war between SQL and NoSQL methodologies.
I've recently returned from a rather brilliant Couchbase trip to Israel. My colleague Tug Grall and I lead the Couchbase Developer Day held at the LivePerson offices . . .
As mentioned, the data in LMDB is actually stored in page. And I am currently tracking through the process in which we add a new item to the database.
Graph ranking algorithms are all about mapping a complex graphical structure to a numeric vector. For a given algorithm, a single numeric value in the resultant vector corresponds . . .
Here's a discussion of how to manage large numbers of clusters using Chef roles, as well as how to automatically snapshot RAID arrays.
We are happy to announce that we have updated our CUBRID PHP and PDO drivers to roll out loads of improvements and bug fixes.
More than 110 million songs, albums and radio stations have been played 40 billion times through apps integrated with Facebook’s Open Graph.
This lecture from 2010 was presented by Jon Kleinberg of Cornell University. He focuses his discussion of cascading behavior on large social networks by . . .
Here's a 90-minute presentation from SeaJUG 2013. It focuses on a couple popular NoSQL solutions.
The following 1:22 lecture was originally presented by Professor Steven Skiena at the Hong Kong University of Science and Technology.
If I should have made some safe bets on the near future, I would choose two: Hadoop and MongoDB.
Okay, I know that I have been critical about the LMDB codebase so far. But one thing that I really want to point out for it is that it was pretty easy to actually get things working on Windows.
Here's a 1-hour webinar on developing apps with Couchbase using indexes and queries. It was presented by Chris Anderson, chief architect at Couchbase.
I just past my second year anniversary at Health Market Science (HMS), and we've been working with Cassandra for almost the entirety of my career here.
MongoDB is an open source document-oriented NoSQL database system which stores data as JSON-like documents with dynamic schemas.
The NoSQL moniker that was coined circa 2009 marked a move from the “traditional” relational model . . .
So, our managed implementation of leveldb is just about ready to go out and socialize. Note that those are just for a relatively short duration, but they give us good indicator of where we are.
Here's a 38-minute presentation by Hannu Kosing called "PostSQL - Using PostgreSQL as a Better NoSQL"
