Maven – Maven in 5 Minutes. Prerequisites You must have an understanding of how to install software on your computer. If you do not know how to do this, please ask someone at your office, school, etc or pay someone to explain this to you. The Maven mailing lists are not the best place to ask for this advice. Installation Maven is a Java tool, so you must have Java installed in order to proceed.

Visual Guide to NoSQL Systems - Nathan Hurst's Blog. There are so many NoSQL systems these days that it's hard to get a quick overview of the major trade-offs involved when evaluating relational and non-relational systems in non-single-server environments. I've developed this visual primer with quite a lot of help (see credits at the end), and it's still a work in progress, so let me know if you see anything misplaced or missing, and I'll fix it. Without further ado, here's what you came here for (and further explanation after the visual). Note: RDBMSs (MySQL, Postgres, etc) are only featured here for comparison purposes. Also, some of these systems can vary their features by configuration (I use the default configuration here, but will try to delve into others later).
As you can see, there are three primary concerns you must balance when choosing a data management system: consistency, availability, and partition tolerance. According to the CAP Theorem, you can only pick two. Self promotion and Credits. 4 Reasons Why Data Engineers Don't Use Cassandra - Open Source. Three years ago, I was stuck trying to get a use case fit into my Oracle database. It was getting expensive fast and I was running out of budget. A friend suggested I try Apache Cassandra for the task and the time series use case was perfect. It's not a perfect database and it was really hard to get my head around the data model and the driver support was scattered. There were a few points where I was ready to just give up and pay Oracle but I stuck with it. Cassandra was the solution that fit my problem, and after a long uphill climb, it worked better than I'd expected.
A few weeks ago, Apache Cassandra passed a significant milestone - It's five years old! For software, five years is a real milestone for maturity. Consistency is flakey If you have been working with relational databases for a while, the term “Eventual Consistency” seems just like crazy talk. Reads are slow Cassandra was optimized from the beginning for fast writes. You have to be a master at tuning the JVM.
