Basic Concepts and Architecture of Cassandra

by Vijay Parthasarathy | November 2013 | Open Source Web Development

This article has been created by Vijay Parthasarathy, the author of Learning Cassandra for Administrators. The Apache Cassandra database is a linearly scalable and highly available distributed data store which doesn't compromise on performance and runs on commodity hardware. Cassandra's support for replicating across multiple datacenters / multiple discrete environments is the best in the industry. Cassandra provides high throughput with low latency without any single point of failure on commodity hardware.

Cassandra was inspired by the two papers published by Google (BigTable) in 2006 and Amazon (Dynamo) in 2007, after which Cassandra added more features. Cassandra is different from most of the NoSQL solutions in a lot of ways: the core assumption of most of the distributed NoSQL solutions is that Mean Time Between Failures (MTBF) of the whole system becomes negligible when the failures of individual nodes are independent, thus resulting in a highly reliable system.

Organizing a Virtual Filesystem

by Sergey Kosarevsky Viktor Latypov | November 2013 | Cookbooks Open Source

This article has written by Sergey Kosarevsky and Viktor Latypov, the authors of the book Android NDK Game Development Cookbook is devoted entirely to the asynchronous file handling, resource proxies, and resource compression. Many programs store their data as a set of files. Loading these files without blocking the whole program is an important issue. Human interface guidelines for all modern operating systems prescript the application developer to avoid any delay, or "freezing", in the program's workflow (known as the Application Not Responding (ANR) error in Android).

In this article we will cover:

  • Abstracting file streams
  • Implementing portable memory-mapped files
  • Implementing file writers
  • Working with in-memory files
  • Implementing mount points
  • Enumerating files in the .zip archives
  • Decompressing files from the .zip archives
  • Loading resources asynchronously
  • Storing application data
