What this means is that because we can choose between immediate and eventual consistency, we end up with a system that has tunable consistency. Tunable Consistency means that you can set the CL for each read and write request. So, Cassandra gives you a lot of control over how consistent your data is. Comments and thoughts welcome.

Data Consistency in Apache Cassandra — Part 3 was originally published in Software Architecture on Medium, where people are continuing the conversation by highlighting and responding to this story. To gain all those benefits, you are trading off immediate consistency for eventual consistency. Comments and thoughts welcome.

Here are five considerations every software architect and developer needs to take into account when setting the architectural foundations for a fast data platform. Are there inherent time relationships in the messages that need to be preserved as they travel across the system? Determine requirements first. At least once?

Data Consistency in Apache Cassandra — Part 2 was originally published in Software Architecture on Medium, where people are continuing the conversation by highlighting and responding to this story. In next part 3 , we will go a bit deeper into each of the above configurations and will understand different consistency levels.

The need to measure outcomes and business value for software development, and the shift from Project to Product , require the deployment of a scalable and turnkey VSM solution. CIO: “I hear that the bottleneck is in our legacy systems, or our needing more developers, or issues with our culture. Me: “So where is your bottleneck?

Over the past few years I have focused much of my learning and work choices around learning about the design of sociotechnical systems?—?how how to design software architectures and organise teams around them. System Role What is the role of a component in the system. I hope you find these variables useful.

There are thousands of ways we can shape the software systems we build and organise our teams around them. Sociotechnical systems are complex systems formed of complex systems. The products themselves are software systems which grow harder and harder to reason about as they scale and age.

Building on the Queue-Based Load Leveling Pattern , the Competing Consumer Pattern enables a system to process multiple messages concurrently to optimize throughput, to improve scalability and availability, and to balance the workload. To handle this fluctuating workload, the system can run multiple instances of the consumer service.

Technology systems are difficult to wrangle. Our systems grow in accidental complexity and complication over time. Architecture begins when someone has a nontrivial problem to be solved. The product management team states what must be done to solve the problem, and the architect describes how to realize that vision in a system.

The applications must be integrated to the surrounding business systems so ideas can be tested and validated in the real world in a controlled manner. Today, a number of cloud-based, auto-scaling systems are easily available, such as AWS Batch. There are countless systems that can perform this task for small DAGs on a single server.
