Consistency The topic and concept of consistency is very important when you work with a distributed database like Cassandra. When you’re working with a database which runs on only one server, consistency is a non-issue. Comments and thoughts welcome.

The backlash against the backlash against Open Source : Over the past decade, a number of corporate software projects have changed from an open source license, such as Apache, to one of a number of “business source” licenses. These licenses vary, but typically restrict users from competing with the project’s vendor.

I spend a large amount of time translating software requirements into schema and queries. Every time we interact with software that displays a table, we can expect the columns to be sortable like this: Sort-By-Colunn is a great pattern when all the data can fit in the browser.

I feel there’s something missing, an operating system, database, architecture and language combination that assumes that terabytes of main memory, GPUs with their own memory, and 100’s of Gbits of network are the baseline and makes it easier to leverage them together to build things that haven’t been seen before. primarily virtual?—?and

Every few seconds, the application servers collect batches of snapshots and write them to the database where they can be queried by dispatchers managing the fleet. Using a database, dispatchers can query raw telemetry to determine the information they need to manage the fleet in real time. Solution: Real-Time Digital Twins.

To gain all those benefits, you are trading off immediate consistency for eventual consistency. Comments and thoughts welcome.

Google was among the pioneers that created “web scale” architectures to analyze the massive data sets that resulted from “crawling” the web that gave birth to Apache Hadoop, MapReduce, and NoSQL databases. We usually relate SQL to querying tables in relational databases. Determine requirements first. Leverage your SQL knowledge.

One of the biggest time costs in software development is understanding how a system works. As we continuously develop software systems, the complexity slowly increases and we don’t fully realise it. I believe that self-documenting architecture would dramatically reduce one of the big costs in software development.

You need an “abtest” database service. In a small system this may be a table in a central relational database, but it’s best setup as a NoSQL data source using something like Amazon DynamoDB or Apache Cassandra, with a caching client library or at large scale a microservice data access layer.

The microservices era has been good for software architecture. I remember when the idea of multiple databases was punishable by death. A domain service builds on the basic definition of a microservice: it’s a loosely-coupled, independently deployable element of software architecture which is owned by a single team.

These trade-offs have even impacted the way the lowest level building blocks in our computer architectures have been designed. Modern CPUs strongly favor lower latency of operations with clock cycles in the nanoseconds and we have built general purpose software architectures that can exploit these low latencies very well.Â

In software, reacting to unforeseen circumstances in real-time is not possible. The gap between defining business requirements and translating them into software needs to be minimised in order to prevent this category of problems. In the software system, we need to decide the business transaction boundaries aka DDD Aggregates.
