Introduction Whether you’re integrating multiple microservices, looking to improve app reliability, or building a new streaming app, you might need a message queue (MQ) or message broker platform. These types of software pass messages from producing apps or services to consuming apps or services. Two of the most popular platforms for handling messages are Apache...

Apache Kafka is a distributed streaming platform that offers four key APIs: the Producer API, Consumer API, Streams API, and Connector API with features such as redundant storage of massive data volumes and a message bus capable of throughput reaching millions of messages each second. These capabilities and more make Kafka a solution that’s tailor-made...

If you’re in database administration, chances are you’ve faced an age-old question: is it better to become slightly proficient in lots of different database tools, or become very proficient in one tool that can do a bit of everything reasonably well?  I have been a software engineer for over 35 years, and have been privileged...

This blog provides an overview of the two fundamental concepts in Apache Kafka: Topics and Partitions. While developing and scaling our Anomalia Machina application we have discovered that distributed applications using Apache Kafka and Cassandra clusters require careful tuning to achieve close to linear scalability, and critical variables included the number of Apache Kafka topics and partitions. In this blog, we test that theory and answer questions like “What impact does increasing partitions have on throughput?” and “Is there an optimal number of partitions for a cluster to maximize write throughput?” And more!

How do you use PostgreSQL from Java? With JDBC! (Java Database Connectivity). There’s a PostgreSQL JDBC Driver (PgJDBC for short) which allows Java programs to connect using standard, database independent, Java code. It’s an open source Pure Java (Type 4, which talks native PostgreSQL protocol) driver and is well documented.

PostgreSQL is a powerful and versatile database management system if you’re considering migrating from Oracle to PostgreSQL.
