Speeding up Queries with Materialized Views

Many applications are more read-intensive than write-intensive. Meaning your application performs more reads than writes. However, we often persist data optimized for writes making querying and composing data intensive at runtime. What’s a solution? I will review different ways of creating materialized views and some trade-offs. YouTube Check out my YouTube channel, where I post all kinds of content accompanying my posts, including this video showing everything in this post. Materialized Views If you have a large system decomposed into many different boundaries, you’ll have data spread across many different databases. When you need to perform any query, often for a UI,… Read More »Speeding up Queries with Materialized Views

Change Data Capture + Event-Driven Architecture

Change Data Capture (CDC) is a way to monitor and capture changes in data so other systems can react to those changes or stay up-to-date with the data. It isn’t new, but it’s been gaining popularity around event-driven architecture. Let me explain so you don’t shoot yourself in the foot.

Change Data Capture Change Data Capture (CDC) is a way to monitor and capture changes in the data in your database, often in real-time. Lately, combining CDC tools… Read More »Change Data Capture + Event-Driven Architecture

Untangling the many aspects of EDA

With the popularity of Microservices, Kafka, and Event Sourcing, the term “Event” has become pretty overloaded and has caused much confusion about what EDA (Event-Driven Architecture) is. This confusion has led to conflating different concepts leading to unneeded technical complexity. I will shed some light on different aspects of EDA, such as Event Sourcing, Event-Carried State Transfer, and Events for Workflow. YouTube Check out my YouTube channel, where I post all kinds of content accompanying my posts, including this video showing everything in this post. “Event” If you ask people how they apply event-driven architecture, you’ll likely get many different answers. It… Read More »Untangling the many aspects of EDA
