What is event-driven testing?

Basically, an event-driven application architecture is one in which services (aka functions) within an application input data and output data via messages that are stored in a message queue. This differs from a synchronous architecture, in which data is passed straight to a service by making a direct call.

How do you test Kafka events?

The Test Machine

  1. Ensure supporting topics exist.
  2. Start the application under test (“application” here could mean Kafka Streams, Kafka connectors, Samza, etc.)
  3. Send some input events.
  4. Wait until the application has finished processing the test input.
  5. Assert that it looks right.

How do you test Microservices performance?

Load Testing Tools for Microservices

  1. InfluxDB is an open-source application written in the Go language.
  2. Grafana It is an open-source metric visualization and analytics suite.
  3. Amazon CloudWatch is a monitoring service that evaluates resource usage for applications or microservices deployed on AWS.

What is an event in event-driven architecture?

An event-driven architecture uses events to trigger and communicate between decoupled services and is common in modern applications built with microservices. An event is a change in state, or an update, like an item being placed in a shopping cart on an e-commerce website.

How do I know if Kafka is running?

1 Answer

  1. Expose a simple “health check” (or “running yes/no check”) in your Kafka Streams application, e.g. via a REST endpoint (use whatever REST tooling you are familiar with).
  2. The health check can be based on Kafka Streams’ built-in state listener, which you already know about.

What does a load tester do?

Load testing is performed to determine a system’s behavior under both normal and anticipated peak load conditions. It helps to identify the maximum operating capacity of an application as well as any bottlenecks and determine which element is causing degradation.

How can I improve my microservices performance?

Best Practices for Microservice Performance

  1. Table of contents.
  2. Turn CRUD operations into microservices.
  3. Provide batch APIs.
  4. Use asynchronous requests.
  5. Use the shortest route.
  6. Avoid chatter during security enforcement.
  7. Trace microservice requests.

What is event driven architecture example?

An Event-Driven Architecture for data and applications is a modern design approach centered around data that describes “events” (i.e., something that just happened). Examples of events include the taking of a measurement, the pressing of a button, or the swiping of a credit card.

What is event driven architecture EDA and why does it matter?

Event-driven architecture (EDA) is a software design pattern that enables an organization to detect “events” or important business moments (such as a transaction, site visit, shopping cart abandonment, etc) and act on them in real time or near real time.

Does Kafka have a REST API?

The Kafka REST Proxy provides a RESTful interface to a Kafka cluster. It makes it easy to produce and consume messages, view the state of the cluster, and perform administrative actions without using the native Kafka protocol or clients.
