Apache Pulsar Performance Testing with NoSQLBench

NoSQLBench Pulsar Driver is an open-source performance testing tool for Apache Pulsar that simulates realistic production workloads. Unlike other tools, it allows users to define workloads in YAML files and supports various types of Pulsar workloads. The driver also enables fine-tuning of behaviors through configuration settings and offers deterministic, realistic, and production-like Pulsar workload simulation. It can detect abnormal message processing errors like message loss, duplication, and out-of-order. NoSQLBench Pulsar Driver is a powerful tool for performance testing, messaging model design, sizing analysis, and cluster deployment evaluation for applications and systems based on Apache Pulsar.
