Introducing Multiple Pipelines in Logstash

Logstash, a central component for managing data flows between producers and consumers, historically supported only a single pipeline per instance, leading to complex configurations when handling multiple event streams. Users often resorted to conditional logic to separate these streams, resulting in cumbersome and error-prone setups that struggled with issues such as congestion and differing flow requirements. The introduction of the Multiple Pipelines feature in Logstash 6.0 addresses these challenges by allowing a single Logstash instance to manage several distinct pipelines, each defined in a configuration file called `pipelines.yml`. This advancement simplifies configuration management, improves isolation between flows, and supports dynamic reloading of individual pipelines without interrupting others. The feature is designed to enhance user experience by providing flexibility and efficiency, and it is supported by monitoring tools like X-Pack. Users are encouraged to test this feature in its preview release and provide feedback to further improve its functionality.
