Logstash 2.2.0 and 2.1.2 released
Blog post from Elastic
Logstash 2.2.0 and 2.1.2 were released as part of an extensive update to the Elastic Stack, featuring significant enhancements to Logstash’s internal architecture, notably with the introduction of the "Next Generation Pipeline" (NG pipeline). This new pipeline processes events in micro-batches, increasing performance by up to 28% compared to the previous version, and changes how the filter and output stages operate by running them in sequence in each worker thread. This version simplifies the management of output performance with automatic scaling and encourages plugin authors to use the multi_receive interface to handle events, which improves efficiency and moves closer to achieving event persistence. The Elasticsearch output bundled with this release has been optimized for the NG pipeline with improved retry handling and new features, such as support for scripts to update documents, aligning with the shift from node to HTTP protocol for easier operational management. Additionally, various bugs have been fixed, enhancing the functionality of file input, Kafka, and HTTP components, demonstrating the continued dedication to refining the user experience and system performance.
