Logstash 8.8.0 Release Notes

› ›

Fix a race condition that prevents Logstash from updating a pipeline’s configuration with in-flight events experiencing connection errors. #14739 This issue primarily manifests following the update of Elasticsearch credentials through Central Management, after credentials expired while events were in-flight. It causes the Elasticsearch Output to get stuck attempting to send events with the expired credentials instead of using the updated ones. To address this problem, Logstash has improved the pipeline shutdown phase functionality to allow an output plugin to request the termination of the in-flight batch of events; hence preventing the need for administrators to manually restart Logstash. Furthermore, when used in combination with a persistent queue to prevent data loss, the batch is eligible for reprocessing on pipeline restart. Plugin developers can now decide whether to make use of such functionality on output plugins. #14940
