A rewrite of our internal event queue reduces memory requirements for Elastic Agent and Beats. Learn what's changed and how we simplified queue configuration while improving efficiency.

In this blog, learn about the improvements Elastic's Engineering team made to Filebeat memory allocation by removing a logger.
