Curator is a Python-based tool designed to manage Elasticsearch time-series indices, offering operations such as deleting indices based on age or space consumption, closing indices to free resources, disabling bloom filters in older indices, and optimizing indices through Lucene's forceMerge. Initially developed as a simple script to automate the cleanup of old indices in an ELK stack, Curator has evolved into a comprehensive solution with community contributions that enhance its functionality. The tool allows users to set retention policies by specifying conditions under which indices should be deleted, closed, or optimized, ensuring efficient resource management across Elasticsearch clusters. Curator's operations are executed in a specific order to prevent conflicts, and it supports a range of configurations, including prefix filtering and timeout adjustments, making it suitable for varied cluster sizes and use cases. The tool is available for installation via Git, and future updates aim to make it pip-installable, encouraging wider adoption and community involvement in its ongoing development.
