Warm buckets in Splunk indexes are named by:

Warm buckets in Splunk indexes are named by the timestamps of the first and last event contained within the bucket. This naming convention allows for efficient data management and retrieval, as the timestamps provide quick insight into the contents of the bucket.

The bucket's name typically reflects the time range of the events it holds. This is particularly important for Splunk's internal indexing process, where it needs to quickly locate and process events within specific time frames. By naming buckets based on their contained event timestamps, Splunk simplifies the process of identifying the relevant data that users may want to search, analyze, or archive.

This method enhances the performance of searches as it enables Splunk to quickly assess which buckets need to be scanned based on the search time range specified by the user, optimizing resource utilization and improving overall query response times.
