What is the default maximum number of warm buckets in Splunk?

The default maximum number of warm buckets in Splunk is set to 300. In Splunk, data is stored in different types of buckets as it ages through the indexing life cycle. Warm buckets contain data that has been indexed, but is still being actively queried. The number of warm buckets impacts performance; having too few can result in slower searches, as Splunk may have to roll some warm data to cold storage more quickly than desired.

Setting the limit to 300 allows for a substantial amount of warm data to be retained, facilitating enhanced search performance and query execution. This limit can be adjusted based on the specific needs of the deployment and the available storage, but the default helps ensure a balance between performance and resource management for most environments.

The other options suggest lower limits, which may not provide sufficient warm bucket retention for larger datasets or more intensive querying scenarios typical in many Splunk use cases.
