What is the default maximum number of hot buckets allowed in Splunk?

The default maximum number of hot buckets allowed in Splunk is three. Hot buckets are used for ongoing write operations in Splunk’s indexing process. When data is ingested, it initially goes into hot buckets, where it is still being indexed and is available for searching in real-time. The setting of three hot buckets is designed to balance performance and resource utilization.

Having a greater number of hot buckets can enhance write performance, as it allows for parallelism in data writing; however, too many can also lead to increased resource consumption on the indexer. This leads to considerations for capacity planning and tuning based on the specific requirements of the Splunk deployment.

Understanding this default configuration is crucial for effectively managing data ingestion and search performance in Splunk environments. This knowledge also helps in making informed decisions when adjusting bucket configurations to meet unique data handling demands.
