The bucket types (hot, warm, or cold) have the same search performance characteristics within the customer’s environment. This is because the customer’s indexers have a single storage device for all data, which means that there is no difference in the speed or access time of the data stored in different bucket types. Splunk Enterprise stores indexed data in buckets, which are directories containing both the raw data and index files. The bucket types (hot, warm, or cold) indicate the age and status of the data in the buckets, but they do not affect the search performance by themselves. The search performance depends on the underlying storage device and its characteristics, such as I/O throughput, latency, and capacity.
The other options are incorrect because they either do not apply to the customer’s environment or they contain false or misleading information. Option B is incorrect because thawed buckets are not a regular bucket type, but rather a special type of buckets that are restored from frozen or archived data. Thawed buckets do not have any optimized structure that makes them more performant than other bucket types. Option C is incorrect because cold buckets are not miniaturized by removing TSIDX files, which are the index files that enable fast searching of the data. Removing TSIDX files would make the data unsearchable, not faster to search. Option D is incorrect because the customer’s environment does not have a cheaper/slower storage volume for cold buckets, as they have a single storage device for all data. Even if they had a different storage volume for cold buckets, it would not necessarily be slower than SSD, as there are other factors that affect the storage performance, such as RAID configuration, caching, and compression.
