How is data transitioned from the cold state to the frozen stage in Splunk?

Data in Splunk transitions from the cold state to the frozen stage based on its specified age. In Splunk’s data lifecycle management, once data becomes "cold," it is still accessible but is no longer written to frequently, indicating that it has aged. As the data continues to age and hits a defined retention policy, it eventually qualifies for freezing. This is primarily governed by the 'frozenTimePeriodInSecs' setting, which dictates how long data should exist in the cold state before it is transitioned to frozen, effectively purging it from active storage.

The other choices do not directly relate to the transition from cold to frozen. While the maximum number of hot buckets or data size limits may dictate behavior regarding indexing and the management of hot or warm buckets, they do not control the aging process that leads to the freezing of cold data. Freezing of data is also not initiated manually unless a specific command is issued, but that is a less common operation compared to the automatic aging process. Thus, the aging of data is the key factor that dictates its movement to the frozen state.
