What is "bucket freezing" in Splunk?

Bucket freezing in Splunk refers to the process wherein aged data that is no longer actively being used for searches is moved to frozen storage. This transition happens when data has reached a certain age or has exceeded defined retention policies. When data is frozen, it is typically removed from the searchable index, allowing Splunk to optimize performance by managing space and efficiently handling active data.

The significance of this process lies in its contribution to effective data lifecycle management. After data is frozen, it can still be available for future retrieval if needed, depending on the organization's data retention policies. This helps organizations manage storage costs while ensuring compliance with data governance practices.

Understanding the role of bucket freezing is crucial because it directly impacts how Splunk manages data over time and contributes to efficient search performance while maintaining the necessary historical data for compliance and analysis.
