What is the retention requirement for Cortex Data Lake sizing?

The retention requirement for Cortex Data Lake sizing is based on the number of days that logs are retained. This is crucial because it determines how long the data will be available for analysis and compliance purposes. Organizations often have specific needs for log retention based on regulatory requirements or internal policies, so the ability to specify retention in terms of days allows for flexible planning and sizing of the data lake to accommodate those needs.

For example, if an organization requires logs to be kept for 90 days, the data lake must be sized to store that volume of data. This retention period directly influences the storage capacity and the performance of log querying and analysis.

The other choices relate to aspects of the infrastructure or operational parameters but do not define the retention in a manner that influences the capacity planning for Data Lake sizing specifically based on the length of time data must be stored.
