> Key: HBASE-7416

> Project: HBase
> Issue Type: New Feature
> Reporter: Liyin Tang
> Priority: Major
>
> Currently, in tier compaction the aged-based algorithm considers HFile's age
> in disk relative to the current time, thus the tiers are actually shifting
> along the time. In order to best use our prior information about how
> applications consume the data, it needs another feature to perceive the tiers
> relative to a fixed time point.
