Policy phases and actionsedit
There are four stages in the index lifecycle, in the order they are executed.
| Name | Description |
|---|---|
| The index is actively being written to |
| The index is generally not being written to, but is still queried |
| The index is no longer being updated and is seldom queried. The information still needs to be searchable, but it’s okay if those queries are slower. |
| The index is no longer needed and can safely be deleted |
Each of these stages is called a "phase". A policy does not need to configure each phase for an index. For example, one policy may define only the hot phase and the delete phase, while another may define all four phases.
