Index Lifecycle Management
Automate the aging of indices through hot, warm, cold, and delete phases with ILM policies to control cost and performance at scale.
Data Gets Old
Time-based data like logs and metrics keeps growing. Recent data is queried constantly; old data rarely. Index Lifecycle Management (ILM) automates moving indices through phases so you spend resources only where they matter.
The Four Phases
ILM defines up to four phases:
- Hot: actively written and queried.
- Warm: no longer written, still queried.
- Cold: rarely queried, kept cheaply.
- Delete: removed.
