Each stage has different TTL settings and Segment Creation Policies. +Each group of records/metrics can be automatically migrated and stored in different stages according to the configuration. + +## Stages Definition +- **hot**: The default first stage for storing data. The data is the newest and most frequently queried. +- **warm**: Optional, the second stage for storing data. The data is less frequently queried than the hot stage. +- **cold**: Optional, the third stage for storing data. The data is rarely queried and is stored for a long time. Review Comment: ```suggestion - **cold**: Optional, the third stage for storing data. The data is rarely queried and is stored for a long time. The query performance is significantly lower than the hot/warm stages data. ``` -- This is an automated message from the Apache Git Service.
