### Question
- What do you want to know?
When I read the document and configure the TTL of the data, I found that the
environment variable configuration of recordDataTTL and metricsDataTTL is the
same, I am not sure whether this is appropriate?
```yaml
recordDataTTL: ${SW_CORE_RECORD_DATA_TTL:3} # Unit is day
metricsDataTTL: ${SW_CORE_RECORD_DATA_TTL:7} # Unit is day
```
