Offline first support for long periods

## Summary

Hi, I am looking to implement Amplitude in our fully offline first app that suers can be offline for prolonged periods like weeks. I wanted to check does amplitude offlien support have any limitations for our usecase?

- I know the sdk queues the events offline but is there limitaion of how long the events are stored? like say after N days/hours offline events are discarded?
- Does the ingestion engine have a limit of how far back the analytics events can be backed?
