[GitHub] [incubator-paimon] hililiwei opened a new issue, #781: [Feature] Refactor the recording method of snapshot linear history
hililiwei opened a new issue, #781:
URL: https://github.com/apache/incubator-paimon/issues/781
### Search before asking
- [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.
### Motivation
Apache Paimon currently uses the file prefix and file system List command to manage the linear history of snapshots, but this method has the following drawbacks:
- It is not friendly with object storage, where operations such as List\Rename are very resource-intensive.
- This method has a single linear relationship, which is not conducive to creating complex relationships, such as create a new branch\tag.
### Solution
Store the file path of the previous Snapshot directly in the Snapshot object.
### Anything else?
