Differential Versioning

  • Instead of creating entirely new data packages for each version, implement a differential versioning system. This system would only store the changes made between versions, rather than duplicating all files.
  • Each version would be a set of "deltas" or changes from the previous version. This approach significantly reduces storage requirements and indexing complexity.
