The `data`, `delete`, `manifest` and `manifest list` files are encrypted and tamper-proofed before being sent to the storage backend. + +The `metadata.json` file does not contain data or stats, and is therefore not encrypted. Review Comment: Thanks again @singhpk234, can you please clarify a few points 1. Is the following true? - partition summary is not a part of the snapshot summary in the Iceberg spec https://iceberg.apache.org/spec/#optional-snapshot-summary-fields ; but in the implementation, it is added sometimes to the snapshots and can contain data stats. 2. If yes, when the partition summaries are enabled, and when do they have stats? Is any of this under the writing user control? 3. Can you give an example of such a usecase (that writes stats to the metadata.json)? -- This is an automated message from the Apache Git Service.
