So @MrDerecho , are you saying that you are looking for a function that can
remove a `DataFile` entry, and then create a new snapshot with an updated
`ManifestFile`?
Does this illustration capture the problem?
```mermaid
graph TD
subgraph Iceberg Table Metadata
manifest1["ManifestFile"]
snapshot1["Snapshot"]
dataFile1["DataFile A"]
dataFile2["DataFile B"]
parquetFile["Parquet File (s3://bucket/path/to/data.parquet)"]
end
snapshot1 --> manifest1
manifest1 --> dataFile1
manifest1 --> dataFile2
dataFile1 --> parquetFile
dataFile2 --> parquetFile
note1["Note: Both DataFile A and B point to the same Parquet file"]
note1 --- parquetFile
```
Which i think could include situations like this as well:
```mermaid
graph TD
subgraph Iceberg Table Metadata
snapshot1["Snapshot"]
manifest1["ManifestFile A"]
manifest2["ManifestFile B"]
dataFile1["DataFile A (in Manifest A)"]
dataFile2["DataFile B (in Manifest B)"]
parquetFile["Parquet File (s3://bucket/path/to/data.parquet)"]
end
snapshot1 --> manifest1
snapshot1 --> manifest2
manifest1 --> dataFile1
manifest2 --> dataFile2
dataFile1 --> parquetFile
dataFile2 --> parquetFile
note1["Note: Both Manifest Files refer to DataFiles that share the same
physical Parquet file"]
note1 --- parquetFile
```
