Hey @twuebi @zeroshade I’d like to take up implementing Deletion Vectors.
Here’s how I’m thinking of breaking this down :
1. **Puffin file writer/reader** (the manifest file stores the exact byte
offset/length of the bitmap so can directly read that )
2. **DV reader**
2.5 **Positional Delete Manifest builder**
Needed before DV writer to properly create `Positional DeleteFile`
entries as deletion vectors are just content = 1 (POSITION_DELETES) and file
format as PUFFIN . (also thinking of slipping the Iceberg v2 positional delete
Parquet writer here if possible.)
3. **DV writer**: Finally, the logic to write DV
Let me know if this order makes sense or if something should be grouped
differently.
