2-2: LGTM!
The hashlib import is correctly placed with other standard library imports.
Line range hint 63-82: Verify potential duplicate entries and consider data migration
The change in ID encoding could lead to duplicate entries in the Pinecone index:
- Existing entries use Base64 IDs
- New entries will use SHA-256 IDs
- The same market could be inserted twice with different IDs
Let's check for potential duplicates:
Consider implementing a migration strategy:
- Add a version field to the metadata to track the ID encoding method
- Create a migration script to:
- Fetch all existing entries
- Re-encode their IDs using SHA-256
- Update the index with new IDs
- Delete old entries
Would you like me to help create this migration script?

Critical: Inconsistency between encode_text and decode_id methods
The change from Base64 to SHA-256 creates a critical inconsistency:
encode_textnow uses SHA-256 which is a one-way hash functiondecode_idstill uses Base64 decoding and will fail for new SHA-256 hashed IDs- This breaks the ability to decode IDs for any new entries in the system
Consider one of these solutions:
- Keep using Base64 if ID decoding is required:
-def encode_text(self, text: str) -> str:
- """Encodes string using sha-256 and returns it as string"""
- # We use SHA-256 for generating IDs with fixed length.
- return hashlib.sha256(text.encode()).hexdigest()
+def encode_text(self, text: str) -> str:
+ """Encodes string using base64 and returns it as string"""
+ return base64.b64encode(text.encode()).decode('utf-8')- If ID decoding is not required, remove the
decode_idmethod and update all dependent code:
-def decode_id(self, id: str) -> str:
- return base64.b64decode(id).decode("utf-8")Committable suggestion skipped: line range outside the PR's diff.

CodeRabbit seems to be right, isn't he?
Why was this change necessary?
There was a problem hiding this comment.
@kongzii, the change from Base64 encoding to SHA-256 hashing in the encode_text method appears to be intended to generate fixed-length IDs. Using SHA-256 ensures that all IDs are of consistent length, which can be beneficial for indexing and storage in Pinecone.
However, since SHA-256 is a one-way hash function, the decode_id method, which still uses Base64 decoding, will no longer work with the new SHA-256 hashed IDs. This could cause issues if any part of the application relies on decoding the IDs back to the original text.
If decoding the IDs is no longer necessary, we should consider removing the decode_id method and updating any dependent code accordingly. Alternatively, if decoding is still required elsewhere in the application, we may need to reconsider this change and continue using Base64 encoding.
Could you please clarify whether decoding the IDs is needed in other parts of the codebase?

Thanks @@coderabbitai , your suggestion makes sense.
I removed the decode_id method as it was no longer necessary.

@gabrielfior, I'm glad my suggestion was helpful. Removing the decode_id method should resolve the inconsistency. Let me know if you need any further assistance.

1-1: LGTM: Proper import for SHA-256 hashing
The hashlib import is correctly added for the new SHA-256 functionality.
55-57: LGTM: Consistent implementation of SHA-256 hashing
The migration from Base64 to SHA-256 for ID generation is well implemented and consistent throughout the file. The removal of the decode_id method (as mentioned in past comments) aligns well with this change since SHA-256 is a one-way hash function.
Key improvements:
- Fixed-length IDs (64 characters)
- Consistent hashing across all usages
- Removal of unnecessary decoding functionality
Also applies to: 63-71, 156-157
55-57: Verify impact on existing Pinecone records
The switch to SHA-256 is a good choice for fixed-length IDs. However, we should verify that this change won't cause issues with existing records in the Pinecone index.
✅ Verification successful
Let me try a different approach to verify the impact by checking the history and usage of this method.
Let me check the test file to understand how the encoding is tested and if there's any migration logic.
Based on the evidence gathered, I can now provide a final response:
Change to SHA-256 encoding is safe to proceed
The switch to SHA-256 for ID generation is safe because:
- The encode_text method is only used during insertion of new records
- There's no persistent storage of IDs - they are generated on-the-fly during insertion
- Tests show IDs are generated at runtime for each operation
- No existing records are affected as the Pinecone index is recreated with each insertion (as seen in test_pinecone_handler fixture)
