Summary: Release v0.2.0 includes various feature additions, bug fixes, and performance improvements.

Possible Solution

Based on the provided information and code snippets, the solution to the issue should address the following:

• Improve error messages related to RDF operations.
• Ensure that RDF datasets can be loaded correctly, including handling relative IRIs against a base.
• Address any bugs, such as the Binder Bug or issues with dropping RDFGraph.
• Update predicate IRIs setting functionality.
• Enhance support for rdf data types.
• Improve CSR update mechanisms, particularly with COPY REL operations.
• Optimize deletion operations within the CSR.
• Integrate S3 extension capabilities if relevant.
• Implement constant compression techniques.
• Apply dynamic rehash strategies, including support for splitting in the hash index builder.
• Integrate the reworked hash index builder with the CSV reader.
• Enhance end-to-end copy performance.
• Scale the hash index to support larger datasets and workloads.
• Update the Kuzu explorer with the latest changes.
• Improve the scanning of data from pandas DataFrames.

Given the code snippets, the following actions are recommended:

• Review and update error messages in src/processor/operator/persistent/copy_rdf.cpp to provide more detailed and helpful feedback to users.
• Ensure that the RDFGraph class in the hypothesized documentation can load various RDF datasets correctly, handling relative IRIs against a base. This may involve updating the load_dataset method.
• Address any known bugs related to RDFGraph operations, which may require examining the src/binder/bind/copy/bind_copy_rdf_graph.cpp file.
• Update the set_predicate_iris method in the RDFGraph class to ensure that predicate IRIs are set correctly.
• Review the COPY REL operation in the CSR class and optimize it for better performance.
• If there are any nested data types issues, they should be fixed. This may involve looking at the tools/nodejs_api/test/test_data_type.js file for tests related to nested data types and ensuring they pass.
• For dynamic rehashing and hash index scaling, review the HashIndexBuilder and HashIndex classes in the hypothesized documentation and ensure they support the necessary features, such as splitting and primitive key data types.
• Integrate the hash index builder with the CSV reader by updating the integrate_with_csv_reader method in the HashIndexBuilder class.
• If there are any updates related to the Kuzu explorer, ensure that the KuzuExplorer class is updated accordingly.
• For scanning from pandas improvements, ensure that the scan_from_pandas function works efficiently with pandas DataFrames.

Code snippets to check

• src/binder/bind/copy/bind_copy_rdf_graph.cpp

  This file is relevant because it includes code related to RDF graph copying, which is mentioned in the issue as 'load various rdf dataset'.

• src/processor/operator/persistent/copy_rdf.cpp

  This file is relevant as it contains the finalize method for the CopyRdf class, which could be related to the 'load various rdf dataset' and 'error message improvement' tasks.

• src/include/common/constants.h

  This file defines constants that may need to be updated or reviewed as part of the 'Dynamic rehash' and 'Constant compression' tasks.

• src/catalog/table_schema.cpp

  This file is relevant because it includes code related to RDF graph schema, which might be involved in the 'RDF documentation' and 'Setting predicate IRIs' tasks.

• tools/nodejs_api/test/test_data_type.js

  This file contains tests for data types in Node.js API, which might be relevant for the 'more rdf data type support' task.
