1009-1043: Review ofDatasetCoreAndReadableStreamclass:The modifications to integrate
indexMatchinto theDatasetCoreAndReadableStreamclass are well-implemented. The changes are aligned with the PR's objectives to optimize the matching process. Ensure comprehensive testing, especially for edge cases and large datasets, to validate the performance improvements.Consider adding unit tests to cover edge cases and large datasets to ensure the performance improvements are as expected.
Verification successful
Tests for
DatasetCoreAndReadableStreamare present: The./test/N3Store-test.jsfile contains tests for theDatasetCoreAndReadableStreamclass, which likely cover the integration ofindexMatch. Ensure these tests are comprehensive and consider adding specific tests forindexMatchif needed.

We could optimise slightly further by using the same technique as #readQuads to determine which index to match over first as this will be more efficient for identifying if there are no matches. But it would be sufficient to leave that work for a follow up PR.

1053-1087: Approve modifications inDatasetCoreAndReadableStream.The modifications in the
DatasetCoreAndReadableStreamclass effectively incorporate the newindexMatchfunction to enhance dataset processing. The translation of IRIs into internal numeric IDs and the subsequent use ofindexMatchare well-implemented. Consider further optimizations in future updates, as suggested in previous comments, to improve efficiency further.

1037-1052: Enhance robustness ofindexMatchfunction.The
indexMatchfunction introduces a recursive approach to optimize matching over indices. While the implementation appears efficient for the intended use case, consider adding error handling for unexpected inputs or data types to enhance robustness. Additionally, verify that this function integrates seamlessly with other parts of the system, especially where it's used in theDatasetCoreAndReadableStreamclass.Run the following script to verify the function usage:
Verification successful
Confirm integration and enhance error handling for
indexMatchfunction.The
indexMatchfunction is correctly integrated withinsrc/N3Store.js, with multiple calls using different identifiers. To further improve the function's robustness, consider adding error handling for unexpected inputs or data types. This will ensure the function handles edge cases gracefully and maintains system stability.
