Nov 1, 2024This month, I focused on stability and correctness improvements in the AI Vector Search tutorial within oracle-japan/ocitutorials. Key changes include refactoring the doc_chunks creation SQL to leverage the JSON_TABLE output from the embeddings function, ensuring embedding data and vectors are extracted and stored accurately. This reduces data drift, improves maintainability, and reinforces data pipeline reliability for downstream search accuracy.
