Vector Databases Compared: Evaluating DataStax Astra DB Serverless (Vector) and Pinecone Vector Database

The study found that Astra DB significantly outperformed Pinecone p2x8 in ingesting and indexing data, performing six times faster and with a low relative variance, making the ingest workflow more predictable. Astra DB also showed faster response times during active indexing and produced recall ranging from 90% to 94% versus Pinecone’s recall in the range of 75% to 87%. For larger datasets, Astra DB showed better recall and low variance, demonstrating accuracy and consistency. Finally, our testing and configuration pricing revealed that Pinecone’s TCO was 2.2 to 4.9 times greater than Astra DB, making it significantly more expensive to operate.
