Prior to the update, enterprises using DynamoDB typically had to copy data into OpenSearch or another vector database, such as Pinecone and Weaviate, often using DynamoDB Streams or custom pipelines, which meant operating two data layers and managing embedding generation, backfills, retries, schema changes, security policies, and synchronization, Walter noted.
That dependence on two separate data layers, Walter pointed out, added to query latency and increased the risk of the vector index lagging behind the operational record.
Such delays, according to Ashish Chaturvedi, executive research leader at HFS Research, can have real consequences for AI agents: “If an agent is acting on what it retrieves, a synced-five-minutes-ago copy can mean a confident wrong action.”
