Definition
In RAG and AI agent architectures, ACID compliance ensures that multi-step state updates—such as synchronizing vector embeddings with metadata stores or committing agentic memory—are processed as atomic, consistent, isolated, and durable transactions. While often traded for performance in early vector databases, it is essential for enterprise RAG to prevent state corruption during concurrent document upserts or complex tool-calling sequences.
Distinguish from 'Eventual Consistency' common in high-throughput distributed vector stores.
"A bank vault's dual-key system where a transaction is only recorded if both the teller and the customer complete their actions simultaneously; otherwise, the vault remains unchanged."
