Understanding Consistency Level in the Milvus Vector Database

This post explains the concept of data consistency in distributed systems and details the four consistency levels supported by Milvus: Strong, Bounded Staleness, Session, and Eventual. It provides use cases for each level and explains how Milvus 2.0's pub-sub architecture enables these tunable levels, contrasting it with Milvus 1.0's single consistency model. The default consistency level is Bounded Staleness.
