Designing for Low-Latency Reads with Duplicate Covering Indexes
The blog explores how using geographically located duplicate covering indexes in a YugabyteDB database cluster can ensure low-latency reads in multi-region deployments. These indexes allow applications to read data from the same region they are deployed in, optimizing performance and consistency while avoiding stale data. However, this design increases write latency due to the need for cross-region traffic and multiple data copies.
