How Mariadb Achieves Global Scale With Xpand May 2026

: Tables and their associated indexes are broken down into small units called "slices". Unlike other distributed databases that keep indexes local to a node, Xpand distributes indexes independently across the cluster. This prevents "scatter/gather" inefficiencies and allows queries to pinpoint the exact node containing the required data.

Instead of routing all writes to a single primary node, MariaDB Xpand distributes both data and processing power across a cluster of independent nodes. This allows enterprises to handle millions of transactions per second with linear read and write scalability. 🚀 Core Pillars of Xpand's Scalability How MariaDB achieves global scale with Xpand

: Queries are parsed, optimized, and pushed down to be executed concurrently on the specific nodes holding the relevant data slices. : Tables and their associated indexes are broken
