In a GBase database , performance and correctness are built on two equally important pillars: A distributed MPP architecture for scalable query execution Precise SQL functions for deterministic data processing This article combines both perspectives using: GBase distributed architecture concepts The TRUNCATE function for numeric precision control 🚀 1. GBase Distributed Architecture Overview GBase is designed as a Massively Parallel Processing (MPP) distributed database system . 🧠 Shared-Nothing Design Each node in the cluster: Stores its own data Executes queries independently Communicates through a coordinator layer Coordinator Node | +-----+-----+-----+ | Node A | Node B | Node C | +--------+--------+--------+ Parallel execution layer Enter fullscreen mode Exit fullscreen mode ` ⚙️ Parallel Query Execution When you run a SQL query: It is split into multiple tasks Each node processes part of the data Results are merged at the end 👉 This enables horizontal scalability.…
