Vertica Overview

1. Introduction

Vertica is a high-performance analytical database management system (DBMS) designed to handle large volumes of data. It is optimized for read-intensive operations, making it ideal for data warehouse applications and business intelligence.

2. Architecture

Vertica's architecture is based on a shared-nothing design, which allows for horizontal scaling. Each node in the Vertica cluster is independent and can store a portion of the data.

Important: Vertica uses columnar storage, which means data is stored in columns rather than rows, enhancing query performance for analytical workloads.

Key Components:

Data Nodes
Master Node
Client Drivers
