Hello, friend!

The Hadoop big data platform can be regarded as a next-generation data warehousing system. It has the characteristics of modern data warehouses and is widely used by enterprises. Because of the scalability of MPP, the MPP-based data warehousing system is sometimes classified as a big data platform.

However, data warehouses greatly differ from the Hadoop platform in function and user experience in different scenarios. For details, see the following table.

Feature

Hadoop

Data Warehouse

Number of compute nodes

1000s

Max 256

Data volume

Over 10 PB

Max 10 PB

Data type

Relational, semi-relational, unstructured (voice, images, and video)

Relational only

Latency

Medium to high

Low

Application ecosystem

Innovative/AI

Traditional/BI

Application development API

SQL and other programming language APIs, such as MapReduce

Standard database SQL

Scalability

Unlimited, with comprehensive programming APIs

Limited, supported by UDFs

Transaction support

Limited

Comprehensive

Hope this helps!
