AWS DynamoDB Local 설치

Overview

이전에 AWS DynamoDB에 대해서 알아보았다.

이번에는 Local Cluster에 DB로 설치하는 방법에 대해서 알아본다.

DynamoDB의 개념에 대해서 알아보고 싶다면 아래의 글을 참고하길 바란다.

DynamoDB 설치

DynamoDB는 In-Memory(Stateless) 방식과 Data Storage(Stateful) 방식으로 설치할 수 있다.

 

DynamoDB Local 이미지의 Docker hub 주소는 아래와 같다.

• https://hub.docker.com/r/amazon/dynamodb-local/tags

 

아래의 방식으로 간단하게 설치 가능하다.

 

 

In-Memory 및 Data Storage 방법 간의 차이점

Feature	In-Memory Method	Data Storage Method
Data Persistence	DynamoDB Local이 중지되면 데이터가 손실된다.	데이터는 디스크에 저장되어 지속적으로 유지된다.
Configuration	`-dbPath` 매개변수가 필요없다.	`-dbPath` 매개변수가 필요하다.
Performance	디스크 I/O가 없으므로 더 빠르다.	디스크 쓰기로 인해 약간 느리다.
Use Case	일시적 또는 임시적 테스트.	지속적인 데이터로 테스트
