Bio: [D2 CAMPUS FEST mini 최우수상 수상작] Distributed In-memory Key-value Store

Databuter

Databuter는 제 7회 D2 CAMPUS FEST mini의 최우수상 수상작입니다.

Databuter는 분산 인 메모리 키 - 값 스토어 Databute의 서버 구현체입니다.

Databuter의 목표는 메모리에 키 - 값 엔트리를 저장하여, 기존의 데이터베이스 시스템 보다 더 빨리 엔트리를 조회할 수 있도록 하는 것입니다. 또한, 하나 이상의 Databuter 노드가 클러스터를 형성한 뒤 엔트리를 분산시켜 저장하여 용량 및 처리량을 확장하거나, 축소할 수 있도록 하는 것입니다.

사용자는 엔트리를 조회 (GET), 저장 (SET, UPDATE) 및 삭제 (DELETE) 하거나 유효 기간을 설정 (EXPIRE) 할 수 있습니다. 엔트리는 숫자 (Integer, Long), 문자열 (String), 리스트 (List), 셋 (Set) 및 딕셔너리 (Map) 타입을 지원합니다.

엔트리들은 버킷이라 하는 논리적 엔트리 블록에 저장됩니다. Databuter에는 다수의 논리적 버킷이 존재하며, 키를 총 버킷 수에 대해 일관적 해싱을 취한 값과 같은 인자를 가지는 버킷에 엔트리를 저장합니다.

버킷들은 Databuter 클러스터의 노드들이 유지합니다. 한 버킷은 서로 다른 두 노드가 똑같이 유지하고 있어 한 노드에 장애가 발생하더라도 즉시 극복할 수 있습니다.
