⌨️ What I did

  • vop create가 오면 usearch 인덱스 객체를 만들고, 인덱스 이름으로 레지스트리(HashMap)에 등록합니다.
  • 이번 PR은 "인덱스 객체를 만들고 이름으로 찾을 수 있게 한다"까지입니다.
    • 추후에 usearch 인덱스 객체를 한번더 감싸 readcount 같은 인덱스 관리를 위한 걸로 한번더 wrapping하게될 예정

메트릭 별칭 제거

protocol PR에 문서에 없는 별칭이 들어가 있었습니다.

이제 문서대로 cos, l2, ip, hamming, tanimoto만 받습니다.
아래 별칭은 CLIENT_ERROR bad command line format으로 거절합니다.

(maxcount None 제거는 추후에 바꿀 예정)

  • 제거한 별칭 : cosine, l2sq, euclidean, dot, jaccard

Summary by CodeRabbit

  • 새 기능
    • 이제 인덱스 생성 요청을 처리하며, 성공하면 CREATED 응답을 반환합니다.
    • 생성 시 메트릭과 양자화 설정을 지정할 수 있습니다.
  • 변경 사항
    • 이미 등록된 이름으로 인덱스를 생성하면 EXISTS 응답을 반환합니다.
    • 메트릭 입력은 cos, l2, ip, hamming, tanimoto를 지원합니다. 기존 별칭(cosine, l2sq, euclidean, dot, jaccard)은 더 이상 허용되지 않습니다.

Walkthrough

생성 요청은 이제 usearch 인덱스를 생성하고 이름으로 등록합니다. ASCII 실행 경로는 성공 시 CREATED, 실패 시 해당 오류를 반환합니다. 생성 설정은 MetricKind와 ScalarKind을 사용하며, metric 별칭 입력은 거부합니다.

Changes

인덱스 생성

Layer / File(s) Summary
생성 설정과 프로토콜 계약
Cargo.toml, src/protocol.rs
usearch 의존성을 추가했습니다. Create의 메트릭과 양자화 타입을 usearch 타입으로 변경하고, metric 별칭을 파싱하지 않도록 했습니다.
인덱스 생성과 이름 등록
src/lib.rs, src/index.rs
index 모듈과 index::create를 추가했습니다. 인덱스를 설정에 따라 생성해 전역 이름 맵에 등록하고, 중복 이름 및 생성·메모리 예약 실패를 오류로 반환합니다.
ASCII 생성 요청 처리
src/ascii.rs
생성 요청을 index::create에 전달합니다. 성공 응답은 CREATED이며, 동일한 이름의 두 번째 요청은 EXISTS를 반환합니다.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Moderate · previous review 1390f

Repeated index creation with different names grows daemon memory without limit, because indexes cannot yet be dropped or expired. Add a cap on registered indexes, or accept the risk explicitly until the drop and expiry paths land. Duplicate-name requests also allocate native resources before being rejected, which is a minor inefficiency.

중복 이름은 네이티브 인덱스를 만들기 전에 거부하세요.

Index::new가 중복 이름 확인보다 먼저 실행됩니다. 이미 등록된 이름의 요청도 스레드별 컨텍스트 할당 후 EXISTS로 끝납니다. 읽기 잠금으로 먼저 확인하면 이 낭비를 피할 수 있습니다. 쓰기 잠금 아래의 재확인은 동시 생성을 막기 위해 유지하세요.

등록된 인덱스의 누적 메모리를 제한하세요.

서로 다른 이름으로 vop create를 반복하면 INDEXES가 usearch::Index를 계속 보존합니다. drop은 현재 NOT_SUPPORTED이고 exptime도 인덱스를 제거하지 않습니다.

usearch 2.26.0의 기본 생성 경로는 unreserved가 아닙니다. 빈 인덱스도 하드웨어 동시성 수만큼 thread 슬롯을 예약하고, 최소한 threads × metric_.bytes_per_vector() 크기의 cast buffer를 할당합니다. 따라서 메모리 사용량은 차원 수와 CPU thread 수에 따라 커질 수 있습니다. 생성 수에는 등록 수나 메모리 상한이 없습니다.

인덱스 제거·만료 경로를 구현하거나, 그 전까지 등록 수와 메모리 사용량에 상한을 두세요.

indexes.insert(name, index)로 등록되는 인덱스의 누적 메모리를 제한하세요. 인덱스를 제거하거나 만료시키는 경로를
구현하거나, 등록 수와 각 인덱스의 메모리 사용량을 고려한 상한을 등록 전에 검증하고 상한 초과 시 새 인덱스 등록을 거부하세요.
