Red Hat Summit289.11. Salesforce Composite API를 사용하여 여러 요청을 일괄 처리로 제출
Composite API 배치 작업 (composite-batch)을 사용하면 배치에 여러 요청을 누적 한 다음 한 번에 제출하여 여러 개별 요청의 왕복 비용을 절약 할 수 있습니다. 그런 다음 각 응답은 순서가 보존된 응답 목록으로 수신되므로 n번째 요청 응답이 응답의 n번째 위치에 있습니다.
참고
결과는 API마다 다를 수 있으므로 요청 결과가 java.lang.Object 로 제공됩니다. 대부분의 경우 결과는 문자열 키와 값이 있는 java.util.Map 또는 기타 java.util.Map 값이 값으로 지정됩니다. JSON 형식으로 이루어진 요청은 일부 유형 정보(예: 문자열과 숫자 값이 무엇인지 알 수 있음)를 보유하므로 일반적으로 보다 형식 친화적이 됩니다. 응답은 XML과 JSON마다 다르며, 이는 Salesforce API의 응답이 다르기 때문입니다. 따라서 응답 처리 코드를 변경하지 않고 형식 간에 전환해야 합니다.
예를 들어 다음을 살펴보겠습니다.
