옵션:

-project string
    project ID, if unset uses gcloud configured project
-instance string
    Cloud Bigtable instance
-creds string
    if set, use application credentials in this file

알파 기능은 현재 대다수 Cloud Bigtable 고객들이 사용할 수 없습니다. 이 기능은 이전 버전과 호환되지 않는 방식으로 변경될 수 있으며, 프로덕션용으로 권장되지 않습니다. 여기에는 어떠한 SLA 또는 지원 중단 정책도 적용되지 않습니다.

편의를 위해 -project, -instance, -creds, -admin-endpoint, -data-endpoint 플래그의 값을 ~/.cbtrc에 다음 형식으로 지정할 수 있습니다.

project = my-project-123
instance = my-instance
creds = path-to-account-key.json
admin-endpoint = hostname:port
data-endpoint = hostname:port

모든 값은 선택사항이며 플래그에 의해 재정의됩니다.
