8.2 API

type Client interface {
  BuildIndex(req BuildIndexRequest) (BuildIndexResponse, error)
	DescribeIndex(indexID UniqueID) (IndexDescription, error)
	GetIndexFilePaths(indexID UniqueID) (IndexFilePaths, error)
}

• BuildIndex

type BuildIndexRequest struct {
  DataPaths []string
  TypeParams map[string]string
  IndexParams map[string]string
}

type BuildIndexResponse struct {
  IndexID UniqueID
}

• DescribeIndex

enum IndexStatus {
    NONE = 0;
    UNISSUED = 1;

	Status            IndexStatus
	EnqueueTime       time.Time
	ScheduleTime      time.Time
	BuildCompleteTime time.Time
}

• GetIndexFilePaths

type IndexFilePaths struct {
  FilePaths []string
}
