如何使用StackDriver API的v2查询BigQuery用法？

我准备用这些Stackdriver API金跟踪BigQuery的使用情况和存在设置此功能的一个很好的教程在这里.但是,此处的查询使用API 的弃用v1,并且可用文档仍然适用于v1.

在BigQuery控制台中,v2仅提供以下字段:

logName
timestamp
severity
insertId
resource
resource.type
resource.labels
resource.labels.project_id
httpRequest
httpRequest.requestMethod
httpRequest.requestUrl
httpRequest.requestSize
httpRequest.status
httpRequest.responseSize
httpRequest.userAgent
httpRequest.remoteIp
httpRequest.serverIp
httpRequest.referer
httpRequest.cacheHit
httpRequest.cacheValidatedWithOriginServer
httpRequest.latency
httpRequest.cacheLookup
httpRequest.cacheFillBytes
operation
operation.id
operation.producer
operation.first
operation.last
protopayload_google_cloud_audit_auditlog
protopayload_google_cloud_audit_auditlog.serviceName
protopayload_google_cloud_audit_auditlog.methodName
protopayload_google_cloud_audit_auditlog.resourceName
protopayload_google_cloud_audit_auditlog.numResponseItems
protopayload_google_cloud_audit_auditlog.status
protopayload_google_cloud_audit_auditlog.status.code
protopayload_google_cloud_audit_auditlog.status.message
trace
sourceLocation  
sourceLocation.file 
sourceLocation.line 
sourceLocation.function

现在没有totalBilledBytes字段,在示例v1查询中用于计算使用情况.如何使用API​​的v2查询使用成本？
