作业图太大，无法提交到Google Cloud Dataflow

Question

我正试图在Dataflow上运行作业，每当我试图将其提交到使用Dataflow Runner运行时，我都会从服务收到以下错误：

{
  "code" : 400,
  "errors" : [ {
    "domain" : "global",
    "message" : "Request payload size exceeds the limit: x bytes.",
    "reason" : "badRequest"
  } ],
  "message" : "Request payload size exceeds the limit: x bytes.",
  "status" : "INVALID_ARGUMENT"
}
Caused by: com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 Bad Request
{
  "code" : 400,
  "errors" : [ {
    "domain" : "global",
    "message" : "(3754670dbaa1cc6b): The job graph is too large. Please try again with a smaller job graph, or split your job into two or more smaller jobs.",
    "reason" : "badRequest",
    "debugInfo" : "detail: \"(3754670dbaa1cc6b): CreateJob fails due to Spanner error: New value exceeds the maximum size limit for this column in this database: Jobs.CloudWorkflowJob, size: 17278017, limit: 10485760.\"\n"
  } ],
  "message" : "(3754670dbaa1cc6b): The job graph is too large. Please try again with a smaller job graph, or split your job into two or more smaller jobs.",
  "status" : "INVALID_ARGUMENT"
}

我如何更改我的工作，使其更小，或增加工作大小限制？
