Big Query中的JSON的架构应该是什么？

Question

I have the following JSON and i have to import it to Big Query. What schema should i specify for the below JSON? What should be the field names of the table? I am using BigQuery WebUI.

     {
      "users": {
        "userid1mohan": {
          "password": "123456",
          "username": "mohan"
        },
        "userid2kutubuddin": {
          "password": "234567",
          "username": "kutubuddin"
        },
        "userid3pankaj": {
          "password": "345678",
          "username": "pankaj"
        },
        "userid4vivek": {
          "password": "456789",
          "username": "vivek"
        }
      }
    }

Answer 1

Please note that BigQuery will easily ingest CSVs and newline delimited JSONs, but not a plain JSON file like the one provided in the question.

Find a specification on the newline delimited JSON format here: http://dataprotocols.org/ndjson/

For a use case like this one, the nljson would need to look like:

{"username":"kutubuddin","password":"456789"}
{"username":"pankaj","password":"312231"}
{"username":"vivek","password":"123h1"}

So you'll need to transform the json object you have into multiple json objects, one in each line, before ingesting it into BigQuery.
