Fix Nulls in 2 Mins: Cleaner JSON Data with Jolt Code

Simplifying Big Data Processing: A 2-Minute Jolt Code Fix for Cleaner JSON Data

When working with big data streams, null values can hinder efficient and accurate data processing. In this article, we'll explore the benefits of using Jolt code to eliminate these null values, ensuring a smoother data processing experience.

Jolt code is specifically designed for big data streams, and it's surprisingly easy to use. For instance, you can utilize Jolt to remove null values with the following code:

[
  {
    "operation": "default",
    "spec": {
      "address": "",
      "somesensorvalues[]": {
        "*": {
          "sensor1": false
        }
      },
      "startTime": "",
      "onStartTime": "",
      "markId": "",
      "markName": "",
      "stoppedTime": "",
      "startTime2": "",
      "powerSetting": "false",
      "speed": 0,
      "id": 0,
      "city": "",
      "state": ""
    }
  },
  {
    "operation": "shift",
    "spec": {
      "*": "&"
    }
  }
]

To put this concept into perspective, let's consider an example of source data:

{
  "address" : "2000 Electric Avenue",
  "somesensordata" : [ {
    "sensor1" : null
  } ],
  "city" : "hightstown",
  "deviceId" : 5454545,
  "dateTime" : "2017-08-07 14:56:09",
  "id" : 6831491,
  "idle" : false,
  "startTime" : null,
  "onStartTime" : null,
  "markId" : null,
  "markName" : null,
  "zipCode" : "08520"
}

By applying Jolt code to remove null values, you can significantly improve the efficiency and accuracy of your big data processing. For more insights on streamlining big data, check out t8tech.
