title: Dynamodb How to perform update in a list element in an item?
body: <p>I am storing data in a list element. That list attribute consists of multiple fields like year and name. Is there any way I can delete only the rows where year is 2018 like in relational databases??</p>
  
  <p>Data is stored in this manner in which ID is primary key and some other fields as password, city etc. Below is how data is stored in quarters.</p>
  
  <pre><code>{
    "q1risk" : "0",
    "q1targets" : [ ]
  }
  UpdateItem succeeded:
  {
    "q2risk" : "100.0",
    "q2targets" : [ {
      "level" : "Basic",
      "year" : "2017",
      "name" : "1",
      "completed" : "0",
      "category" : "US"
    }, {
      "level" : "Basic",
      "year" : "2017",
      "name" : "2",
      "completed" : "0",
      "category" : "US"
    }, {
      "level" : "Basic",
      "year" : "2018",
      "name" : "3",
      "completed" : "0",
