title: Very Big CSV File - How to Read Only Certain Rows into Data Frame
body: <p>I have a very large csv file that I cannot use pandas read_csv to load to my computer memory.</p>
  
  <p>I look at <code>dask.dataframe as dd</code></p>
  
  <p>I need to use dask to read only certain rows of certain columns from that csv file and store it as a panda dataframe.</p>
  
  <p>For example:</p>
  
  <pre><code>User  ProductA  ProductB
  A     1         2
  B     2         3
  C     3         1
  </code></pre>
  
  <p><strong>How can I only read the row for user C and column ProductA using dask ?</strong></p>
  
  <p>Required output as data frame:</p>
  
  <pre><code>User  ProductA
  C     3
  </code></pre>
