    <description>Hi
&lt;BR /&gt;The slow performance is because tPivotToColumnsDelimited needs to load 500K first and calculate the number of columns then.
&lt;BR /&gt;Is it possible to split 500k files into several files in terms of your logic?
&lt;BR /&gt;Or I don't think a workaround exists.
&lt;BR /&gt;Regards,

      <title>Pivot Values to Columns</title>
      <link>https://community.qlik.com/t5/Talend-Studio/Pivot-Values-to-Columns/m-p/2283491#M57391</link>
      <description>i have a structure
&lt;BR /&gt;id | name | value
&lt;BR /&gt;1 | name1 | value1
&lt;BR /&gt;1 | name2 | value2
&lt;BR /&gt;2 | name1 | value1
&lt;BR /&gt;2 | name2 | value2
&lt;BR /&gt;and I need it in the form
&lt;BR /&gt;id | name1 | name2
&lt;BR /&gt;1 | value1 | value2
&lt;BR /&gt;2 | value1 | value2
&lt;BR /&gt;the number of name columns to pivot is dynamic.
&lt;BR /&gt;i have tried using the tPivotToColumnsDelimited component. it is way too slow on a large set, approx 300-800 rec / sec. processing 500k rows is rediculous. anyone have an alternative? using multiple splits/denormalizing would be great if possible. I am still trying to figure out the dynamic column routine somehow.
&lt;BR /&gt;thanks.</description>
