title: Single Lookup Table Talend in Multiple tmaps
body: <p>I am using Talend to do some ETL on some tables from my Database.</p>
  
  <p>I need to do the same tMap operation between the same tables for 3 times, but on different fields.</p>
  
  <p>Since the lookup table is big (100 Milion records), I am wondering if there is some way to load it just once and use the same lookup table for the 3 different tMap components.</p>
  
  <p>Thanks.</p>
