Optimizing Lookup transformations

Optimizing Lookup transformations

If the lookup table is on the same database as the source table and caching isn't feasible, join the tables in the source database rather than using a Lookup transformation.
When you use a Lookup transformation, perform the following tasks to increase performance:
  • Cache lookup tables.
  • Optimize the lookup condition.
  • Filter lookup rows.
  • Index the lookup table.
  • Optimize multiple lookups.
