Answer / Pinky Mathuria
In Talend, when dealing with large amounts of lookup data, the following techniques can be employed to improve performance:n1. Using In-Memory Cache: By caching the lookup data in memory, subsequent lookups can be performed much faster.n2. Splitting Large Lookup Data: Large lookup files can be split into smaller ones and processed concurrently to reduce the load on the system.n3. Optimizing SQL Queries: If the lookup data is stored in a database, optimizing the SQL queries can significantly improve performance.n4. Using Efficient Data Types: Using efficient data types such as Map or Hash for lookups can provide better performance than other data types.
