What is Input Parameters vs Variables in SAP HANA about?
1. Input parameters are used at the projection level to filter data before it reaches downstream nodes, improving performance. Variables can only be used at the semantics level and filter data after it reaches semantics. 2. Referential joins assume referential integrity between tables and are more performant than inner joins for star schemas when integrity is maintained. 3. Text joins join a text table containing language keys to master data tables to provide language-specific text descriptions to users.
