### Apache Hop version? 2.13 ### Java version? Java 1.8.0_401 (Java SE 8) ### Operating system Windows ### What happened? When using the Table Input step, the Preview function hangs indefinitely if the underlying table contains a large volume of data — even when a row limit is set in the "Number of rows to preview" field (e.g., 10 rows). No error is shown; the interface simply freezes on the preview loading screen. Unexpected behavior: Setting preview to 10 rows → hangs on loading. Using a LIMIT clause directly in the SQL query or SELECT COUNT(*) works instantly. It seems Apache Hop is still attempting to analyze or cache a large part of the table before applying the preview limit. Expected behavior: The preview should respect the row limit and return results quickly, even on large tables. Environment: Database: PostgreSQL and Firebird ### Issue Priority Priority: 1 ### Issue Component Component: Hop Gui -- This is an automated message from the Apache Git Service.
