| Problem | Community Solution | | :--- | :--- | | Memory Leaks in long-running jobs | Use the Clean up step at the end of every loop. Set JVM args: -XX:+UseG1GC -XX:+DisableExplicitGC. | | Slow JDBC reads from PostgreSQL | Change the fetch size in the Database connection > Options tab to 5000. Use Stream Lookup instead of Database Join. | | UTF-8 encoding issues in CSV files | Use the Text File Input step's "Encoding" field. Set it to UTF-8 and uncheck "Parse the date leniently". | | Cannot execute transformation on remote Carte server | Ensure the user cluster has read/write permissions in carte-config.xml. Use curl -X PUT to ping the server status. |

Most open-source tools are "code first." PDI is "metadata first." You can store database connections, lookup tables, and variables in the repository. This allows you to build generic jobs that can run in Dev, QA, and Prod just by changing a variable at runtime. pentaho data integration community
