Question 1: If you can improve the operation of KETTLE by modifying the memory size:
Hello!
Kettle sets the virtual machine memory to solve the Out of Memory method as follows:
1. Open Pentah Kettle spoon.sh, or spoon.bat (through the "edit" state);
2. Modify the following parameters in the file:
REM ****** **************************************************** **********
REM ** Set java runtime options **
REM ** Change 512m to higher values in case you run out of memory **
REM ** or set the PENTAHO_DI_JAVA_OPTIONS environment variable **
REM ** **************************************************** **************
if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xmx512m" "-XX:MaxPermSize=256m"
-Xmx512m is to set the virtual memory 512m. By modifying the -Xmx parameter, the memory size of the Java heap space can be set. For example: -Xmx1024m
