B.3.3.4 Miscellaneous Flags

A few additional flags are also available:

-disk
Sets the default storage manager to a disk-based one. This means that if the program needs to store table data in a temporary cache it will use a temporary file on disk rather than doing it in memory. This is therefore a useful flag to specify if you are getting OutOfMemoryErrors reported. Note however that in many cases tpipe's processing is stream-based, so that not much scratch space is required even for processing very large tables.

This is effectively the same as setting the system property -Dstartable.storage=disk.

-help
Prints an informative usage message, as shown in Appendix B.3.2.
-verbose
Causes the program to print more description of what it's doing. This includes a progress line of ASCII-art which indicates how far it's got through reading the initial table.
-debug
Used for debugging purposes. Amongst other things, it causes full stack traces to be printed rather than a less intimidating one-line error message if something goes wrong. If you are reporting an error, please send the output with the -debug flag specified.

In addition the various system properties described in Appendix A can be set on the command line using the usual -D<prop-name>=<value> formulation.
