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
OutOfMemoryError
s 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.
