Hi there,
I have to download pretty large files (> 200 MB) from a remote server via http
and process them with a very specific library. This library relies on using
files and not streams, so I have a route looking like
from (...)
.toD("${body}")
.to("file:" + tempDirectoryName)
In the body, I had constructed the URI to the file to be downloaded. I quickly
ran into memory leaks, so I changed the code to
from(...=
.toD("${body}")
.streamCaching()
.to("file:" + tempDirectoryName)
This helped with the memory leak because now the data are written twice on my
disk: one to the temporary directory name that I had intended and one in the
java.io.tempdir directory. The documentation on Camel Stream-caching states
"Camel itself will handle deleting the temporary file once the cached stream is
no longer necessary." But I can't see that happen. The large files remain where
they are. Any ideas what went wrong?
Kind regards,
Christian Jacob
