[Swift-user] Concurrent mappers

[Michael Wilde]

Jonathan, the files created by the concurrent mapper default to being 
temporary.

To make them persist after the swift command terminates, add this to 
swift.properties:

file.gc.enabled=false

(This needs to be added to the User Guide. Its desrcibed at the moment 
only in etc/swift.properties):

# Files mapped by the concurrent mapper (i.e. when you don't
# explicitly specify a mapper) are deleted when they are not
# in use any more. This property can be used to prevent
# files mapped by the concurrent mapper from being deleted.
#
# Format:
# file.gc.enabled=(true|false)
#
# Default: true
#

After the run is complete, it looks like those files are not retained, or at least do not appear in the location that I've specified. I see a _concurrent directory but it is empty. If I specify a directory as part of the prefix (e.g., <concurrent_mapper;prefix="out/sim",suffix=".out">;) I see an "out" directory inside the _concurrent directory but that directory is empty.
