thanks for the quick replay and the offerred solution. we are running
the debian package version 1.2.0-1.
Is there a way to get a list of keys witch are in this files. To trigger
a read. We have over 25.000.000 Million records in riak an it's would be
grat to receive the richt ones. Not all.
Thanks in advanced.
