Yang Yang commented on CASSANDRA-1872:
--------------------------------------
Thanks Jonathan.
here is the patch to do hardlink before the minor compaction is submitted , in
addSStable(). then we have the hard links in
data_file_location/backup/KS/cf-file-name-same-as-original
we will scrape the dir later to find these files. so the notification mechanism
is not used anymore.
(in fact we were using the hardlink approach before with the JMX notification ,
kind of similar)

> One application of interest is the immediate backup of new SSTables. Relying

> "listeners" to CFS to facilitate this.
