Subject [jira] Updated: (CASSANDRA-1791) Return name of snapshot directory after creating it
Date Fri, 10 Dec 2010 04:57:01 GMT


Nick Bailey updated CASSANDRA-1791:

    Attachment: 0001-Require-user-specified-snapshot-names.patch

Require a user specified tag. Nodetool and clustertool will default to a timestamp.  We will
want to indicate that this change can possibly break any automated backup solutions people
have.  If you have a cron job to snapshot and it provides a snapshot name, it will fail after
this change because there will be no timestamp appended and the snapshot will complain the
snapshot already exists.

> When making a snapshot, the new directory is created with a timestamp and, optionally,
a user-supplied tag. For the sake of automated snapshot-creating tools, it would be helpful
to know unequivocally what the new snapshot directory was named (otherwise, the tool must
search for a directory similar what it expects the name to be, which could be both error-prone
and maybe susceptible to attack).
> Recommend making takeSnapshot and takeAllSnapshot return a string, which is the base
component of the new snapshot's directory name.
