Subject [jira] Updated: (CASSANDRA-1791) Return name of snapshot directory after creating it
Date Wed, 12 Jan 2011 00:38:47 GMT


Jonathan Ellis updated CASSANDRA-1791:

    Attachment: 1791-v2.txt

v2 attached w/ some cleanup.

does it make sense to default clearsnapshot to ""?  won't that always fail, since tag can't
be empty on create?  seems like we should reject that and make the tag req'd on clear.

> 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.
