Slow snapshots
Creating a snapshot for backup purposes is done by creating a hard link to SSTables. In the
absence of JNA, it is done by using
/bin/ln
by
fork
and
exec
to create a hard link.
This is observably slow with thousands of SSTables. Thus, if you are seeing an abnormally
high snapshot time, check whether you have JNA configured.
