Safety copy of an Apache Cassandra database
How can I create a safety copy (dump) from Cassandra. Is available any tool like mysqldump
?
Maybe there is a way to make something like an ISO imag开发者_StackOverflow社区e from database?
See http://wiki.apache.org/cassandra/Operations#Backing_up_data
You can use snapshots, or export the data to JSON format.
The COPY
command also could help: Simple data importing and exporting with Cassandra
