To get a database dump with data from a Cassandra database, you can use the nodetool utility that comes with Apache Cassandra. Here's how you can do it:

  1. Connect to your Cassandra cluster using the cqlsh command-line tool or any other client that allows you to execute CQL commands.
  2. Use the nodetool utility to take a snapshot of your Cassandra database. Run the following command in the terminal:
1
nodetool snapshot -t <snapshot_name> <keyspace_name>


Replace <snapshot_name> with the name you want to give to your snapshot and <keyspace_name> with the name of the keyspace you want to take a snapshot of.

  1. Once the snapshot is complete, navigate to the snapshots directory in your Cassandra data directory. By default, this directory is located at /var/lib/cassandra/data/
  2. Copy the snapshot files to a location of your choice to create a backup of your database dump with data.


By following these steps, you can create a database dump with data from your Cassandra database using the nodetool utility.
