Unloading data without a configuration file

Unload database rows with a dsbulk unload command to CSV/JSON files.

Use the dsbulk unload command to unload database table rows to a CSV or JSON file.

To unload data from a cloud-based DataStax Astra database, specify the path to the secure connect bundle ZIP file. It contains the security certificates and credentials for your database. Also specify the username and password entered when creating the database. For information about downloading the secure connect bundle ZIP via the Astra console, in advance of entering the dsbulk command, refer to Obtain database credentials.

Unload data from a database to a CSV or JSON file

Specify the database’s keyspace ks1 and table table1 from which to unload the data to a CSV/JSON file. Examples:

DataStax Astra databases

dsbulk unload -url myData.csv -k ks1 -t table1 \
-b "path/to/secure-connect-database_name.zip" -u database_user -p database_password

DSE / Open source Apache Cassandra® databases

dsbulk unload -url myData.csv -k ks1 -t table1

The url value can designate a path on the local filesystem or a valid URL.

DSE databases
