DSE Advanced Replication command line tool

The command line tool provides commands and options for configuring and using DSE Advanced Replication.

DSE Advanced Replication commands

These DSE Advanced Replication commands are available:

DSE Advanced Replication command options

Synopsis

dse advrep [--v1] [connection_options] [command] [sub_command] [sub_command_options]

To show the command line help for dse advrep:

dse advrep help

Authentication credentials can be provided in several ways, see Connecting to authentication enabled clusters.

The optional flag, --v1, can be used to access advanced replication commands for DSE 5.0; advanced replication commands changed with DSE 5.1. See DSE 5.0 Advanced Replication documentation for commands compatible with the --v1 flag. An example of using the --v1 flag is:

$ dse advrep --v1 edge conf --edge-id "edge1" --edge-id-col-name "edge_id" --hub-ip-addresses "10.200.182.148"

Client to DSE connection commands

The default port for DSE Advanced Replication is 9042. Connection options are specified as:

dse advrep [connection_options]
Connection options
Connection options Description

--separator field_separator

Specify the field separator if --no-pretty-print is used for printing. Default: comma

--no-pretty-print

If specified, data is printed as a comma delimited list. If not specified, data is printed as tabular output.

-u username

DSE username, or alternatively, DSE_USERNAME environment variable can be used.

--jmx-user

JMX metrics user

--jmx-port

JMX port (default: 7199)

--jmx-pwd

JMX metrics password

-p password

DSE password, or alternatively, DSE_PASSWORD environment variable can be used.

--use-server-config

Read connection configuration from server YAML files (dse.yaml and cassandra.yaml) instead of reading them from configuration files. Use only when the DSE installation against which the command run is a running node.

--cipher-suites ssl_cipher_suites

A comma-separated list of SSL cipher suites for connection to DSE when SSL is enabled. For example, --cipher-suites=c1,c2,c3.

--host address

The DSE host RPC broadcast address. The default value is localhost.

--port port

The DSE native protocol RPC connection port.

--kerberos-enabled true|false

true | false - If true, enable Kerberos for connection to DSE. For example, --kerberos-enabled true.

--keystore-password ssl_keystore_password

Keystore password for connection to DSE when SSL client authentication is enabled.

--keystore-path ssl_keystore_path

Set path to the keystore for connection to DSE when SSL client authentication is enabled.

--keystore-type ssl_keystore_type

Set keystore type for connection to DSE when SSL client authentication is enabled. JKS is the type for keys generated by the Java keytool binary, but other types are possible, depending on user environment.

--truststore-password ssl_truststore_password

Set the truststore password for connection to DSE when SSL is enabled.

--truststore-path ssl_truststore_path

Set path to truststore for connection to DSE when SSL is enabled.

--truststore-type ssl_truststore_type

Set truststore type for connection to DSE when SSL is enabled. JKS is the type for keys generated by the Java keytool binary, but other types are possible, depending on user environment.

--sasl-protocol-name dse_service_principal

The SASL protocol name must match the username of the Kerberos service principal used by the DSE server.

--ssl

Specify whether SSL is enabled for connection to DSE. --ssl-enabled true is the same as --ssl.

--ssl-protocol ssl_protocol

SSL protocol for connection to DSE when SSL is enabled.

-t

Delegation token which can be used to login, or alternatively, DSE_TOKEN environment variable can be used.

Connection options examples:

dse advrep --host ip-10-200-300-138.example.lan --kerberos-enabled=true conf list

and

dse advrep --use-server-config conf list

Printing option example:

dse advrep --no-pretty-print destination list-conf --separator "|"
