`dse advrep channel truncate`

Truncates a channel to prevent replicating all messages that are currently in the replication log.

A replication channel is a defined channel of change data between source clusters and destination clusters.

This command is supported only on nodes configured for DSE Advanced Replication.

Syntax conventions Description

Syntax conventions	Description
Italic, bold, or `< >`	Syntax diagrams and code samples use one or more of these styles to mark placeholders for variable values. Replace placeholders with a valid option or your own user-defined value. In CQL statements, angle brackets are required to enclose data types in a set, list, map, or tuple. Separate the data types with a comma. For example: `<datatype2` In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and `solrconfig` files, such as `@<xml_entity>='<xml_entity_type>'`.
`[ ]`	Square brackets surround optional command arguments. Do not type the square brackets.
`( )`	Parentheses identify a group to choose from. Do not type the parentheses.
`\|`	A pipe separates alternative elements. Type any one of the elements. Do not type the pipe.
`...`	Indicates that you can repeat the syntax element as often as required.
`'`	Single quotation marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case. + For Search CQL only: Single quotation marks surround an entire XML schema declaration, such as `'<<schema> ... </schema>>'`
`{ }`	Map collection. Curly braces enclose maps (`{ <key_datatype>:<value_datatype> }`) or key value pairs (`{ <key>:<value> }`). A colon separates the key and the value.
`;`	Ends a CQL statement.
`--`	Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options.

In CQL statements, angle brackets are required to enclose data types in a set, list, map, or tuple. Separate the data types with a comma. For example: <datatype2

In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and solrconfig files, such as @<xml_entity>='<xml_entity_type>'.

[ ]

Square brackets surround optional command arguments. Do not type the square brackets.

( )

Parentheses identify a group to choose from. Do not type the parentheses.

|

A pipe separates alternative elements. Type any one of the elements. Do not type the pipe.

...

Indicates that you can repeat the syntax element as often as required.

'

Single quotation marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case. + For Search CQL only: Single quotation marks surround an entire XML schema declaration, such as '<<schema> ... </schema>>'

{ }

Map collection. Curly braces enclose maps ({ <key_datatype>:<value_datatype> }) or key value pairs ({ <key>:<value> }). A colon separates the key and the value.

;

Ends a CQL statement.

--

Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options.

--source-keyspace <keyspace_name>: The source cluster keyspace to replicate.
--source-table <source_table_name>: The source table to replicate.
--destinations <destination> [ , <destination> ]: One or more destinations where the replication is sent.
--data-center-ids <data_center_id> [ , <data_center_id> ]: One or more datacenters for this channel. The given datacenters must already exist.

Examples

Truncate a replication channel to prevent replicating all messages that are currently in the replication log:

dse advrep channel status --source-keyspace foo --source-table bar \
--destinations mydest  --data-center-ids Cassandra

Result

Channel dc=Cassandra keyspace=foo table=bar to mydest was truncated

The source datacenter is the datacenter in which the command is run. The keyspace and table names on the destination can be different than on the source, but in this example they are the same.
