--source-keyspace keyspace_name
(required)-
The source cluster keyspace to replicate.
--source-table source_table_name
(required)-
The source table to replicate.
--source-id id
-
A unique identifier for all data that comes from a particular source node.
--source-id-column source_id
-
The column that identifies the source id in the destination table.
--destination destination
(required)-
The destination where the replication is sent; the user names the destination.
--destination-keyspace keyspace_name
-
The destination keyspace to which the replication is sent.
--destination-table table_name
-
The destination table to which the replication is sent.
--fifo-order
-
First in, first out channel (FIFO) replication order. Default.
--lifo-order
-
Last in, last out (LIFO) channel replication order.
--collection-enabled
(true|false
)-
Whether to enable the source table for replication collection on creation.
--transmission-enabled
(true|false
)-
Whether to replicate data collector for the table to the destination.
--priority channel_priority
-
The order in which the source table log files are transmitted.
Examples
To create a replication source channel:
$ dse advrep channel create --source-keyspace foo --source-table bar --source-id source1 --source-id-column source_id --destination mydest --destination-keyspace foo --destination-table bar --collection-enabled true --priority 1
with a result as seen using dse advrep channel status
:
$ Created channel dc=Cassandra keyspace=foo table=bar to mydest
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.
You can also set the source-id
and source-id-column
differently from the global setting.
