set_peer_exclude_namespaces

Daria Barysheva

Definition

Sets not replicable namespaces for the replication relationship (peer). Remember the following restrictions:

  • The REPLICATE_ALL flag should have the true value in the replication peer configuration (see set_peer_replicate_all).

  • Setting an excluded namespace means that all tables in this namespace are not replicated. If the peer configuration already contains some excluded table (added via set_peer_exclude_tableCFs), then setting its namespace with this command is not allowed.

  • If you need to clear excluded namespaces, run the current command with an empty array as the second input parameter. Do not use the remove_peer_namespaces command.

Usage

set_peer_exclude_namespaces '<peer_id>', <namespaces_array[]>
Arguments
Parameter Description

peer_id

A unique identifier of the replication peer. Should not contain hyphens

namespaces_array

An array of strings specified in the format '<namespace_name>', where <namespace_name> — a namespace name
