NAME

Elastic::Model::Alias - Administer aliases in Elasticsearch

VERSION

version 0.52

SYNOPSIS

$alias = $model->namespace('myapp')->alias;
$alias = $model->namespace('myapp')->alias('alias_name');

$alias->to( 'index_1', 'index_2' );
$alias->to( 'index_1' => \%settings, index_2 => \%settings);

$alias->add( 'index_1', 'index_2' );
$alias->add( 'index_1' => \%settings, index_2 => \%settings);

$alias->remove( 'index_1', 'index_2' );

\%indices = $alias->aliased_to;

See also "SYNOPSIS" in Elastic::Model::Role::Index.

DESCRIPTION

Elastic::Model::Alias objects are used to create and administer index aliases in an Elasticsearch cluster.

See Elastic::Model::Role::Index for more about usage. See Elastic::Manual::Scaling for more about how aliases can be used in your application.

METHODS

to()

$alias = $alias->to(@index_names);
$alias = $alias->to(
    index_name => \%alias_settings,
    ...
);

Creates or updates the alias "name" and sets it to point to the listed indices. If it already exists and points to indices not specified in @index_names, then those indices will be removed from the alias.

You can delete an alias completely with:

$alias->to();

Aliases can have filters and routing values associated with an index, for instance:

$alias->to(
    my_index => {
        routing => 'client_one',
        filterb => { client => 'client_one'}
    }
);

See Elastic::Manual::Scaling for more about these options.

add()

$alias = $alias->add(@index_names);
$alias = $alias->add(
    index_name => \%alias_settings,
    ...
);

"add()" works in the same way as "to()" except that indices are only added - existing indices are not removed.

remove()

$alias = $alias->remove(@index_names);

The listed index names are removed from alias "name".

aliased_to()

$indices = $alias->aliased_to();

Returns a hashref of the current settings for an alias, suitable for passing to "to()". The keys are index names, and the values are the alias settings.
