NAME

Search::Elasticsearch::CxnPool::Async::Static - An async CxnPool for connecting to a remote cluster with a static list of nodes.

VERSION

version 8.00

SYNOPSIS

    $e = Search::Elasticsearch::Async->new(
        cxn_pool => 'Async::Static'     # default
        nodes    => [
            'search1:9200',
            'search2:9200'
        ],
    );

DESCRIPTION

The Async::Static connection pool, which is the default, should be used when you don't have direct access to the Elasticsearch cluster, eg when you are accessing the cluster through a proxy. It round-robins through the nodes that you specified, and pings each node before it is used for the first time, to ensure that it is responding.

If any node fails, then all nodes are pinged before the next request to ensure that they are still alive and responding. Failed nodes will be pinged regularly to check if they have recovered.

This class does Search::Elasticsearch::Role::CxnPool::Async::Static and Search::Elasticsearch::Role::Is_Async.

CONFIGURATION

nodes

The list of nodes to use to serve requests. Can accept a single node, multiple nodes, and defaults to localhost:9200 if no nodes are specified. See "node" in Search::Elasticsearch::Role::Cxn for details of the node specification.

METHODS

next_cxn()

    $cxn_pool->next_cxn
             ->then( sub { my $cxn = shift });

Returns the next available live node (in round robin fashion), or throws a NoNodes error if no nodes respond to ping requests.
