NAME

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

VERSION

       version 8.00

SYNOPSIS

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

DESCRIPTION

       The 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::Static and
       Search::Elasticsearch::Role::Is_Sync.

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 = $cxn_pool->next_cxn

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