NAME

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

VERSION

       version 5.01

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.
