NAME

       Search::Elasticsearch::CxnPool::Static::NoPing - A CxnPool for connecting to a remote
       cluster without the ability to ping.

VERSION

       version 7.717

SYNOPSIS

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

DESCRIPTION

       The Static::NoPing connection pool (like the Static pool) should be used when your access
       to the cluster is limited.  However, the "Static" pool needs to be able to ping nodes in
       the cluster, with a "HEAD /" request.  If you can't ping your nodes, then you should use
       the "Static::NoPing" connection pool instead.

       Because the cluster cannot be pinged, this CxnPool cannot use a short ping request to
       determine whether nodes are live or not - it just has to send requests to the nodes to
       determine whether they are alive or not.

       Most of the time, a dead node will cause the request to fail quickly.  However, in
       situations where node failure takes time (eg malfunctioning routers or firewalls), a
       failure may not be reported until the request itself times out (see "request_timeout" in
       Search::Elasticsearch::Cxn).

       Failed nodes will be retried regularly to check if they have recovered.

       This class does Search::Elasticsearch::Role::CxnPool::Static::NoPing 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 node  in round robin fashion - either a live node which has
       previously responded successfully, or a previously failed node which should be retried. If
       all nodes are dead, it will throw a "NoNodes" error.
