# Search::Elasticsearch::CxnPool::Static::NoPing(3pm)

A CxnPool for connecting to a remote cluster without the ability to ping.

## NAME

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

## VERSION

version 8.12

## 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.
