NAME

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

VERSION

SYNOPSIS

13           $e = Search::Elasticsearch->new(
14               cxn_pool => 'Static'     # default
15               nodes    => [
16                   'search1:9200',
17                   'search2:9200'
18               ],
19           );
20

DESCRIPTION

22       The Static connection pool, which is the default, should be used when
23       you don't have direct access to the Elasticsearch cluster, eg when you
24       are accessing the cluster through a proxy.  It round-robins through the
25       nodes that you specified, and pings each node before it is used for
26       the first time, to ensure that it is responding.
27
28       If any node fails, then all nodes are pinged before the next request to
29       ensure that they are still alive and responding.  Failed nodes will be
30       pinged regularly to check if they have recovered.
31
32       This class does Search::Elasticsearch::Role::CxnPool::Static and
33       Search::Elasticsearch::Role::Is_Sync.
34

CONFIGURATION

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