NAME

OpenSearch::Client::Transport - Provides interface between the client class and the OpenSearch cluster

VERSION

version 3.007005

DESCRIPTION

The Transport class manages the request cycle. It receives parsed requests from the (user-facing) client class, and tries to execute the request on a node in the cluster, retrying a request if necessary.

This class does OpenSearch::Client::Role::Transport and OpenSearch::Client::Role::Is_Sync.

CONFIGURATION

send_body_as_source

$os = OpenSearch::Client->new(
    send_body_as_source => 1
);

The body is encoded as JSON and added to the query string as the source parameter. This has the advantages for those filtering on request method but has the disadvantage of being restricted in size. The limit depends on the proxies between the client and OpenSearch, but usually is around 4kB.

METHODS

perform_request()

Raw requests can be executed using the transport class as follows:

$result = $os->transport->perform_request(
    method => 'POST',
    path   => '/_search',
    qs     => { from => 0, size => 10 },
    body   => {
        query => {
            match => {
                title => "OpenSearch clients"
            }
        }
    }
);

Other than the method, path, qs and body parameters, which should be self-explanatory, it also accepts:

ignore

The HTTP error codes which should be ignored instead of throwing an error, eg 404 NOT FOUND:

$result = $os->transport->perform_request(
    method => 'GET',
    path   => '/index/type/id'
    ignore => [404],
);

serialize

Whether the body should be serialized in the standard way (as plain JSON) or using the special bulk format: "std" or "bulk".
