Property Details

$activeNode public property

The active node. Key of one of the $nodes. Will be randomly selected on open().

public string $activeNode = null

$auth public property

Authentication data used to connect to the Elasticsearch node.

Array elements:

username: the username for authentication.
password: the password for authentication.

Array either MUST contain both username and password on not contain any authentication credentials.

public array $auth = []

$autodetectCluster public property

Whether to autodetect available cluster nodes on open()

public boolean $autodetectCluster = true

$connectionTimeout public property

Timeout to use for connecting to an Elasticsearch node. This value will be used to configure the curl CURLOPT_CONNECTTIMEOUT option. If not set, no explicit timeout will be set for curl.

public float $connectionTimeout = null

$dataTimeout public property

Timeout to use when reading the response from an Elasticsearch node. This value will be used to configure the curl CURLOPT_TIMEOUT option. If not set, no explicit timeout will be set for curl.

public float $dataTimeout = null

$defaultProtocol public property (available since version 2.0.5)

Default protocol to connect to nodes

public string $defaultProtocol = 'http'

$dslVersion public property

Version of the domain-specific language to use with the server. This must be set to the major version of the Elasticsearch server in use, e.g. 5 for Elasticsearch 5.x.x, 6 for Elasticsearch 6.x.x, and 7 for Elasticsearch 7.x.x.

public integer $dslVersion = 5

$nodes public property

The Elasticsearch cluster nodes to connect to.

This is populated with the result of a cluster nodes request when $autodetectCluster is true.

Additional special options:

auth: overrides $auth property. For example:

[
 'http_address' => 'inet[/127.0.0.1:9200]',
 'auth' => ['username' => 'yiiuser', 'password' => 'yiipw'], // Overrides the `auth` property of the class with specific login and password
 //'auth' => ['username' => 'yiiuser', 'password' => 'yiipw'], // Disabled auth regardless of `auth` property of the class
]

protocol: explicitly sets the protocol for the current node (useful when manually defining a HTTPS cluster)

public array $nodes = [['http_address' => 'inet[/127.0.0.1:9200]']]
