Method: Elasticsearch::API::Indices::Actions#delete

Defined in:
lib/elasticsearch/api/actions/indices/delete.rb

#delete(arguments = {}) ⇒ Object

Delete indices. Deleting an index deletes its documents, shards, and metadata. It does not delete related Kibana components, such as data views, visualizations, or dashboards. You cannot delete the current write index of a data stream. To delete the index, you must roll over the data stream so a new write index is created. You can then use the delete index API to delete the previous write index.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :index (String, Array) —

    Comma-separated list of indices to delete. You cannot specify index aliases. By default, this parameter does not support wildcards (‘*`) or `_all`. To use wildcards or `_all`, set the `action.destructive_requires_name` cluster setting to `false`. (Required)

  • :allow_no_indices (Boolean) —

    If ‘false`, the request returns an error if any wildcard expression, index alias, or `_all` value targets only missing or closed indices. This behavior applies even if the request targets other open indices. Server default: true.

  • :expand_wildcards (String, Array<String>) —

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as ‘open,hidden`. Server default: open.

  • :ignore_unavailable (Boolean) —

    If ‘false`, the request returns an error if it targets a missing or closed index.

  • :master_timeout (Time) —

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error. Server default: 30s.

  • :timeout (Time) —

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error. Server default: 30s.

  • :error_trace (Boolean) —

    When set to ‘true` Elasticsearch will include the full stack trace of errors when they occur.

  • :filter_path (String, Array<String>) —

    Comma-separated list of filters in dot notation which reduce the response returned by Elasticsearch.

  • :human (Boolean) —

    When set to ‘true` will return statistics in a format suitable for humans. For example `“exists_time”: “1h”` for humans and `“exists_time_in_millis”: 3600000` for computers. When disabled the human readable values will be omitted. This makes sense for responses being consumed only by machines.

  • :pretty (Boolean) —

    If set to ‘true` the returned JSON will be “pretty-formatted”. Only use this option for debugging only.

  • :headers (Hash) —

    Custom HTTP headers

Raises:

  • (ArgumentError)
