  • :wait_for_active_shards (String) —

    Sets the number of shard copies that must be active before proceeding with the bulk operation. Defaults to 1, meaning the primary shard only. Set to ‘all` for all shard copies, otherwise set to any non-negative value less than or equal to the total number of copies for the shard (number of replicas + 1)

  • :refresh (String) —

    If ‘true` then refresh the affected shards to make this operation visible to search, if `wait_for` then wait for a refresh to make this operation visible to search, if `false` (the default) then do nothing with refreshes. (options: true, false, wait_for)

  • :_source_includes (List) —

    Default list of fields to extract and return from the _source field, can be overridden on each sub-request

  • :pipeline (String) —

    The pipeline id to preprocess incoming documents with

  • :require_alias (Boolean) —

    Sets require_alias for all incoming documents. Defaults to unset (false)

  • :require_data_stream (Boolean) —

    When true, requires the destination to be a data stream (existing or to-be-created). Default is false

  • :list_executed_pipelines (Boolean) —

    Sets list_executed_pipelines for all incoming documents. Defaults to unset (false)

  • :headers (Hash) —

    Custom HTTP headers

    Specify if request cache should be used for this request or not, defaults to index level setting
