Method: Elasticsearch::API::Utils#__bulkify

Defined in:
lib/elasticsearch/api/utils.rb

#__bulkify(payload) ⇒ Object

Convert an array of payloads into Elasticsearch ‘headerndata` format

Supports various different formats of the payload: Array of Strings, Header/Data pairs, or the conveniency “combined” format where data is passed along with the header in a single item.

Elasticsearch::API::Utils.__bulkify [
  { :index =>  { :_index => 'myindexA', :_type => 'mytype', :_id => '1', :data => { :title => 'Test' } } },
  { :update => { :_index => 'myindexB', :_type => 'mytype', :_id => '2', :data => { :doc => { :title => 'Update' } } } }
]

# => {"index":{"_index":"myindexA","_type":"mytype","_id":"1"}}
# => {"title":"Test"}
# => {"update":{"_index":"myindexB","_type":"mytype","_id":"2"}}
# => {"doc":{"title":"Update"}}
