Heterogeneous batches are OK
editHeterogeneous batches are OK
editIt is possible to queue up heterogeneous batches of requests. For example, you can queue up several GETs, indexing requests and a search:
$client = ClientBuilder::create()->build(); $futures = []; $params = [ 'index' => 'test', 'type' => 'test', 'id' => 1, 'client' => [ 'future' => 'lazy' ] ]; $futures['getRequest'] = $client->get($params); // First request $params = [ 'index' => 'test', 'type' => 'test', 'id' => 2, 'body' => [ 'field' => 'value' ], 'client' => [ 'future' => 'lazy' ] ]; $futures['indexRequest'] = $client->index($params); // Second request $params = [ 'index' => 'test', 'type' => 'test', 'body' => [ 'query' => [ 'match' => [ 'field' => 'value' ] ] ], 'client' => [ 'future' => 'lazy' ] ]; $futures['searchRequest'] = $client->search($params); // Third request // Resolve futures...blocks until network call completes $searchResults = $futures['searchRequest']['hits']; // Should return immediately, since the previous future resolved the entire batch $doc = $futures['getRequest']['_source'];
