[英]Elasticsearch 2 + PHP scroll flow issue
Hi can somebody tell me please how to execute scroll on Elasticsearch 2 via PHP Ruflin\\Elastica library?嗨,有人能告诉我如何通过 PHP Ruflin\\Elastica 库在 Elasticsearch 2 上执行滚动吗? According documentation for ES2 first scroll request should lead to specific index while next requests are called without index with only scroll_id parameter.根据 ES2 的文档,第一个滚动请求应该导致特定的索引,而下一个请求在没有索引的情况下仅使用 scroll_id 参数调用。 So I wrote this code:所以我写了这段代码:
/** @var Elastica\Client $elastic */
$elastic = $container->getService( 'elastica' );
// This first call works fine. I get the scroll_id.
$elasticScrollData = $elastic->getIndex( 'event' )->request( '_search?scroll=5m', 'GET', ['size' => 500, 'sort' => ['_doc']] )->getData();
$countAll = $elasticScrollData['hits']['total'];
saveToMongo( $elasticScrollData, $countAll, $elastic );
function saveToMongo( $scrollData, $countAll, \Elastica\Client $elastic )
{
$documents = [];
foreach ( $scrollData['hits']['hits'] as $item )
{
$doc = [];
$doc['ico'] = (array)$item['_source']['ico'];
...
$documents[] = $doc;
}
try
{
saveDataToDb( $documents );
}
catch( \Exception $e )
{
echo '+++ insert exception: ' . $e->getMessage() . "\n";
}
// Here is the problem. It throws me an exception: No enabled connection
$scrollData = $elastic->request( '_search/scroll', 'GET', ['scroll' => '5m', 'scroll_id' => $scrollData['_scroll_id']] )->getData();
saveToMongo( $scrollData, $countAll, $offset, $elastic, $mongoCollection );
}
What is wrong with the second call to Elasticsearch?第二次调用 Elasticsearch 有什么问题? Why it throws error: No enabled connection?为什么会抛出错误:没有启用的连接? Hope somebody knows cause I really dont.希望有人知道,因为我真的不知道。
The Elastica\\Client
use a round-robin connection pool by default to resolve connectivity issue, If all connections are gone, It throw ClientException
with message No enabled connection
1 . Elastica\\Client
默认使用循环连接池来解决连接问题,如果所有连接都消失了,它会抛出ClientException
并带有消息No enabled connection
1 。
Check your network connectivity between PHP script and Elasticsearch and review your configuration for Elasticsearch.检查 PHP 脚本和 Elasticsearch 之间的网络连接并检查 Elasticsearch 的配置。
