PhpOrient - dataClusterCount()

This method returns a count of records in the given cluster.

Counting Records

In certain situations you may find it useful to check how many records a given cluster contains, for instance as part of logging or debugging, or to check cluster size before running a backup script.

Syntax

$client->dataClusterCount(<clusters>)

• <clusters> Defines the cluster or clusters you want to count on.

Example

Picture a web application where you want to count records in a given cluster. For instance, on a blog site you might want a basic count to show the number of entries you host on the site across several entries.

function countBlogs(){

    // Fetch Global Client
    global $client;

    // Return Record Count
    return $client->dataClusterCount(
        $client->getTransport()->getClusterMap()->getIdList());
}
