PyOrient Client - data_cluster_data_range()

This method returns a range of Record ID's for the given cluster.

Retrieving Cluster Records

Using the data_cluster_data_range() method, you can retrieve all records stored in a particular cluster. You may find this particularly useful in implementations that organize similar records by storing them in dedicated clusters.


  • <cluster-id> Defines an integer for the Cluster ID.

For more information, see Clusters.


Consider the example of a smart home management application that maintains records using OrientDB. You have built a series of Arduino or Micro Python devices to monitor environmental conditions around the house, (that is, light, temperature, pollen levels, and so on), and have created a class in OrientDB to store data from these sensors. To better organize this data, for each room in your house you have a dedicated cluster to store records from these sensors.

# Retrieve Sensor Data
def get_sensor(client, cluster_id):

   # Retrieve Data
   data = client.data_cluster_data_range(cluster_id)
   return data

Here, the function receives the client object and an integer that indicates the Cluster ID for the room you want to access. It then calls the data_cluster_data_range() method with these arguments to retrieve all records in that cluster.
