Console - CREATE CLUSTER

Creates a new cluster in the current database. The cluster you create can either be physical or memory. OrientDB saves physical clusters to disk. Memory clusters are volatile, any records you save to them are lost when the server stops.

Syntax

CREATE CLUSTER <cluster-name> <cluster-type> <data-segment> <location> [<position>]
  • <cluster-name> Defines the name of the cluster.
  • <cluster-type> Defines whether the cluster is PHYSICAL or LOGICAL.
  • <data-segment> Defines the data segment you want to use.
    • DEFAULT Sets the cluster to the default data segment.
  • <location> Defines the location for new cluster files, if applicable. Use DEFAULT to save these to the database directory.
  • <position> Defines where to add new cluster. Use APPEND to create it as the last cluster. Leave empty to replace.

Example

  • Create a new cluster documents:

    orientdb> CREATE CLUSTER documents PHYSICAL DEFAULT DEFAULT APPEND

Creating cluster [documents] of type 'PHYSICAL' in database demo as last one...
PHYSICAL cluster created correctly with id #68

You can display all configured clusters in the current database using the CLUSTERS command. To delete an existing cluster, use the DROP CLUSTER command.
