OClass - truncateCluster()
This method removes all data from the given cluster.
Truncating Clusters
Classes can have several clusters that they use to store records. When your application has been running for a while, you may encounter issues that require basic or drastic housekeeping on class clusters. Use this method when you need to remove all data from a cluster, such as when the records are obsolete or no longer necessary.
Note that after you call this method, OrientDB needs to rebuild indexes on the class.
