CIMRelation

class CIMRelation extends BaseRelation with TableScan with CIMRDD

A Relation for CIM RDF files that can produce all of its tuples as an RDD of Row objects.

As a side effect, this relation also creates RDD and local temporary views corresponding to the subclasses of each element, and saves each RDD in the persistent RDD list using the CIM class name.

    Example:

    Persist the typed RDD using the given name, checkpoint it if that is enabled, and create the SQL view for it.

    Persist the typed RDD using the given name, checkpoint it if that is enabled, and create the SQL view for it.

    Since the use of RDD persistence can be problematic for memory reuse, the keep parameter has special processing. When keep is true any existing RDD of the same name is renamed to name|n where n is sequentially increasing to the next available integer. When keep is false all existing RDD of the above form are unpersisted.

    This facilitates the use-case where the new RDD depends on the existing one. For example, the Elements RDD is rewritten by about, dedup, join, normalize and topological processing, where the new RDD is derived from the original. But when a completely new CIM RDF file is read in, keep=false will unpersist all the derived RDD.

    T

    The type of RDD.

    rdd

    The RDD to persist

    name

    The name under which to persist it.

    keep

    If true then don't unpersist the existing RDD with the given name.

    spark

    The Spark session.

    storage

    The storage level for persistence.

    returns

    The named, viewed and possibly checkpointed original RDD.
