ca.sqlpower.architect.profile
Class LocalReservoirProfileCreator

java.lang.Object
  ca.sqlpower.architect.profile.AbstractTableProfileCreator
      ca.sqlpower.architect.profile.LocalReservoirProfileCreator

All Implemented Interfaces:

TableProfileCreator

public class LocalReservoirProfileCreator
extends AbstractTableProfileCreator

A profile creator that takes a statistical sample of the rows in the table and then performs the profiling operation on that sample. The profiling is done inside the local JVM, which means that a known set of aggregates will be computed for each data type, regardless of the remote database platform's support for aggregating different data types. For example, this profiler will always calculate the average date of a date column.

Unless the network connection to the remote database is very slow, expect this profile creator to be much faster than the RemoteDatabaseProfileCreator, especially on large tables.
