Subject [jira] Created: (DDLUTILS-258) Degradation of performance of Table when using DdlUtils with a large dataset
Date Sun, 25 Apr 2010 18:02:00 GMT
Degradation of performance of Table when using DdlUtils with a large dataset
----------------------------------------------------------------------------

                 Key: DDLUTILS-258
                 URL: https://issues.apache.org/jira/browse/DDLUTILS-258
             Project: DdlUtils
          Issue Type: Improvement
          Components: Core (No specific database)
    Affects Versions: 1.1
            Reporter: Tom Palmer
            Assignee: Thomas Dudziak
            Priority: Minor


When using DdlUtils to load large amounts of data I've observed a drop-off in performance
originating in the Table class. It uses an ArrayList to store its columns, foreign keys and
indicies but treats the contents as a Set within the equals, hashCode and sortForeignKeys.
On one particular project I've observed up to 2 minutes of the overall load time being consumed
in these methods.
