[ http://issues.apache.org/jira/browse/DERBY-1674?page=comments#action_12429501 ] Daniel John Debrunner commented on DERBY-1674: ----------------------------------------------
Simple stats on class count and sizes in insane mode (from the classes folder, not size in the jar). Revision: 432856 Number of RowFactory classes 21 Size of RowFactory classes 169252 org/apache/derby/iapi/sql/dictionary Number of Dictionary api classes 47 Size of Dictionary api classes 216108 org/apache/derby/impl/sql/catalog Number of Catalog impl classes 36 Size of Catalog impl classes 360173 > Investigate reducing the number of classes & methods in DataDictionary used > to represent system tables > ------------------------------------------------------------------------------------------------------- > > Key: DERBY-1674 > URL: http://issues.apache.org/jira/browse/DERBY-1674 > Project: Derby > Issue Type: Improvement > Components: SQL > Reporter: Daniel John Debrunner > Assigned To: Daniel John Debrunner > Priority: Minor > > Currently two classes exists for each system table, one to represent the > table (e.g.SYSTABLESRowFactory) , one to represent a row (e.g. > TableDescriptor) > Look at having a single row factory (CatalogRowFactory) and using > polymorphism (method overloading) on the descriptor objects to perform the > work > that is done today (e.g. converting a descriptor to and from a Row object). > In addition the DataDictionary has a specific method to drop each type of > unique descriptor (e.g. dropSPSDescriptor, dropAliasDescriptor) > Would it be possible to have a single > dropDescriptor(UniqueSQLObjectDescriptor) method and again use polymorphism > on the descriptors. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
