[jira] Commented: (JUDDI-431) find_tModel performance - 20s for
exact name + 3 KeyedReferences
[ https://issues.apache.org/jira/browse/JUDDI-431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12931831#action_12931831 ]
Lyudmil Latinov commented on JUDDI-431:
---------------------------------------
Performace quick win is in org.apache.juddi.api.impl.InquiryHelper.java - public static List<?> findTModel:
keysFound = FindTModelByNameQuery.select(em, findQualifiers, body.getName(), keysFound); to be moved on first place.
So first find based on Name criteria is performed and on those results find on CategoryBag criteria is performed.
For my usecase execution time was significantly reduced.

> I have jUDDI with DerbyDB with 440 tModels inside.
> When searching tModel for "exactMatch" name + CategoryBag with 2 KeyedReferences execution time is about 2s.
> When searching tModel for "exactMatch" name + CategoryBag with 3 KeyedReferences execution time is about 20s.
> With increasing number of KeyedReferences time for queue increases.
> Some performance improvements will be nice enhancement.
> Request for name + 2 KeyedReferences
