[jira] [Commented] (OLINGO-184) Performance optimization on edm primitve types

["Ralf Handl (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OLINGO-184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13917868#comment-13917868 ] 

Ralf Handl commented on OLINGO-184:
-----------------------------------

Which rules exactly are causing the performance problems?

This seems to be a good candidate topic for a "How to implement OData 4.0" committee note at OASIS.

>            Priority: Minor

> Edm primitive types are doing a lot of reg ex checks to be 100% compliant with OData 4.0 specification. These checks are very expensive in CPU consumption. 
> Maybe it is possible to avoid this checks (and instead of OData rules the Java type system rule will take place) or if that is not possible make them optional.
