Enrico Olivelli created OPENJPA-2820:
----------------------------------------

             Summary: Track when a DBIdentifier is already delimited in order to save memory allocations and cpu
                 Key: OPENJPA-2820
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2820
             Project: OpenJPA
          Issue Type: Improvement
          Components: performance
    Affects Versions: 3.1.3
            Reporter: Enrico Olivelli


During the development of [https://github.com/apache/openjpa/pull/69/files] [~rmannibucau] suggested to keep track of the fact that a DBIdentifier contains a name that has been already delimited, this way operations like "removeDelimiters" can be no-op.

 

This flag can be set during the creation of a DBIdentifier by the DBDictionary, basically when the DBIdentifier forces delimitAll=true
