--------------------------------------
Summary: Add possibility to disable QueryCache by default (new
config property)
Key: OPENJPA-2543
URL: https://issues.apache.org/jira/browse/OPENJPA-2543
Project: OpenJPA
Issue Type: Improvement
Components: jdbc
Affects Versions: 2.3.0
Reporter: Jörn Gersdorf
As discussed on the [openjpa-user
MailingList|http://mail-archives.apache.org/mod_mbox/openjpa-users/201411.mbox/%3CCALLZsMnXPQT%2BeQB3VjYe4U05%2BgSR%2Bw37QqXGRdxdvM-kgEXdLw%40mail.gmail.com%3E]
I need to enable the OpenJPA QueryCache in a selective way, i. e. it should be
disabled unless I enable it explicitly using
query.getFetchPlan().setQueryResult(true).
I´ve figured out that this requires
{{FetchConfigurationImpl$ConfigurationState#queryCache}} to be set to false by
default, however, there does not seem to be a configuration property for this.
So I propose a new configuration property like
{{openjpa.jdbc.QueryCacheDefaultState}}, defaulting to {{true}} (the current
default), with possibility to set to {{false}}. This would set the property
{{FetchConfigurationImpl$ConfigurationState#queryCache}} accordingly.
