----------------------------------------
Summary: Provide Ability To Pass JPA / EclipseLink Properties to
the DataSource
Key: AMBARI-16207
URL: https://issues.apache.org/jira/browse/AMBARI-16207
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Affects Versions: 2.4.0
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Fix For: 2.4.0
There is currently no way to pass JPA or EclipseLink specific
connection/DataSource properties in from {{ambari.properties}}. Although there
exists {{Configuration.getDatabaseCustomProperties}}, these are actually
_driver specific_ properties and not properties for EclipseLink.
For example, if I wanted to pass in to the JDBC Driver {{foo=bar}}, then I
could set
{{server.jdbc.properties.foo=bar}} and this will get translated into
{{eclipselink.jdbc.property.foo=bar}}.
However, if I wanted to set any of the EclipseLink or JPA specific DataSource
properties (see
http://www.eclipse.org/eclipselink/api/2.6/org/eclipse/persistence/config/PersistenceUnitProperties.html)
I would not be able to.
Proposal is to add something similar to the custom driver properties:
{code}
server.persistence.properties.eclipselink.jdbc.batch-writing.size=25
{code}
Which could get translated into
{code}
properties.put("eclipselink.jdbc.batch-writing.size", 25)
{code}
