[teiid-issues] [JBoss JIRA] Closed: (TEIID-743) Excessive cloning of connector binding properties

Excessive cloning of connector binding properties ------------------------------------------------- Key: TEIID-743 URL: https://jira.jboss.org/jira/browse/TEIID-743 Project: Teiid Issue Type: Bug Components: Common Affects Versions: 6.1.0 Reporter: Ramesh Reddy Assignee: Ramesh Reddy Fix For: 6.2.0 The connector binding properties are excessively being cloned at each level, which leads to lot if memory overhead. In the case of handling the hundreds of connector bindings this will result in OOM. 1) The connector binding properties does not have access to the configuration level properties (properties in deploy.properties) 2) Default property mechanism not being used. When you create a properties object like "new Properties(defaultProps)", the defaultProps object properties are not copied into the container properties object, nor they can be changed. They can be overridden, but will not affect the defaultProps object. 3) Properties not being cached For (2) connector binding properties need to be layered such that the connector binding property tree object will look like system properties |-------------------------> deploy.properties |------------------> Connector Type Properties |----------------------------> Connector Binding Properties For (3) since up to the "Connector Type Properties", are common for a given Connector Binding they should be cached to minimize the memory overhead.
