Improve xml/json production --------------------------- Key: TEIID-2390 URL: https://issues.jboss.org/browse/TEIID-2390 Project: Teiid Issue Type: Enhancement Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 8.4.1, 8.5 The current xml/json logic can produce a lot of intermediate results that are recopied and can result in a slower performance for larger documents. The logic could allow for nested evaluations to delay creating their full string forms or simply allow the return values to remain appendable rather than requiring full copies.
