Steven Hawkins resolved TEIID-1824.
-----------------------------------
Resolution: Done
Used threadlocal and even static factories where possible. On even moderately sized
documents (10s of thousands of elements) constructed predominately through xmlforrest,
there was an 80% reduction in runtime.
SQL/XML performance enhancement
-------------------------------
Key: TEIID-1824
URL:
https://issues.jboss.org/browse/TEIID-1824
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Affects Versions: 7.1
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 7.6
The sql/xml processing functions, xmlforrest, xmlelement, xsltransform, etc. make use of
stax factories by creating a newInstance each time. This is much too heavy-weight. The
factories should be shared as much as possible. The woodstox input/ouput factories in
particular can be static.
