Steven Hawkins resolved TEIID-2415.
-----------------------------------
Resolution: Done
Ensured that the properties object is thread-safe and made all mutable fields volatile to
ensure up-to-date reads.
Ensure thread-safety of mutable metadata
----------------------------------------
Key: TEIID-2415
URL: https://issues.jboss.org/browse/TEIID-2415
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 7.4
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.3
Some metadata values can be changed at runtime, such as transformations, stats, and
properties. In the case of transformations and stats an exception won't occur, but
the most up-to-date value may not be read by other threads. Changing the properties could
cause an exception as the map changes are not concurrency safe - similar to TEIID-2342
