--------------------------------------
Summary: Consider removing metadata synchronization
Key: SIS-85
URL: https://issues.apache.org/jira/browse/SIS-85
Project: Spatial Information Systems
Issue Type: Improvement
Components: Metadata
Reporter: Martin Desruisseaux
Fix For: 0.3
All subclasses of {{ISOMetadata}} are currently synchronized. It probably
doesn't have significant impact on the JAR file size, since (in my
understanding) adding a {{synchronized}} keyword in the method signature just
set a bit in a bitmask. However it may be a cause of thread contention.
Synchronization may not be necessary since the typical usage of metadata
objects is:
* Create the metadata object once in a single thread.
* Declare the metadata as unmodifiable.
* Allow any thread to read (but not set) the metadata properties.
The potential contention, especially on metadata object shared by many other
objects, would be unfortunate. However profiling this not show significant
bottleneck yet.
