ArcSDEDataStore thread safety compromised
-----------------------------------------
Key: GEOT-1732
URL: http://jira.codehaus.org/browse/GEOT-1732
Project: GeoTools
Issue Type: Bug
Components: data arcsde
Affects Versions: 2.5-M0
Reporter: Gabriel Roldán
Assignee: Gabriel Roldán
Fix For: 2.4.2, 2.5-M1
Thread safety is imposed by the fact sde connections are not thread safe and
transactions being run natively over a connection means multiple threads using
the same transaction hit the same connection.
Yet, the current lock mechanism is a nightmare to maintain, and small changes
may always break in unpredictable ways.
A new mechanism to ensure thread safety shall be implemented, but preferable
with enough granularity to not impose a huge performance penalty as serializing
access to an ArcSdeFeatureCollection/FeatureStore is. The plan is to divide the
usage of a connection in transaction into smaller execution tasks while
executing the tasks in a single thread so the connection is happy
