SVN commit: Bug#328937 - partitioning support https://bugs.eclipse.org/bugs/show_bug.cgi?id=328937 design, http://wiki.eclipse.org/EclipseLink/DesignDocs/328937 Changes: Changes: - added batch-fetch example - added partitioned, and isolated partitioned version of UnitOfWork test
model, uses "virtual rack" (multiple connection pools to the same
database) - added partitioningPolicy to ClassDescriptor - added null check to FetchGroupManager to avoid null-pointer on failed
deploy - added PartitionPolicy abstract class, defines getConnections API - added ReplicationPolicy, replicates writes to multiple pools - added pool reference to Accessor, so it knows where it came from - added acquire/release connection logging - added partitioningPolicy to AbstractSession - changed AbstractSession accessor to Collection accessors (and updated references) - changed transaction to work with multiple accessors (2 stage commit) - changed call execution to work with multiple accessors - made client sessions (isolated, exclusive) execute calls consistently,
added support for partitioning - added @Overrides to sessions, some micro - fixed finally connection release in ReferenceMapping - changed DatabaseQuery accessor to Colleciton accessors - changed SessionBroker getAccessor API to use same getAccessor for partitioning, only a single call, pass query - added setURL to DatabaseLogin - changed ClientSession writeAccessor to Map writeAccessors keyed on
pool name - changed ClientSession connection to be lazily assigned - changed getAccessor on ClientSession to assign a connection if in a transaction to support backward compatiblity, and internal usage - changed ServerSession call execution to support partitioning - added JPA partitioned model - changed JPA test framework methods to be instances methods and use
inherited getPersistenceUnitName define in test avoid common mistakes in non
default unit tests - added JPA paritioning test switch using derby "cluster" and
round robin and replication, tests only run on Derby as need to create multiple
databases - added JPA annotations and xml - made partition policies named - fixed JPA orm.xml reading to only parse the xml with the correct
project/schema, not with all three, so correct error is returned Code review: Andrei, Guy |
