(was: 10.0.0.Alpha3)
XidImpl implementations can optimize some byte[] allocations
------------------------------------------------------------
Key: ISPN-9778
URL:
https://issues.jboss.org/browse/ISPN-9778
Project: Infinispan
Issue Type: Bug
Components: Transactions
Reporter: William Burns
Priority: Major
Fix For: 10.0.0.Beta1
The EmbeddedXid and XidImpl classes show up on profiler for allocating byte[] in a local
environment.
1. We should be able to remove the branch byte[] completely as well as its accompanying
AtomicInteger and just return an empty byte[] that is cached (ie. Util.EMPTY_BYTE_ARRAY).
2. We can use the byte[] that is provided from the create method directly in XidImpl,
which would reduce our allocation to just the 1 byte\[24\] for embedded or byte\[32\] for
remote.
-3. We can return the byte[] directly for getGlobalTransactionId without copying.-
