Compress the EIS name in the bqual
Project: JBoss Transaction Manager
Issue Type: Enhancement
Security Level: Public (Everyone can see)
Reporter: Tom Jenkinson
Fix For: 4.15.4
Current most of the bqual is consumed by the EIS name (stored uncompressed) leaving little space for future enhancements. This was OK before, but there is potentially a requirement to use some of the bqual to store a node identifier (which, in the gtrid is able to be 36 bytes long).
Jonathan has pointed out that we can maintain a file somewhere where the user passes us an EIS name of say "foo" and we can add this to the file as integer 1, and so on. This file can be reloaded at startup into a hashmap so that we can still print out the real EIS name even though the XID bqual would only consume 4 bytes now.
