The transaction management is built on top of a fork of the *HBase-trx* project implementing the following changes: -* Upgraded it to work on HBase version 0.98.1 (for CDH 5.1) or 0.98.0 (for HDP 2.1). +* Upgraded it to use the HBase coprocessor mechanism. * Added support for parallel worker processes doing work on behalf of the same transaction. -* Added support for global transactions, that is, transactions that can encompass resources (regions/HTables) across an HBase cluster. +* Added support for global transactions, that is, transactions that can encompass resources (regions/Tables) across an HBase cluster. * Added transaction recovery after server failure. There is on Distributed Transaction Manager (DTM) process per node in a cluster running Trafodion. The DTM process owns and keeps track of all transactions that were started on that node. (In HBase-trx, transactions were tracked in the library code of each client, which meant that after a server failure, there was no way to restart the transaction manager for in-doubt transactions.)
