Overcoming Ubik Limitations

The current version of the Ubik subsystem prevents transactions of different types (reads / writes) from running at the same time, and prevents read-transactions during the recovery phase. These constraints can directly affect Ubik-using processes, leading to slow performance or even hangs. This presentation will provide an overview of the limitations mentioned above and the latest enhancements developed to overcome them.
