| The XT transactional database engine will drive the next generation of the PrimeBase Database server. XT will add a number of important features to PrimeBase 5, these include:
64-bit support - unlimited table size
Currently only PrimeBase BLOB data may be unlimited in size. Regular
table data is limited to a total of 2GB per table. By nature of its
design, XT has no such restriction. More details on the XT design can
be found in the White Paper.
Full Multi-processor Support
The XT engine is built to minimize bottlenecks and conflicts that occur
in a symmetric multi-processor environments. For example, each active thread
has its own transaction log in order to reduce write contension.
Historical Snapshot Support
With XT it is possible to draw a so-called "historical snapshot". This
means an image of the database can be created which reflects a
consistent view of the database at a previous point in time. Extremely
useful, for example, if data is deleted by accident.
