Enrico Daga commented on CLEREZZA-890:
--------------------------------------
With CLEREZZA-889 all operations done by MGraphs are delegated to the
DataAccess class. The DataAccess class uses a single connection and preserve
prepared statements. Connections are renewed each statements 10000 executions.
Different renewal policies may be implemented in the future.
> Use prepared statements and reuse connections in Virtuoso data operations to
> improve performance

> Currently, each operation is encapsulated in a dedicated connection and
> statement. While this is functional, it is not very performant, especially
> with the pattern based on atomic triple additions and deletions used by the
> clerezza model. Statements should be prepared, connections reused.
