- filtered statements count (by if expression)
- nested execution statements count (count output rows of a query)
- processing start time for query and scripting elements (e.g. to
measure the time a long running query execution runs before delivering
the first row to scriptella
- configurable query element based commit for batched connections (e.g.
to set explicite commit after query element execution has ended to flush
containing (eventually batched) scripting elements. Thus following
non-batched connection can read the committed result.
