Query enhancements in 9.12
Apama 9.12 includes the following query enhancements:
A query may now also use the result of an action call on the event as the key for a query. For further information, see
Defining actions as query keys.
Coassignment in query files can now use the
as operator. For example:
using com.apama.aggregates.last;
query Example {
find Event as e select last(e.value) as lastValue without Stop as s {
}
}
Software AG Designer has been updated to use the
as operator when constructing queries graphically. The current
: assignment operator is still valid for backwards compatibility. For further information, see
Defining event patterns.
