It seems that the rules-users list is experiencing either massive
delays or duplicate delivery.
See message below which reached me today.
Should you experience the same effect, I have indicated this to
"rules-users-owner" so it is known
Cheers,

Betreff: [rules-users] CEP functionality
Antwort an: Rules Users List <rules-users(a)lists.jboss.org>
Dear all,
We posted this question two weeks ago, but with no replies. please
forgive
me for posting it again.
In our business, most of the facts have time-stamp attributes. For
example,
each laboratory test (a fact) has the time stamp when the sample was
taken,
and when the machine produced the result value. In our business-
logic, we
often analyze the relation between facts using these attributes.
For example:
1) finding two adjacent labResults with an increasing value
2) checking whether 3 facts are consecutive
3) counting the number of facts fulfilling a specific constraint
within a
specific time window.
We were happy to read (in the blog) about the new CEP feature which
is about
to be added to drools 5.0.
* Where can we find a more detailed description of CEP functionality
in
drools?
* Is it a good idea to use CEP for analyzing historic data
(retrieved from
the database)? or is it best for online data.
