Pushing asynchrony further into the stack is useful for reliability and
fault tolerance. We can also use it as a basis for Complex Event Processing
using time series windows.

Thanks Ashish. We will certainly add to the list of interesting subjects.

So items such as ML and other 'big data' related topics will be in our

That's great feedback.
We can (and will) definitely improve the notes along the lines you suggest.

I asking too much ... in other words I have got this far and I should be
expected to know the answer (I really feel like I should too by the way!)
Use of the term Clojurians?
Something else?
Thanks

Fantastic answer Marc - I had been fiddling about with map and hash maps

I am missing something obvious... I get a list of maps back from a function
and I want to find the elements with nil
(({:a2p-id 1, :dh-uuid abc-def-ghi-klm} {:a2p-id 2, :dh-uuid
def-ghi-klm-opq} {:a2p-id 3, :dh-uuid nil}) ({:a2p-id 1, :dh-uuid
abc-def-ghi-klm} {:a2p-id 2, :dh-uuid
note the double parentheses. That is a list (or
sequence), whose first element is a list (or sequence) of maps. You can
use (first (map find-records query-parts)) to get the inner list.

On the other hand ... does that mean that the sequence being filtered is
not lazy?

It's as I presented it - a list of a list of maps

The list of maps is retained which might be useful
I am starting out to use Clojure to combine and verify data between DB2 on
a Mainframe, SQL Server and an Atom Feed. Yes, it's such fun working in a
start-up ;-)
Database wise, all is connecting OK after some Leiningen shenanigans and I
am now stuck on the mapping part ;-)
The code is below.

Of course, I haven't tested any of this, so plenty of opportunity for

This code is different to what you posted the other day
and pasted those two function definitions, and did not
get the errors you are seeing. I don't have a good guess why you are
getting those errors. Did you do the require first? What version of
Clojure are you using?

My fellow Clojurians,
I am having a trouble hunting down an example of the above stack for
clojure applications.
Can anyone point me in the right direction?
Thanks
