Thanks Andy! And, I take it from the timestamps that they're shown in
the order in which they're executed.
In the order logged - logging happens "live" as the engine runs. Don't
forget ARQ may be using an iterative pipeline so things seem to occur
multiple times.

When I execute the following query with ARQ and the -v parameter,
PREFIX : <http://some/uri/>
SELECT * WHERE {
OPTIONAL { ?s :comment ?comment . }
?s :firstName ?firstName ; :lastName ?lastName .
}
I see the following in the output:
11:53:02 INFO exec :: BGP :: (?s <http://some/uri/firstName>
?firstName) (?s <http://some/uri/lastName> ?lastName)
11:53:03 INFO exec :: Reorder :: (?s <http://some/uri/firstName>
?firstName) (?s <http://some/uri/lastName> ?lastName)
11:53:03 INFO exec :: BGP :: (?s <http://some/uri/comment>
?comment)
11:53:03 INFO exec :: Reorder :: (?s <http://some/uri/comment>
?comment)
I can see the reordering that was done (especially if I rerun the query
with optimize=off) but can someone tell me or point me to documentation
of what "BGP" vs. "Reorder" mean in these INFO messages?
"BGP" is the BGP to be executed; "Reorder" is the same BGP but after
reordering.
