Brian,
How does the Gearman solution to de-duplication work ?
Might be wandering off topic.. if so please reply off list.
Is it part of Moxi ?
Does Gearman have a key on the query in the queue to avoid duplicates ?

So, one common use for Gearman seems to be running SQL queries
through it so that a given query only ever is running once at a
given time. This solves one big issue I have seen with a cache
stampede. The application servers all run the same queries at the
same time. Pushing this logic down to the database server seems like
a good idea from where I sit. The server could recognize that there
are N connections all running the same query and not try and do all
the work needed to send back the result.
What do you guys think? Does this make sense at the database layer?
Is the drizzle plugin architecture able to support this type of
behavior?
