Hi,
another way if it's not an enumeration or the like:
(doseq [entry (repeatedly #(.getNextEntry stream)) :while entry]
(println (.getName entry)))
Kind regards

This doesn't really answer your question directly, but is there a reason you
need to keep this in clojure, or are you just aiming to establish why this is
happening?
My understanding was that for performance critical code the general advice is
to drop down to raw java?

Hi Jason,
Have you guys taken a look at core.matrix for any of this stuff? We're also
shooting for near-Java-parity for all of the core operations on large
double arrays.

But only one task was active at a time, although Executors was configured
with 4 threads. It occurred to me that map itself is lazy and it is realized
in doseq one at a time. A possible fix is to use for instead of map to
generate tasks

The benefit is that your migrations are just Clojure functions. No messing

I hope someone extracts it into a lib with tests around
The laziness of map is irrelevant here, because .invokeAll is treating it

just as lazy. What's actually changed is that your map and for produce

That is a good point. But another reason I wanted to do migrations through
the application code was to automagically run migrations when the app was
initially run, i.e. do a lein ring server-headless and it will

There are also following libraries to handle migrations:
Ragtime: https://github.com/weavejester/ragtime
Lobos: https://github.com/budu/lobos
Lobos has its own DSL to implement database manipulation. Ragtime uses
normal Clojure functions instead.

We used drift for a while, but found it didn't add much over plain sql, and
