The following two steps may help:

Ulises, thanks for the response. The insertions will be sprinkled out
over time and would want insertions/removals to be reasonably
efficient.

Hi Islon,
Records already implement java.io.Serializable. So this is working:
(ns record-serialization)
(defrecord R [x y])
(defn test-serialization
[]
(with-open [oos (java.io.ObjectOutputStream.
(java.io.FileOutputStream. "tmp"))]
(.writeObject oos (R. 12 42)))
(with-open [ois (java
There are a couple of different things being discussed here. I don't
think there's any harm in allowing maps as frames, as long as people
understand that they're arbitrarily ordered (alphabetically by key,
but that's an implementation detail) and that keys specified aren't
optional - if they're no

Yes, java serialization is what I want but I don't know how to do a
record implement the Serializable interface.

Maybe Microsoft has tuned the CLR for those particular benchmarks

Lau,
This is really impressive, and I can't wait to experiment with it.
That said, I'm curious as to what good use cases for this would be,
and what it's motivation is. SQL is already a highly specialized DSL
for slinging around relational data that most developers are already
pretty good with. I

We use a combination of apache common logging and log4j.
In dev we can remove log4j and still have some decent console logging.

Normally I release the jar to clojars when I implement some major

Good question. The solution didn't make the cut for my initial
release, but will be added soon. My plan is to have an (ordered-
map ...) frame which encodes and decodes the keys in the given order.
So for C interop, the frame would be
(ordered-map :a :int16, :b :float32)
An alternative would be

Yes. There are Eclipse license headers on all the files, I'll just

This looks a *lot* like something I did a long time ago ("Data File

Any sugestions?
