Hi Alan,
I did the same experiment, with the same variable names too :) have a look
at the github issue.
Finally I discovered prevayler calls reset method on oos every time it
writes to it. This is why the overhead is written every time. Klaus,
prevayler author, says it is so to prevent leaks an
You must be doing something wrong, or describing your method badly, because
the vector [:a1 1] doesn't take nearly that much space in my experiments.
The first object you write to a stream requires quite a bit of overhead,
but after that future objects are relatively cheap. Here's an example you
Yes. I suggested nippy. The question is about the size of Java serialized
Clojure data structures. Can a two element vector be 1kB in size? Why
serialization in my REPL experiment (see the code following the link in my
previous mail) produces a 80MB byte buffer while prevayler logs are 1GB?

You should probably look at Clojure-specific solutions, starting with EDN
(i.e. essentially pr-str), fressian, transit or nippy.
Clojure data structures have a lot of properties that can be exploited (we
only care about the abstract type and the actual data), so a serializer can
make a lot of assu
