The purpose of this project is to compare/contrast java and clojure implementations of naive matching (stock) price engine.
Expected hyposis is that:
- java implementation should be a bit faster (2-9 times)
- clojure implementation should be much shorter and modular
- bin - fat jars for the implementations
- jcmec - clojure implementation
- builds with leiningen
- uses ring (jetty 6x), moustache
- jcmegen - clojure client that generates input, calls into web service/s, verifies and prints results
- jcmej - java implementation
- builds with maven
- uses CXF (jetty 7x)
- build.sh - bash script that builds the implementations
- buid_run.sh - bash script wrapper that invokes build.sh and then run.sh
- config.clj - input configuration in clojure reader compatible format
- README.md - this file
- run.bat - Windows version of run.sh
- run.sh - invokes main of jcmegen against pre-build jars in bin
- REST JSON interface
- POST /match
- json: orderId (B|S plus sequence number), price
- GET /max/B|S
- GET /results
- GET /reset
- POST /match
- Support concurrent requests for match and get max buy and sell price.
- Return unmatched items.
- Reset internal state so matching session can be repeated.
./run.sh || run.bat
Make sure maven and leiningen are installed and on the PATH ./build_run.sh
- Port the rest of bash scripts to Windows bat
- Implement scala version
- Implement haskell version
- Collect run statistics: jcmegen will call into public web app which will store and report on run statistics.
