Hi! I am a student at Swansea University (UK), trying to present a Project about Clojure STM performance and Java Locks performance during the simulation of concurrent Banking transactions:
I intend to execute a concurrent transfer of (fixed amount of) money from an account A to an account B in a dosync with a concurrent transfer from account B to account A and repeat this conflict a N- input number times. Like this: (transfer account-a account-b 100) (transfer account-b account-a 100) Now, I don't think I am doing it right because i am not taking full advantage of the STM, while I should perform on large sets of shared objects to make the difference between STM and Locks. FINALLY: What I would like to do is: 1) connect to a database with the Accounts, and create an associated data that works with STM. 2) Create N-random operations Like (account id-source, account-id- destination, money) 3) Start counting time -> perform the operations under STM -> stop counting time. 4) update the database and show statistics. QUESTION: which kind of clojure data should I use in the point 1) to make advantage of STM transactions? which database best suit the fact that I will use the same data to perform operations in Clojure and in Java (one at a time) ? I know mySQL at least :P I really need some advice, I also would like to ear your opinion on the other points (2,3,4). Many thanks in advance!!
