detecting retries
It seems that an important part of optimizing the performance of a Clojure application may be to attempt to minimize the number of retries that are performed in transactions. What are good ways to detect and count retries other than explicitly adding code inside dosync calls to count them? -- R.

Re: detecting retries
+1 I think two simple atomic integers would do the trick: 1. Number of transactions entered 2. Number completed, or exited through exception. The amount 1 exceeds 2 is your retry rate.

I could implement this myself in every transaction, but I'm looking for tools that do this or something provided with Clojure ... this is if such a thing exists.

Re: detecting retries
The last I looked it would need to be added at the Java level.
