I'm in a bit of a predicament and hopefully someone will have some good advice. I am being cut back / limited to the amount of ram I can dedicate to the heap for my rule engine.
In general, I have a batch of 20k POJO's coming in (all 1 type), and 200-300 rules pattern matching the properties of those objects. If a rule fires, it will change a Boolean flag in a corresponding object. Im well aware that given how the rules are written (and optimized) as well as # of POJOs that it can greatly affect resource consumption. I noticed the Banking Benchmark on illation for use as a comparison, (http://blogs.illation.com.au/2009/08/performance-comparison-jess-vs-drools/comment-page-1/#comment-49) but still am not sure about the transaction number refered to 5k, 10k, etc POJO's in working memory or not (and the end result being a usage of appx 600mb RAM). Any rule of thumb would be much appreciated. Again, I am aware that it really depends on how you write/optimize your rules along with the batch size, but I don't want to sell myself short and not have enough ram. -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users y...@address.com' in the BODY of a message to majord...@sandia.gov, NOT to the list (use your own address!)
