Drools Expert stays the recommended default approach. A) Drools DRL score calculation (the default, recommended way) * Positive: o Flexibility: score rules can be written in decision tables xls, guvnor, ... o Fast incremental calculation for free: no need to write boilerplate code for it * Negative: o Learning curve for DRL o Polygot fear (some companies don't like adding an extra language as DRL in the mix) B) Simple Java score calculation * Positive: o Easy to write o No learning curve (plain old java) o Fast prototyping: existing score calculation code can be reused * Negative: o Very slow, not scalable (no incremental calculation at all) C) Incremental Java score calculation: * Positive: o Very fast and scalable * Negative: o Users need to write a lot of difficult boilerplate code for incremental calculation. -- This message is automatically generated by JIRA.
