Mis behaving entity-list cache clear

Kumaraswamy nandipati
Hi.,

I am working on cache management. while updating ProductPrice(supposed
entity) for one product, whole entity-list cache for
ProductPrice("entitycache.entity-list.default.ProductPrice") was getting
cleared. i.e, if my 20K product Prices were cached at some time point , if I
updated price for one product, all the ProductPrice entity-list cache was
getting cleared. While looking this problem, I am suspecting some code in *
AbstractEntityConditionCache.java*<http://svn.apache.org/repos/asf/ofbiz/branches/release09.04/framework/entity/src/org/ofbiz/entity/cache/AbstractEntityConditionCache.java>storeHook()
method,

// QUESTION: what is this? why would we do this?
               if (!oldMatched && isPK) {
                    //Debug.logInfo("In storeHook, for entityName [" +
entityName + "] oldMatched is false and isPK is true, so setting
shouldRemove to true (will remove from cache)", module);
                    Debug.logInfo("shouldRemove made as true.....for
oldMatched", module);
                    shouldRemove = true;
                }


This code block was playing role to clear all the entity-list cache for a
perticular entity. Surprisingly, I find some question was asking for this
block(commented code above this block.)
*
*My Question was*:
1) Can anybody please update me is there any other reason why we need to
cache-clear for entire entity-list cache for that entity if suppose I
changed for one *GenericValue??.

*2) If there is no purpose for this code block, Why we need this?*

**
