---------------------------------------
Optimisation example on ContactMechWorker.getPartyContactMechValueMaps
[^OFBIZ-10514.patch]
I will continue to analyse if this introduce no regression and I continue on
others entities
> Refactoring ContactMechWorker.get[Entity]ContactMechValueMaps

> ContactMechWorker.get[Entity]ContactMechValueMaps are old historic functions
> that resolve all contact mech context related to an Entity (Party, Facility,
> Order, WorkEffort).
> The problem that they create too many db call during their execution that
> decrease OFBiz performance when the contactMech history grow.
> On customer site I realized a new adaptation (oriented and not generic at
> all) and control the performance issue with a unit test :
> {code:java}
> public void testContactMechSearch() throws Exception {
> UtilTimer timer = new UtilTimer("test contactmech", true, true);
> timer.startTimer();
> List<Map<String, Object>> cmwPostalAdress =
> ContactMechWorker.getPartyContactMechValueMaps(delegator, "10375", false,
> "POSTAL_ADDRESS");
> timer.timerString("PA cmw " + cmwPostalAdress.size());
> List<Map<String, Object>> cmwTelecomNumber =
> ContactMechWorker.getPartyContactMechValueMaps(delegator, "10375", false,
> "TELECOM_NUMBER");
> timer.timerString("TN cmw " + cmwTelecomNumber.size());
> List<Map<String, Object>> cmwEmail =
> ContactMechWorker.getPartyContactMechValueMaps(delegator, "10375", false,
> "EMAIL_ADDRESS");
> timer.timerString("E cmw " + cmwEmail.size());
> List<Map<String, Object>> epwPostalAdress =
> CustomPartyWorker.getPartyContactMechValueMaps(delegator, "10375", false,
> "POSTAL_ADDRESS", null);
> timer.timerString("PA cpw " + epwPostalAdress.size());
> List<Map<String, Object>> epwTelecomNumber =
> CustomPartyWorker.getPartyContactMechValueMaps(delegator, "10375", false,
> "TELECOM_NUMBER", null);
> timer.timerString("TN cpw " + epwTelecomNumber.size());
> List<Map<String, Object>> epwEmail =
> CustomPartyWorker.getPartyContactMechValueMaps(delegator, "10375", false,
> "EMAIL_ADDRESS", null);
> timer.timerString("E cpw " + epwEmail.size());
> }
> {code}
> The partyId "10375" is linked with more tha 600 contactMechs on my local site
> db. And the test excecution give :
> {code:java}
> With ContactMechWorker
> [java] [[PA cmw 2- total:....,since last(Begin):33.707]] - 'test
> contactmech'
> [java] [[TN cmw 2- total:....,since last(PA cmw 2):33.837]] - 'test
> contactmech'
> [java] [[E cmw 1- total:1..,since last(TN cmw 2):33.115]] - 'test
> contactmech'
> With CustomPartyWorker
> [java] [[PA epw 2- total:...,since last(E cmw 1):0.53]] - 'test
> contactmech'
> [java] [[TN epw 2- total:...,since last(PA epw 2):0.588]] - 'test
> contactmech'
> [java] [[E epw 1- total:...,since last(TN epw 2):0.631]] - 'test
> contactmech'
> {code}
> total ~100s for ContactMechWorker and ~1.5s for CustomPartyWorker
> Difference come that CustomPartyWorker works on a view entity gathering the
> data and populating GenericValue with makeValue (using the data within the
> view) instead of creating new getRelated db access.
> I will implement this idea on generic context to improve these functions
