[rules-users] Jbilling Drools performance

Tue May 18 17:11:26 EDT 2010

Greg,

CDR is a Call Detail Record, sorry I forgot to explain it, the object is a
POJO with the following attributes:

field: name: datereference type: DATE value: 2010-04-28 00:00:00.0
field: name: billingid type: STRING value: 20100428.15544.42adf
field: name: accountid type: INTEGER value: 15544
field: name: billingperiod type: STRING value: 20100401
field: name: billingclassification type: STRING value: DUR
field: name: ipxcallguid type: STRING value:
5k692927-guwtka-g8kj8d0u-1-g8krry54-o4n
field: name: transactiondatetime type: DATE value: 2010-04-28 20:21:01.337
field: name: billingitemid type: INTEGER value: 0
field: name: ratesystem type: STRING value: IPXNET
field: name: originnumber type: STRING value: 551135880520 at bitcompany.braste
field: name: destinationnumber type: STRING value: 551139012650
field: name: destinationareaid type: STRING value: 100000551
field: name: chargedduration type: DATE value: 1980-01-01 00:02:06.0
field: name: chargedamount type: FLOAT value: 0.0816
field: name: userid type: INTEGER value: 3372
field: name: username type: STRING value: bitcom51
field: name: unitamount type: FLOAT value: 0.00389
field: name: amountcurrency type: STRING value: USD
field: name: timezone type: INTEGER value: -3
field: name: registertype type: STRING value: MV
field: name: datelastupdated type: DATE value: 2010-04-29 02:57:18.54
field: name: lastupdatedby type: STRING value: IPXRateCalls rev032
field: name: lastupdateremarks type: STRING value: null
field: name: dateinserted type: DATE value: 2010-04-29 02:57:18.54
field: name: destinationdetail type: STRING value: SAO PAULO
field: name: type type: STRING value: Fixo
field: name: collectedcallflag type: INTEGER value: 0
field: name: jb_timestamp type: DATE value: null
field: name: digit0 type: INTEGER value: 5
field: name: digit1 type: INTEGER value: 5
field: name: digit2 type: INTEGER value: 1
field: name: digit3 type: INTEGER value: 1
field: name: digit4 type: INTEGER value: 3
field: name: digit5 type: INTEGER value: 9
field: name: digit6 type: INTEGER value: 0
field: name: digit7 type: INTEGER value: 1
field: name: digit8 type: INTEGER value: 2
field: name: digit9 type: INTEGER value: 6
field: name: digit10 type: INTEGER value: 5
field: name: digit11 type: INTEGER value: 0

This spreadsheet is only a sample because the whole one has 40000 rules, I'm
checking the Jbilling code, but it seams to be loading the rules each time.
