High Time execution retrieve RTC workitem history


Arturo San Feliciano (4511010) | asked Nov 05 '13, 3:13 a.m.
  Hello,

    I´m developing a JobStream with datamanager to get workitems history but the time elapsed on the process is very high (not too much records 51474). Which could be the causes? how can improve the performance?

   I use the xdc files downloaded from rtc server and the query on DataManager is (select all attributes of Wi history on 5 project areas):

SELECT "resolutionDate",
"workflowSurrogate",
"typeId",
"ownerItemId",
"resolutionName",
"projectAreaItemId",
"creationDate",
"creatorItemId",
"id",
"dueDate",
"stateId",
"modified",
"duration",
"resolutionId",
"href",
"resolverItemId",
"priorityId",
"contextId",
"stateName",
"summary",
"severityId",
"modifiedByItemId",
"targetItemId",
"categoryItemId",
"foundInItemId",
"priorityName",
"description",
"typeName",
"severityName",
"tags",
"itemId",
"stateGroup",
"teamAreaItemId",
"uniqueId",
"correctedEstimate",
"timeSpent",
"parentUniqueId",
"parentItemId",
"dayModified",
"commentCount",
"subscriberCount",
"projectAreaArchived",
"name",
"creatorUniqueId",
"ownerUniqueId",
"resolverUniqueId",
"floatComplexity",
"integerComplexity",
"doubleComplexity",
"longComplexity",
"stringComplexity",
"DATASOURCE_ID"
FROM   "WORKITEM_CCM"."WorkItem"
where projectAreaItemId ='_8yYyQI1rEeKhwYZgctl45w'
or projectAreaItemId ='_ppY1gIczEeK829ZH5BxfIw'
or projectAreaItemId ='_v28WsKgeEeKGsdKVPE2-rQ'
or projectAreaItemId ='_lR1CkMkiEeKvAcjHViGEdg'


    The DM log shows:
