Hi all,
I'm modifying xmlworkflow aspect to add xref to mets.xml in each cell of
owned items table (page /submissions). The change works well, but I found
an issue when I did a batch import with 900> items through workflow, the
page response is too slow. The code is the below:
int count = 0;
Row row = table.addRow();
for (ClaimedTask owned : ownedItems)
{
int workflowItemID = owned.getWorkflowItemID();
String stepID = owned.getStepID();
String actionID = owned.getActionID();
XmlWorkflowItem item = null;
try {
item = XmlWorkflowItem.find(context, workflowItemID);
Workflow wf =
WorkflowFactory.getWorkflow(item.getCollection());
String url =
contextPath+"/handle/"+item.getCollection().getHandle()+"/xmlworkflow?workflowID="+workflowItemID+"&stepID="+stepID+"&actionID="+actionID;
if(count%3 ==0 && count != 0){
row = table.addRow();
}
String url_item =
"/metadata/internal/item/"+Integer.toString(item.getItem().getID())+"/mets.xml";
Cell cell_reference =row.addCell();
cell_reference.addXref(url,message("xmlui.XMLWorkflow."
+ wf.getID() + "." + stepID + "." + actionID));
cell_reference.addXref(url_item);
count++;
} catch (WorkflowConfigurationException e) {
row = table.addRow();
row.addCell().addContent("Error: Configuration error in
workflow.");
log.error(LogManager.getHeader(context, "Error while
adding owned tasks on the submissions page", ""), e);
} catch (Exception e) {
log.error(LogManager.getHeader(context, "Error while
adding owned tasks on the submissions page", ""), e);
}
The output is a table with many rows, and each row contains 3 cells with
references to items in workflow. The problem seems construct this structure
is too hard (queries in postgresql to obtain the list of owned items in
xmlworkflow are fast so seems not a problem of database query), but I don't
understand why construct this kind of structures in XML is so expensive.
Someone have more than 500-600 items in workflow and can confirm the
response of the page is slow?
Thanks in advance
