Summary: Make Unomi batchProfilesUpdate use ES scroll query
Key: UNOMI-430
URL: https://issues.apache.org/jira/browse/UNOMI-430
Project: Apache Unomi
Issue Type: Improvement
Reporter: romain.gauthier
Fix For: 2.0.0
*As a developer*
*I want to ensure good performances when calling batchProfilesUpdate described
here* https://unomi.incubator.apache.org/rest-api-doc/#-244007327*
h3. Acceptance criteria
When I call batchProfilesUpdate
Then Elasticsearch scrollquery should be used to ensure good performances
When I call batchProfilesUpdate
Then I should be able to configure the window size (1000) and the duration of
the scroll validity
h3. Designer notes
h3. Developer notes
This method
{code:java}
public void batchProfilesUpdate(BatchUpdate update) {
ParserHelper.resolveConditionType(definitionsService, update.getCondition());
List<Profile> profiles = persistenceService.query(update.getCondition(), null,
Profile.class);
for (Profile profile : profiles) {
if (PropertyHelper.setProperty(profile, update.getPropertyName(),
update.getPropertyValue(), update.getStrategy())) {
save(profile);
}
}
}
{code}
should be updated to something like:
{code:java}
public void batchProfilesUpdate(BatchUpdate update) {
ParserHelper.resolveConditionType(definitionsService, update.getCondition());
PartialList<Profile> profiles =
persistenceService.query(update.getCondition(), null, Profile.class, 0,1000,
"10m");
while (profiles.getList().size() > 0) {
for (Profile profile : profiles.getList()) {
if (PropertyHelper.setProperty(profile, update.getPropertyName(),
update.getPropertyValue(), update.getStrategy())) {
save(profile);
}
}
profiles = persistenceService.continueScrollQuery(Profile.class,
profiles.getScrollIdentifier(), profiles.getScrollTimeValidity());
if (profiles == null || profiles.getList().size() == 0) {
break;
}
}
}
{code}
