From c76392f0491e357b444b3458cc26649f7dc1e7fb Mon Sep 17 00:00:00 2001 From: DylanB95EST Date: Fri, 11 Feb 2022 12:46:27 +0000 Subject: Fragment handling decreasing performance for large number of cmHandles - allow fragmentEntity to set parent id (needed for optimization) - updated addListAlement and addChildDataNode to use new common optimized metghod to add to exsiting children - ensure methods are transactional - Refactored test around adding list elements to clearly define test checking the presence of grandchild element Issue-ID: CPS-886 Change-Id: Ic4381f0f7170ebd666d5bc8aa6ef2c4548d81766 Signed-off-by: DylanB95EST --- .../org/onap/cps/spi/entities/FragmentEntity.java | 3 ++ .../spi/impl/CpsDataPersistenceServiceImpl.java | 56 ++++++++-------------- 2 files changed, 24 insertions(+), 35 deletions(-) (limited to 'cps-ri/src/main/java') diff --git a/cps-ri/src/main/java/org/onap/cps/spi/entities/FragmentEntity.java b/cps-ri/src/main/java/org/onap/cps/spi/entities/FragmentEntity.java index 00d1d98df3..2fdfa0528f 100755 --- a/cps-ri/src/main/java/org/onap/cps/spi/entities/FragmentEntity.java +++ b/cps-ri/src/main/java/org/onap/cps/spi/entities/FragmentEntity.java @@ -70,6 +70,9 @@ public class FragmentEntity implements Serializable { @Column(columnDefinition = "text") private String xpath;
