Change subject: engine: Introducing "cache" for ActionGroupDAO ...................................................................... engine: Introducing "cache" for ActionGroupDAO The following patch is introducing a simle cache for ActionGroupDAO. The following Dao only perfrom select operation from DB and never update operation. The following query is running during each engine bll comand, so introducing a cache will decrease dramaticly quries to DB. In general I would prefer to use some third-party cache solution which can be integrated inside dao, but because of it can some time, I just wrote something simple that should be good for now Change-Id: I292ed3cba6075064e13ba8cee73c47a018fa568a Signed-off-by: Michael Kublin <mkublin(a)redhat.com&gt; --- M backend/manager/modules/common/src/main/java/org/ovirt/engine/core/common/businessentities/ActionVersionMap.java M backend/manager/modules/dal/src/main/java/org/ovirt/engine/core/dao/ActionGroupDAODbFacadeImpl.java 2 files changed, 40 insertions(+), 1 deletion(-) Approvals: Michael Kublin: Verified; Looks good to me, approved -- To view, visit http://gerrit.ovirt.org/11546 To unsubscribe, visit http://gerrit.ovirt.org/settings Gerrit-MessageType: merged Gerrit-Change-Id: I292ed3cba6075064e13ba8cee73c47a018fa568a Gerrit-PatchSet: 2 Gerrit-Project: ovirt-engine Gerrit-Branch: master Gerrit-Owner: Michael Kublin <mkublin(a)redhat.com&gt; Gerrit-Reviewer: Barak Azulay <bazulay(a)redhat.com&gt; Gerrit-Reviewer: Eli Mesika <emesika(a)redhat.com&gt; Gerrit-Reviewer: Michael Kublin <mkublin(a)redhat.com&gt; Gerrit-Reviewer: Yair Zaslavsky <yzaslavs(a)redhat.com&gt;
