[EAP][CD][7.2] scale up, new EAP pod ready before it joined the cluster, sessions lost during merge

    XMLWordPrintable

Details

    • CLOUD Maintenance Sprint 27

    Description

      With current EAP builds (EAP CD, EAP 7.2) When scaling up (under load), the time it takes the new node to join the cluster seems to be significantly higher that it is with jboss-eap-7/eap71-openshift:1.3.

      More imporantly, in our test scenario, the new pod is ready before it joins the cluster (so it is receiving traffic) and the sessions such initiated are lost when the node joins the rest of the cluster.

      Scenario: simple <distributable/> servlet, storing an integer counter into session
      scaling from 2 to 3 under load (256 clients with random 0-20s delay before each request), no encryption, openshift.DNS_PING

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) CLOUD-3029 [EAP] - Update openshift-ping to 1.2.3-Final

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) JGRP-2313 Promote GMS message "[...] creating cluster as first member" to INFO level

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
