Issues & Decisions

Issue

Notes 

Decision

1

Review the use case returning all 50k cmHandle

Validity of the use case where ALL 50k CMhandle are expected to be returned everytime ?

AP Csaba Kocsis & kieran mccarthy 

 

AP CPS to report where they think scalability issues will occur.

2

Proposal to remove hazelcast for NCMP Module sync

The use of Hazelcast during NCMP's CM-handle Module Sync is leading to:

  1. High memory usage during CM-handle registration

  2. Consistency problem

  3. Poor load balancing between NCMP instances for module sync

Proposal to remove hazelcast from NCMP Module Sync requires an LCM State Machine Change. Need stakeholder input.

Proposal:  CPS-2161: Remove Hazelcast from NCMP Module Sync

Out of Scope

  • Datajob which is still in development are out of scope

  • For now Paging is out of scope, open to rescope depending on NCMP spike result
