Monthly Planning and Focus

Completed Sprint - Sprint 215 (Dec 8- Jan 2) - LINK TO Jira Spring 215

Current Sprint  - Sprint 216 (Jan 9 - Feb 2) - Sprint 216

For the month of December 2023, the Mayo group is planning to:

  • Complete Report Exporter banner

  • Improvements, Refactoring Code Debt, Feature development:
  • Examine feasibility of Java 17
    • BACKGROUND: a small number of LexEVS components (aka dependencies) are being phased off of java 8 (or are no longer being supported on java 8).  We ideally want to use a current version of those components (dependencies). IF the current version of that component is only supported on Java 14 or later (just as an example), then we would have to migrate the ENTIRE LexEVS stack to Java 14 or later. (Note that the current Java version is Java 21 LTS, and the most popular non-LTS version is Java 14). So there is a risk that a vulnerability is found in the older version of the component/dependency and we would have to either migrate everything quickly to a new version, or not use that component (which might not be possible), or shutdown LexEVS entirely. Note that there are certain versions of Java which are "long-term support" versions - meaning that they will be supported for several years beyond non-LTS versions. LTS versions are Java 8,  Java 11, Java 17, and Java 21.
    • OBJECTIVE: find out what would it be like to upgrade from Java 8 LTS to Java 17 LTS.  How hard would it be? How long might it take?
    • LEXEVS-5373Investigate Upgrade of NCIt Browser to Java 17
  • DataDog

Technical Debt remediation

LexEVS Code Debt Refactoring

  • Coding complete on lexevs services - except for isolated dependencies
    • Java 17 work ready for NCit Browser 
  • CTS2 - Working to update Jakarta - linked to Java17
  • Dependabot notice to update jQuery - ready for Dev

OS Updates
  • Mark has meeting with Shiv on Thursday, Jan 25. Initial discussions.reached out to Krish, Eric Williams and are waiting to hear back.
  • Jason provided list of AWS hosts Number of hosts now around 30 -(24 hosts on AWS need to move to new Amazon Linux 23
  • AL23 an option for on-prem. Decide between AL23 and Oracle Linux
  • Lyubov asked if extension is possible - especially since we have not yet received a formal notification
  • CentOS EOL June 30, 2024
  • )
Report Exporter
  • Banner changes being implemented  - in progress
    • for on cloud → will be using CBIIT's injection
    • for on-prem → will be using our own implementation
    • Per Lyubov, could they implement centralized approach on prem
    • Systems did implement config change but ineffective. Requested roll back
    • Local banner approach being worked on
  • Working on templating - Need user feedback for phase 2
    • Demo feedback implemented
    • Need to make more dynamic - load values from external source - work started
    • Will need feedback from users to provide template requirements
  • Wait time indicator work is being tested
  •  Mark to schedule meeting with editors for feedback; Mark has sent out poll for times

ACTION: (from Lyuba) We don't have any indication that the tool is working. Can we get an indicator, like a spinning circle, etc.
