Analytics
Team Manager: Nuria Ruiz


 * Make easier to understand the history of all Wikimedia projects
 * Release Mediawiki History in JSON/CSV or mysql dump format (the best dataset to measure content and contributors)


 * Make easier to understand how Commons media is used across our projects.
 * Work starting on mediarequests API to get statistics of view of individual Wikimedia images.


 * Increase Data Quality
 * Enthrophy-based alarms for data issues  work should be continued in Q2


 * Increase Data Privacy and Security

 * Modern Event Platform
 * * Continue moving events from job queue to event gate main. ✅
 * * Development work for kafka connect ❌ to next quarter
 * * Schema Repository CI for convention and backwards compatibility enforcement ✅


 * Operational Excellence. Increase Resilience of Systems
 * * New zookeeper cluster for tier-2
 * Operational Excellence. Reduce Operational Load by Phasing Out Legacy Systems
 * * Sunset MySQL data store for eventlogging.  this quarter and next.

 Status 
 * July 23, 2019 -
 * We will be moving any work that has to do with kafka connect to next quarter due to licensing issues. Thus marking as not done for this quarter.
 * Migration of Events to EventGate main has been rolling out w/o issues.
 * Work for mediarequests API started, probably API will be in service next quarter.
 * Enthrophy-based alarms for data issues - is done for this quarter and will be picked up next quarter.
 * August 2019 -
 * We are waiting for survey responses to finalize the format of the mediawiki history release.
 * Work continues on mediarequests API, we are working on backfilling this data on hive, once that is done we can move it to druid or cassandra so it can be served via API.
 * Migration of events from job queue to event gate main ahead of schedule, no production issues.
 * September 2019 -
 * Overall we will be finishing much of the work in progress early next quarter


 * Mediawiki history data is public, we are working on the hadoop process that will publish the files as current infrastructure on dumps is not sufficient to publish files fast enough


 * New Mediarequest API work planned for this quarter is done, we have a deployment pending in order to make it public
 * Slightly blocked on hardware for the zookeeper task, working with DC ops.

Release Engineering
Team Manager: Greg Grossmeier

Priority: Reduce complexity of the platform to make it easier for new developers to contribute.

 * - All applicable new and existing services (and partially MediaWiki) exist in the Deployment Pipeline
 * Migrate restrouter ✅
 * (Stretch): MobileContentService is now
 * (Stretch): Preparatory MediaWiki config clean-up & static loading work
 * - Actionable code health metrics are provided for code stewards
 * Scope out requirements for a self-hosted version of SonarQube for our use is
 * Expand set of repositories covered by code health metrics (via SonarQube)
 * - Provide a standardized local MediaWiki development environment
 * Migrate local-charts to deployment-charts is - -
 * Instantiate testing and linting of helm charts - -
 * Preliminary work on a CLI for setup/management - -

Dependencies on: SRE, Code Health Metrics WG

Core: Developers have a consistent and dependable deployment service.

 * - Iteratively improve our deployment tooling, service, and processes.
 * Streamline the Kibana -> Phab error reporting workflow (using client-side code, at first)
 * - Align developer services with SRE best practices.
 * Work with SRE to identify and implement needs of Phabricator and Gerrit (expected to last into Q2)

Dependencies on: SRE, Performance

Core: Maintain and improve the Continuous Integration and Testing services

 * - Maintain CI and testing services
 * Scope updated CI/testing KPIs
 * Set up an experimental elastic search instance to store and analyze CI logs and metrics ❌
 * - Evaluate, select, and implement a new CI infrastructure.
 * POCs of GitLab and Zuul3 systems (as well as argo); evaluate options
 * Document an implementable architecture for what we want in new CI

Dependencies on: SRE/Others invested in CI architecture choices

Core: A clear set of unit, integration, and system testing tools is available for all supported engineering languages.

 * - Update the existing system test tooling and developer education.
 * Update existing Selenium documentation (https://www.mediawiki.org/wiki/Selenium/Node.js)

Dependencies on: none.

 Status 
 * July 25, 2019 -
 * Migrate restrouter is ✅ and is now in Services's team hands
 * Some portions of SonarQube is not open sourced, so we're looking into options
 * Streamline the Kibana -> Phab error reporting workflow - has a POC now and should be deployed soon
 * August 27, 2019 -
 * For the work to streamline the Kibana -> Phab error reporting workflow e're looking at deploying Phatality
 * POC for GitLab is ✅ and Zuul3 is
 * Scope out requirements for a self-hosted version of SonarQube is no longer stalled. We have a strategy that will use a combination of self-hosted and cloud hosted depending on the data. Essentially, self-hosted open source version will not do branch level analysis.  We don't believe that will keep us from using it for non-branch based analysis.
 * Expand set of repositories covered by code health metrics (via SonarQube) - we will have three new extensions added by the end of this month, and adding 3-6 more next month.
 * Set up an experimental elastic search instance to store and analyze CI logs and metrics: We met to discuss this under the "Data ^3" project and laid out some basic objectives for a POC, and this work will continue into next quarter.
 * Update the existing system test tooling and developer education:
 * We worked with the Core Platform team in the analysis and selection of a an integration test tool. The expectation is for the Quality and Test Engineering team to take responsibility for this tooling once a SET is in place.
 * Code Health Metrics WG has spun off effort to separate existing MediaWiki Unit Tests from Integration tests (driven by WMDE)
 * September 2019 -



Research
Team Manager: Leila Zia
