- Data normalization efforts are shifting closer to the data source to reduce central processing burdens on the Gord system.
- A new library will be introduced to define required data fields for upstream sources, reducing iteration for correct data submission.
- Long-term objectives include eliminating Gord's internal data representation in favor of a pipeline with consistent type structures.
- Static substreams are being evolved into a dynamic system allowing users to submit logical specifications or predicates for specific data subsets.
- Gord system rollout frequency is planned to increase from the current monthly schedule as testing capabilities improve.
- The team aims to implement a 24/7 operating model for Gord using dynamic folding of boxes to eliminate scheduled shutdowns and reboots.
- Recruiting outreach will expand through "Women in STEM," "Insight," and the specific "InFocus" program targeting underrepresented minorities in tech.
