Create a Notification center section to show all the informations that worth
noting for users.
The idea is to surface timely and relevant updates that help users stay
aware of changes, issues, and opportunities related to their data infrastructure
### Here are some categories from my initial thinking:
1. System Alerts
These are mission-critical events that require user attention.
• Segment push failures or delays
• Real-time ingestion lag thresholds breached
• Controller/broker/server/minion node outages
• Low disk space or memory on servers
• Helix/ZooKeeper connectivity issues
• Schema or table config validation failures
2. New Features / System Updates
Highlight improvements or new capabilities introduced in Pinot or the UI.
• “New: Native ASOF joins now supported”
• “Improved: Ingestion metrics dashboard added to UI”
• “Updated: Segment metadata view now includes bloom filter stats”
These could be sourced from release notes, changelogs, or internal config
updates.
3. User-Facing Insights or Recommendations
Provide suggestions or analytics tips.
• “High query latency detected for table X – consider adding star-tree
index”
• “Table Y has low segment count – consider increasing segment push
frequency”
• “Query cache hit rate below 20% for broker Z – optimize query patterns”
4. Configuration Changes
Track important changes made to the system.
• “Table foo was updated by ad...@company.com”
• “Indexing strategy changed: inverted index added for column status”
• “Retention policy updated for table bar”
Include diffs or summaries where possible.
5. Security or Access Notifications
Transparency around access or policy enforcement.
• “New API token issued by user al...@company.com”
• “Access to table xyz granted to group analysts”
### For Implementation:
Store and display notifications with:
• Type: info / warning / error / success
• Severity/Priority
• Timestamps
• Actionable links or buttons (e.g. “View Segment Errors”)
