2. Override policy enhancements provide better control over cluster-specific configurations.
3. Replica scheduling improvements enable better workload distribution.
4. Policy validation provides better validation of policy configurations.

Performance Optimizations

• Reconciliation optimizations reduce time to sync resources across clusters.
• Resource usage improvements reduce CPU and memory consumption.
• Network efficiency improvements reduce network overhead.
• Scaling improvements enable better handling of large numbers of clusters.

Integration Capabilities
