COD now supports an improved auto-scaling algorithm that considers the latency of the user operations. COD now prioritises user operations over system operations that results in a reduced cost of infrastructure with a minor increase in replication.
This is available starting in COD v1.16 and you do not need to upgrade to a higher version of COD to benefit from this feature.
