If the coherence of a cluster node is below the minimum coherence, what does the Analytics engine do?

When the coherence of a cluster node falls below the minimum threshold, the Analytics engine recognizes that the cluster may not be functioning optimally. This condition often indicates that the data within the cluster is insufficiently interconnected or lacks the necessary data integrity to support effective processing and analysis.

In response to this situation, the engine breaks up the cluster into subclusters. This action allows for better resource allocation and improved performance, as smaller subclusters can operate more efficiently and independently. This restructuring aims to enhance the coherence of the data being analyzed, ultimately leading to more accurate and reliable results.

The other options presented would not align with standard practices for managing cluster coherence. Merging clusters or deleting them would not address the coherence issue effectively. By creating subclusters, the system can maintain operational integrity and optimize analysis capabilities.
