| ||75.0||The native memory usage threshold for the circuit breaker. Memory usage must be below this percentage of |
| ||false||True when memory usage exceeds the |
| ||50%||The native memory limit for graphs. At the default value, if a machine has 100 GB of memory and the JVM uses 32 GB, the k-NN plugin uses 50% of the remaining 68 GB (34 GB). If memory usage exceeds this value, k-NN removes the least recently used graphs.|
