    Constant Field Values
  - GG_POINT_IN_TIME_FETCHING_POOL_SIZE
```
public static final String GG_POINT_IN_TIME_FETCHING_POOL_SIZE
```

```
public static final String GG_POINT_IN_TIME_STORED_TX_INTERVAL
```
    This property specifies the time window in milliseconds for storing all committed transactions in the recovery phase. This property allows the implementation to reduce heap usage. The default value is 20 000 milliseconds.
    
    See Also:
    
    Constant Field Values
  - GG_EXCHANGELESS_POINT_IN_TIME_RECOVERY
```
public static final String GG_EXCHANGELESS_POINT_IN_TIME_RECOVERY

  - GG_LICENSE_HOST_MAC_INTERSECTION
```
public static final String GG_LICENSE_HOST_MAC_INTERSECTION
```
    When true (default), the license processor groups cluster nodes into physical hosts by the intersection of their network interface MAC sets (two nodes that share at least one MAC are considered the same host), instead of requiring an exact match of the whole ATTR_MACS string. This prevents the license CPU/host count from inflating when co-located nodes capture different MAC snapshots at JVM startup. Set to false to fall back to the legacy exact-string host grouping.
