CONFIG_PROP_COLLECTOR_POOL_ARTIFACT

public static final String CONFIG_PROP_COLLECTOR_POOL_ARTIFACT

Flag controlling interning data pool type used by dependency collector for Artifact instances, matters for heap consumption. By default, uses “weak” references (consume less heap). Using “hard” will make it much more memory aggressive and possibly faster (system and Java dependent). Supported values: "hard", "weak".
