String[] keyValue = sCondition.split("=");
if (keyValue.length != 2) {
throw new SettingsException("Invalid condition: '{}'; format must be 'condition=value'"; sCondition);

var condition = keyValue[0];
var value = keyValue[1];
if (MaxSizeCondition.NAME.equals(condition)) {
valueParser.addMaxIndexSizeCondition(value; setting);
