Does the RuleEngine evaluate rules concurrently or sequentially?

[anshulk-arch]

In a given workflow with N rules, does the RuleEngine execute these rules concurrently or sequentially from 1 to N e.g. in the workflow below, will it execute GiveDiscount10 and GiveDiscount20 in parallel or, one after the other? If sequential, is it possible to execute rules sequentially?

[
{
"WorkflowName": "Discount",
"Rules": [
{
"RuleName": "GiveDiscount10",
"SuccessEvent": "10",
"ErrorMessage": "One or more adjust rules failed.",
"ErrorType": "Error",
"RuleExpressionType": "LambdaExpression",
"Expression": "input1.country == "india" AND input1.loyaltyFactor <= 2 AND input1.totalPurchasesToDate >= 5000"
},
{
"RuleName": "GiveDiscount20",
"SuccessEvent": "20",
"ErrorMessage": "One or more adjust rules failed.",
"ErrorType": "Error",
"RuleExpressionType": "LambdaExpression",
"Expression": "input1.country == "india" AND input1.loyaltyFactor >= 3 AND input1.totalPurchasesToDate >= 10000"
}
]
}
]

As per my understanding, it does sequentially. So if there are two rules in one workflow which fulfill the condition, the execution will stop after the first one
