Conditionals

Equals

Checks if the value at a key equals a specified value.

Overview

The equals condition evaluates whether a field's value exactly matches a specified value. It works with strings, numbers, booleans, arrays, and objects, making it one of the most versatile conditions for exact matching scenarios.

Use Cases

• Status Matching: Route based on exact status values
• Boolean Flags: Check feature flags or boolean fields
• Exact Value Filtering: Filter for specific numeric or string values
• Object/Array Comparison: Compare complex nested structures

Configuration

Setting	Type	Required	Description
key	string	Yes	The field path to check. Supports dot notation for nested fields. Use * to check all keys.
value	any	Yes	The value to compare against. Can be string, number, boolean, array, or object.
case_insensitive	boolean	No	If true, performs case-insensitive string comparison.
not	boolean	No	If true, inverts the condition (matches if values are NOT equal).

Value Format

Internally, all values are stored as strings. This means 123 matches both the number 123 and the string "123" in your data. To match only a specific type, wrap the value in quotes:

Input	Matches
hello	"hello"
123	123 (number) and "123" (string)
"123"	"123" (string only, not the number 123)
true	true (boolean) and "true" (string)
"true"	"true" (string only, not the boolean true)
["a","b"]	["a","b"] or ["b","a"] (order-independent)
{"k":"v"}	{"k":"v"}

Use quotes when you need to distinguish between a string and its numeric or boolean equivalent.

Examples

String Comparison

Check for exact string match:

Code
{
  "type_id": "equals",
  "config": {
    "key": "status",
    "value": "active"
  }
}

Matches:

Code
{"status": "active"}

Does not match:

Code
{"status": "Active"}
{"status": "active "}
{"status": "inactive"}

Case-Insensitive String Comparison

Match strings regardless of case:

Code
{
  "type_id": "equals",
  "config": {
    "key": "status",
    "value": "active",
    "case_insensitive": true
  }
}

Matches:

Code
{"status": "active"}
{"status": "Active"}
{"status": "ACTIVE"}

Numeric Comparison

Check for exact numeric value:

Code
{
  "type_id": "equals",
  "config": {
    "key": "priority",
    "value": 1
  }
}

Matches:

Code
{"priority": 1}
{"priority": 1.0}

Does not match:

Code
{"priority": 2}
{"priority": "1"}

Boolean Comparison

Check boolean fields:

Code
{
  "type_id": "equals",
  "config": {
    "key": "is_active",
    "value": true
  }
}

Matches:

Code
{"is_active": true}

Does not match:

Code
{"is_active": false}
{"is_active": "true"}

Array Comparison (Unordered)

Compare arrays - order does not matter:

Code
{
  "type_id": "equals",
  "config": {
    "key": "tags",
    "value": ["a", "b", "c"]
  }
}

Matches:

Code
{"tags": ["a", "b", "c"]}
{"tags": ["c", "a", "b"]}
{"tags": ["b", "c", "a"]}

Does not match:

Code
{"tags": ["a", "b"]}
{"tags": ["a", "b", "c", "d"]}

Object Comparison (Unordered)

Compare objects - key order does not matter:

Code
{
  "type_id": "equals",
  "config": {
    "key": "config",
    "value": {"enabled": true, "timeout": 30}
  }
}

Matches:

Code
{"config": {"enabled": true, "timeout": 30}}
{"config": {"timeout": 30, "enabled": true}}

Does not match:

Code
{"config": {"enabled": true}}
{"config": {"enabled": true, "timeout": 30, "extra": "field"}}

Nested Field Comparison

Check values in nested fields:

Code
{
  "type_id": "equals",
  "config": {
    "key": "user.role",
    "value": "admin"
  }
}

Matches:

Code
{"user": {"role": "admin", "name": "John"}}

Not Equal Check

Match records where the value is NOT equal:

Code
{
  "type_id": "equals",
  "config": {
    "key": "status",
    "value": "deleted",
    "not": true
  }
}

Matches:

Code
{"status": "active"}
{"status": "pending"}

Does not match:

Code
{"status": "deleted"}

Wildcard Key Check

Check if any field equals a value:

Code
{
  "type_id": "equals",
  "config": {
    "key": "*",
    "value": "critical"
  }
}

Matches:

Code
{"severity": "critical"}
{"priority": "critical"}
{"status": "critical"}

Common Patterns

Status-Based Routing

Route by exact status:

Code
{
  "operator": "and",
  "conditions": [
    {"type_id": "equals", "config": {"key": "type", "value": "order"}},
    {"type_id": "equals", "config": {"key": "status", "value": "shipped"}}
  ]
}

Feature Flag Check

Route based on feature flags:

Code
{
  "operator": "and",
  "conditions": [
    {"type_id": "equals", "config": {"key": "features.new_checkout", "value": true}},
    {"type_id": "equals", "config": {"key": "features.beta_user", "value": true}}
  ]
}

Environment Routing

Route production vs non-production:

Code
{
  "operator": "and",
  "conditions": [
    {"type_id": "equals", "config": {"key": "environment", "value": "production"}},
    {"type_id": "equals", "config": {"key": "region", "value": "us-east-1"}}
  ]
}

Null Check

Check for null values:

Code
{
  "type_id": "equals",
  "config": {
    "key": "deleted_at",
    "value": null
  }
}

Matches:

Code
{"deleted_at": null}

Does not match:

Code
{"deleted_at": "2024-01-15"}
{"id": "123"}

Note: A missing field is different from a null value. Use key_exists to check for missing fields.

Exclude Specific Values

Filter out specific statuses:

Code
{
  "operator": "and",
  "conditions": [
    {"type_id": "equals", "config": {"key": "status", "value": "deleted", "not": true}},
    {"type_id": "equals", "config": {"key": "status", "value": "archived", "not": true}}
  ]
}

Best Practices

1. Use exact types: Ensure the value type matches your data (1 vs "1", true vs "true").

2. Use case_insensitive when appropriate: For user-generated content or when case may vary.

3. Remember array comparison is unordered: ["a", "b"] equals ["b", "a"].

4. Remember object comparison is unordered: Key order doesn't matter for equality.

5. Use equals_any for multiple values: If checking against several possible values, equals_any is more readable.

6. Null vs missing: Use equals with null to check for null values; use key_exists to check for missing fields.

Type Handling

Data Type	Behavior
Strings	Direct comparison (case-sensitive by default)
Numbers	Numeric comparison (1 equals 1.0)
Booleans	Direct comparison (true vs false)
Arrays	Unordered deep comparison (same elements in any order)
Objects	Unordered deep comparison (same keys/values, any key order)
Null	Matches only null values (not missing fields)

Limitations

• Single value comparison (use equals_any for multiple values)
• case_insensitive only applies to string comparisons
• Missing fields return false (not equal to anything, including null)

Troubleshooting

String not matching:

• Check for exact case (use case_insensitive: true if needed)
• Look for trailing spaces or hidden characters
• Verify encoding (special characters)

Number not matching:

• Ensure value is a number, not a string (1 vs "1")
• Check for floating point precision issues

Boolean not matching:

• Use actual boolean values (true/false), not strings
• Check if your data source serializes booleans as strings

Array not matching:

• Ensure all elements are present
• Remember comparison is unordered
• Check for duplicate handling (duplicates must match)

Null not matching:

• A missing field is not the same as null
• Use key_exists with not: true to check for missing fields
