Data Caching (Redis)

Set Cache Value

redis.set {
  key = ""
  data = ""
  ttl = 0
}

Parameter	Purpose	Example
key	Cache key identifier	`"user:123"`, `"session:abc"`
data	Value to store	`"data"`, `{user: "john"}`
ttl	Time-to-live in seconds	`300`, `3600`

Example

redis.set {
  key = "user:"|add:$user.id
  data = $user.profile
  ttl = 3600
}

Stores a value in cache
Optional TTL for expiration
Overwrites existing values

Get Cache Value

redis.get {
  key = ""
} as x1

Parameter	Purpose	Example
key	Cache key to retrieve	`"user:123"`
as	Alias for retrieved value	`x1`, `cached_data`

Example

redis.get {
  key = "user:"|add:$user.id
} as user_data

Retrieves stored value
Returns null if key doesn’t exist

Has Cache Value

redis.has {
  key = ""
} as x2

Parameter	Purpose	Example
key	Cache key to check	`"session:abc"`
as	Alias for result	`x2`, `exists`

Example

redis.has {
  key = "session:"|add:$session.id
} as session_exists

Checks if key exists in cache
Returns boolean

Delete Cache Value

redis.del {
  key = ""
}

Parameter	Purpose	Example
key	Cache key to delete	`"user:123"`

Example

redis.del {
  key = "temp:"|add:$id
}

Removes key and value from cache
No effect if key doesn’t exist

Increment Cache Value

redis.incr {
  package_key = ""
  key = ""
  by = 1
} as x3

Parameter	Purpose	Example
package_key	Optional namespace	`"app1"`
key	Cache key to increment	`"counter:123"`
by	Increment amount	`1`, `5`
as	Alias for new value	`x3`, `new_count`

Example

redis.incr {
  key = "visits:"|add:$page.id
  by = 1
} as visit_count

Increments numeric value
Creates key with value 0 if doesn’t exist

Decrement Cache Value

redis.decr {
  key = ""
  by = 1
} as x4

Parameter	Purpose	Example
key	Cache key to decrement	`"stock:123"`
by	Decrement amount	`1`, `5`
as	Alias for new value	`x4`, `new_count`

Example

redis.decr {
  key = "stock:"|add:$product.id
  by = 1
} as remaining_stock

Decrements numeric value
Creates key with value 0 if doesn’t exist

Get Cache Keys

redis.keys {
  search = ""
} as keys1

Parameter	Purpose	Example
search	Pattern to match keys	`"user"`, `"session"`
as	Alias for matched keys	`keys1`, `matching_keys`

Example

redis.keys {
  search = "user"
} as active_sessions

Returns array of matching keys

Add To End of List

redis.push {
  package_key = ""
  key = ""
  value = ""
} as x5

Parameter	Purpose	Example
package_key	Optional namespace	`"app1"`, `"myservice"`
key	List key	`"queue:tasks"`, `"notifications"`
value	Value to append	`"task1"`, `{id: 123}`
as	Alias for new list length	`x5`, `list_length`

Example

redis.push {
  package_key = "notifications"
  key = "user:"|add:$user.id
  value = $new_message
} as queue_length

Adds value to end of list
Creates list if it doesn’t exist
Returns new length of list
Supports any data type for value

Add To Beginning of List

redis.unshift {
  key = ""
  value = ""
} as x6

Parameter	Purpose	Example
key	List key	`"queue:tasks"`, `"recent_items"`
value	Value to prepend	`"new_task"`, `{priority: "high"}`
as	Alias for new list length	`x6`, `list_length`

Example

redis.unshift {
  key = "recent_views"
  value = $page.id
} as list_size

Adds value to beginning of list
Creates list if it doesn’t exist
Returns new length of list
Useful for “most recent” lists

Remove From End of List

redis.pop {
  key = ""
} as x7

Parameter	Purpose	Example
key	List key	`"queue:tasks"`, `"stack:items"`
as	Alias for popped value	`x7`, `last_item`

Example

redis.pop {
  key = "task_queue"
} as next_task

Removes and returns last element
Returns null if list is empty
Reduces list length by 1
Common for stack operations

Remove From Beginning of List

redis.shift {
  key = ""
} as x8

Parameter	Purpose	Example
key	List key	`"queue:tasks"`, `"processing"`
as	Alias for shifted value	`x8`, `first_item`

Example

redis.shift {
  key = "message_queue"
} as next_message

Removes and returns first element
Returns null if list is empty
Reduces list length by 1
Common for queue operations

Remove From List

redis.remove {
  key = ""
  value = ""
  count = 0
}

Parameter	Purpose	Example
key	List key	`"active_users"`, `"blocked_ips"`
value	Value to remove	`"user123"`, `{id: 456}`
count	Number of occurrences to remove	`0` (all), `1`, `-2`

Example

redis.remove {
  key = "active_sessions"
  value = $session.id
  count = 0
}

Removes matching values from list
Count=0 removes all occurrences
Count>0 removes from head to tail
Count<0 removes from tail to head

Get Length Of List

redis.count {
  key = ""
} as x9

Parameter	Purpose	Example
key	List key	`"queue:pending"`, `"users:online"`
as	Alias for list length	`x9`, `count`

Example

redis.count {
  key = "waiting_users"
} as queue_size

Returns current length of list
Returns 0 if list doesn’t exist
Useful for queue management
Quick operation regardless of list size

Get Elements From List

redis.range {
  key = ""
  start = 0
  stop = -1
} as x10

Parameter	Purpose	Example
key	List key	`"recent:items"`, `"leaderboard"`
start	Start index	`0`, `5`, `-10`
stop	End index	`-1`, `9`, `20`
as	Alias for range values	`x10`, `items`

Example

redis.range {
  key = "recent_posts"
  start = 0
  stop = 9
} as recent_items

Returns range of list elements
-1 means last element
Supports negative indices
Inclusive of start and stop indices

Rate Limit

Example

redis.ratelimit {
  key = "ip:"|add:$request.ip
  max = 100
  ttl = 3600
  error = "Rate limit exceeded. Try again later."
} as rate_status

Implements rate limiting
Tracks attempts within time window
Returns current limit status
Throws error when limit exceeded
