sorted_set

Category: Collections
Wire type: sorted_set
Construction: CREATE

Collections are synchronized mutable structures manipulated with OP.

Create a value

Use the top-level CREATE command to initialize this structured value. The example shows its construction options.

amaquet-cli -uri amaquet://127.0.0.1:13378 CREATE '{"key":"example:sorted_set","type":"sorted_set","options":{}}'

Construction options

Example CREATE options: {}. Omitted fields use server defaults.

Supported operations

ADD, REMOVE, SCORE, RANGE.

See the complete operation contract for exact arguments, defaults, results, and whether a listed GET is the top-level key command or a type-specific OP. It also identifies read-only operations and documents validation, lazy maintenance, and key-version behavior.

Operation payloads

The following examples use the public amaquet-cli JSON command format. Replace example:sorted_set with the key used by your application.

Construction payloads

Use the payload below to initialize this type before issuing reads or type-specific operations.

CREATE

This payload initializes the value and must complete before its type-specific operations are used.

{
  "key": "example:sorted_set",
  "type": "sorted_set",
  "options": {}
}

Operations

Each request uses the OP envelope. The response is the type-specific value described in the complete operation contract.

OP ADD

Accepts nested member, numeric score and returns true if new, false if score replaced.

{
  "key": "example:sorted_set",
  "operation": "ADD",
  "args": {
    "member": {
      "type": "utf8_string",
      "value": "alpha"
    },
    "score": 10.5
  }
}

OP SCORE

Accepts nested member and returns the member score or null when absent.

{
  "key": "example:sorted_set",
  "operation": "SCORE",
  "args": {
    "member": {
      "type": "utf8_string",
      "value": "alpha"
    }
  }
}

OP REMOVE

Accepts nested member and returns whether it was removed.

{
  "key": "example:sorted_set",
  "operation": "REMOVE",
  "args": {
    "member": {
      "type": "utf8_string",
      "value": "alpha"
    }
  }
}

OP RANGE

Accepts optional inclusive start, stop, and reverse and returns score-ordered entries.

{
  "key": "example:sorted_set",
  "operation": "RANGE",
  "args": {
    "start": 0,
    "stop": -1,
    "reverse": false
  }
}

Top-level read payload

GET reads the current value without changing it:

{
  "key": "example:sorted_set"
}

Key lifecycle payloads

These commands apply to the key regardless of its registered type:

• TYPE: {"key":"example:sorted_set"} — returns the wire type.
• EXISTS: {"key":"example:sorted_set"} — reports whether the key exists.
• EXPIRE: {"key":"example:sorted_set","ttl_ms":5000} — assigns a five-second TTL.
• TTL: {"key":"example:sorted_set"} — returns the remaining TTL in milliseconds.
• PERSIST: {"key":"example:sorted_set"} — removes the TTL.
• DEL: {"keys":["example:sorted_set"]} — deletes the key.

For defaults, validation, result shapes, and persistence classification, see the complete operation contract.

Key lifecycle

The key participates in TYPE, EXISTS, TTL, EXPIRE, PERSIST, and DEL. Top-level GET returns the type’s direct public value or a synchronized snapshot.
