The options arguments can contain the following option properties:

PropertyType (default)Description
limit
integer[2]
An array of 2 integers, used to limit the number of returned matching elements (similar to SELECT LIMIT offset, count in SQL).
Format: [<offset>,<count>]
queuable
boolean (true)
If true, queues the request during downtime, until connected to Kuzzle again
timeout
number

(-1)
Time (in ms) during which a request will still be waited to be resolved. Set it -1 if you want to wait indefinitely
triggerEvents
boolean

(false)
If set to true, will trigger events even if using Embeded SDK. You should always ensure that your events/pipes does not create an infinite loop.
Available since Kuzzle 2.31.0

Resolve #

Resolves to an array of matched elements.

Usage #

try {
  await kuzzle.ms.zadd('ssetfoo', [
    {member: 'foo', score: '0'},
    {member: 'bar', score: '0'},
    {member: 'baz', score: '0'}
  ]);
  // Prints: [ 'baz', 'bar' ]
  // Lexicographically gets elements with a maximum value of 'f' (excluded),
  // without a minimum value
  console.log(await kuzzle.ms.zrevrangebylex('ssetfoo', '-', '(f'));
} catch (error) {
  console.error(error.message);
}
