zcount #

Returns the number of elements held by a sorted set with a score within the provided range.

Arguments #

zcount(key, min, max, [options]);

Arguments	Type	Description
`key`	string	Sorted set key
`min`	string	Minimum range value
`max`	string	Maximum range value
`options`	object	Optional query arguments

By default, the provided min and max values are inclusive. This behavior can be changed using the syntax described in the Redis ZRANGEBYSCORE documentation.

options #

The options arguments can contain the following option properties:

Property	Type (default)	Description
`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

Usage #

try {
  await kuzzle.ms.zadd('ssetfoo', [
    {member: 'foo', score: '42'},
    {member: 'bar', score: '4'},
    {member: 'baz', score: '-272.15'}
  ]);
  // Prints: 2
  // Counts elements with a score lower than 42 (excluded)
  console.log(await kuzzle.ms.zcount('ssetfoo', '-inf', '(42'));
} catch (error) {
  console.error(error.message);
}
