Properties
$disableIndex
You can disable the use-index-for-collect optimization for individual COLLECT operations by setting this option to true.
public
bool
$disableIndex
COLLECT ... OPTIONS { disableIndex: true }
The optimization improves the scanning for distinct values using COLLECT if a usable persistent index is present.
It is automatically disabled if the selectivity is high, i.e. there are many different values,
or if there is filtering or an INTO or AGGREGATE clause.
Tags
$method
There are two variants of COLLECT that the optimizer can choose from: the sorted and the hash variant.
public
string|null
$method
The method option can be used in a COLLECT statement to inform the optimizer about the preferred method, "sorted" or "hash".
Methods
__construct()
Creates a new QueryOptions instance.
public
__construct([array<string|int, mixed>|object|null $init = null ]) : mixed
Parameters
- $init : array<string|int, mixed>|object|null = null
-
A generic object containing properties with which to populate the newly instance. If this argument is null, it is ignored.
jsonSerialize()
Invoked to serialize the object with the json serializer.
public
jsonSerialize() : array<string|int, mixed>
