AdaptiveCache
class AdaptiveCache (View source)
Properties
| bool read-only | $enabled | Whether the adaptive cache is enabled for this Relay object. |
|
| string read-only | $status | The actual state of the adaptive cache. The user can request an adaptive cache of a certain width and depth, but it is not actually created until Relay attaches to an in-memory endpoint. This can fail if we are out of memory. This property will be ['inactive', 'active']. |
|
| int read-only | $width | The underlying count-min sketch width. |
|
| int read-only | $depth | The underlying count-min sketch depth. |
|
| int read-only | $minEvents | Minimum number of events before a key is cached. |
|
| float read-only | $minRatio | Minimum read/write ratio before a key is cached. |
|
| string read-only | $formula | The adaptive cache formula ( |
