Properties
AsExternalParameter
Allows to get/set options as external parameters
Declaration
public object AsExternalParameter { get; set; }
Property Value
| Type |
Description |
| System.Object |
|
CollisionMode
Defines how table handles collisions.
Note: this property can only be supplied to table ctor, the changes are ignored after the table has created
Declaration
[Config(Default = CollisionMode.Speculative)]
public CollisionMode CollisionMode { get; set; }
Property Value
DefaultMaxAgeSec
Specifies default max age length which is applied to cache items if Put() does not specify particular max age
Declaration
[Config]
public int DefaultMaxAgeSec { get; set; }
Property Value
| Type |
Description |
| System.Int32 |
|
DetailedInstrumentation
True to include instrumentation details per table
Declaration
[Config]
public bool DetailedInstrumentation { get; set; }
Property Value
| Type |
Description |
| System.Boolean |
|
GrowthFactor
Defines the factor of growth - how much does a table grow when HWM is reached. The number has to be at least 1.2d
Declaration
[Config]
public double GrowthFactor { get; set; }
Property Value
| Type |
Description |
| System.Double |
|
InitialCapacity
How many elements an empty table should contain. The value is dependent on bucket count, so the actual table capacity is bucket-dependent
Declaration
[Config]
public long InitialCapacity { get; set; }
Property Value
| Type |
Description |
| System.Int64 |
|
LoadFactorHWM
Defines the load factor above which the growth is triggered
Declaration
[Config]
public double LoadFactorHWM { get; set; }
Property Value
| Type |
Description |
| System.Double |
|
LoadFactorLWM
Defines the load factor below which the shrinking is triggered
Declaration
[Config]
public double LoadFactorLWM { get; set; }
Property Value
| Type |
Description |
| System.Double |
|
MaximumCapacity
How many elements a table may have at maximum, the property is checked at growth.
Zero = no limit
Declaration
[Config]
public long MaximumCapacity { get; set; }
Property Value
| Type |
Description |
| System.Int64 |
|
MinimumCapacity
How many elements a table may have at minimum, the property is checked at shrinking.
Zero = no limit.
The value is dependent on bucket count, so the actual table capacity is bucket-dependent
Declaration
[Config]
public long MinimumCapacity { get; set; }
Property Value
| Type |
Description |
| System.Int64 |
|
Name
Declaration
public string Name { get; }
Property Value
| Type |
Description |
| System.String |
|
ShrinkFactor
Defines the factor of shrinking - how much does a table shrink when LWM is reached. The number has to be at most 0.7d
Declaration
[Config]
public double ShrinkFactor { get; set; }
Property Value
| Type |
Description |
| System.Double |
