Class RetryStrategy

Represents a retry strategy that determines how many times should be retried and the interval between retries.

Inheritance

System.Object

Namespace: Umbraco.Cms.Infrastructure.Persistence.FaultHandling

Assembly: Umbraco.Infrastructure.dll

Syntax

public abstract class RetryStrategy

Constructors

RetryStrategy(String, Boolean)

Initializes a new instance of the RetryStrategy class.

Declaration

protected RetryStrategy(string name, bool firstFastRetry)

Parameters

Type	Name	Description
System.String	name	The name of the retry strategy.
System.Boolean	firstFastRetry	a value indicating whether or not the very first retry attempt will be made immediately whereas the subsequent retries will remain subject to retry interval.

Fields

DefaultClientBackoff

The default amount of time used when calculating a random delta in the exponential delay between retries.

Declaration

public static readonly TimeSpan DefaultClientBackoff

Field Value

Type	Description
TimeSpan

DefaultClientRetryCount

The default number of retry attempts.

Declaration

public static readonly int DefaultClientRetryCount

Field Value

Type	Description
System.Int32

DefaultExponential

Returns a default policy that implements a random exponential retry interval configured with DefaultClientRetryCount, DefaultMinBackoff, DefaultMaxBackoff and DefaultClientBackoff parameters. The default retry policy treats all caught exceptions as transient errors.

Declaration

public static readonly RetryStrategy DefaultExponential

Field Value

Type	Description
RetryStrategy

DefaultFirstFastRetry

The default flag indicating whether or not the very first retry attempt will be made immediately whereas the subsequent retries will remain subject to retry interval.

Declaration

public static readonly bool DefaultFirstFastRetry

Field Value

Type	Description
System.Boolean

DefaultFixed

Returns a default policy that implements a fixed retry interval configured with DefaultClientRetryCount and DefaultRetryInterval parameters. The default retry policy treats all caught exceptions as transient errors.

Declaration

public static readonly RetryStrategy DefaultFixed

Field Value

Type	Description
RetryStrategy

DefaultMaxBackoff

The default maximum amount of time used when calculating the exponential delay between retries.

Declaration

public static readonly TimeSpan DefaultMaxBackoff

Field Value

Type	Description
TimeSpan

DefaultMinBackoff

The default minimum amount of time used when calculating the exponential delay between retries.

Declaration

public static readonly TimeSpan DefaultMinBackoff

Field Value

Type	Description
TimeSpan

DefaultProgressive

Returns a default policy that implements a progressive retry interval configured with DefaultClientRetryCount, DefaultRetryInterval and DefaultRetryIncrement parameters. The default retry policy treats all caught exceptions as transient errors.

Declaration

public static readonly RetryStrategy DefaultProgressive

Field Value

Type	Description
RetryStrategy

DefaultRetryIncrement

The default amount of time defining a time increment between retry attempts in the progressive delay policy.

Declaration

public static readonly TimeSpan DefaultRetryIncrement

Field Value

Type	Description
TimeSpan

DefaultRetryInterval

The default amount of time defining an interval between retries.

Declaration

public static readonly TimeSpan DefaultRetryInterval

Field Value

Type	Description
TimeSpan

NoRetry

Returns a default policy that does no retries, it just invokes action exactly once.

Declaration

public static readonly RetryStrategy NoRetry

Field Value

Type	Description
RetryStrategy

Properties

FastFirstRetry

Gets or sets a value indicating whether or not the very first retry attempt will be made immediately whereas the subsequent retries will remain subject to retry interval.

Declaration

public bool FastFirstRetry { get; set; }

Property Value

Type	Description
System.Boolean

Name

Gets the name of the retry strategy.

Declaration

public string Name { get; }

Property Value

Type	Description
System.String

Methods

GetShouldRetry()

Returns the corresponding ShouldRetry delegate.

Declaration

public abstract ShouldRetry GetShouldRetry()

Returns

Type	Description
ShouldRetry	The ShouldRetry delegate.
