LinearRetry

Constructor

LinearRetry(backoff: int = 15, retry_total: int = 3, retry_to_secondary: bool = False, random_jitter_range: int = 3, **kwargs: Any)

Parameters

Name Description
backoff
int

The backoff interval, in seconds, between retries.

Default value: 15
retry_total
int

The maximum number of retry attempts.

Default value: 3
retry_to_secondary
bool

Whether the request should be retried to secondary, if able. This should only be enabled of RA-GRS accounts are used and potentially stale data can be handled.

Default value: False
random_jitter_range
int

A number in seconds which indicates a range to jitter/randomize for the back-off interval. For example, a random_jitter_range of 3 results in the back-off interval x to vary between x+3 and x-3.

Default value: 3
