Transactions can be retried using the Transient Fault Handling Application Block.
This extension helps you create a strategy that will detect transient faults when performing
transactions with Spanner.
To create an execution strategy, create a class
class SpannerTransientErrorDetectionStrategy : ITransientErrorDetectionStrategy
{
public bool IsTransient(Exception ex) => ex.IsTransientSpannerFault();
}
public static bool IsTransientSpannerFault(this Exception exception)
Returns true if the exception represents a transient error in Spanner.
This indicates that the operation may succeed if it is attempted again.
Common errors that can cause this include temporary network interruption
or the service being temporarily unavailable.
