A retry policy for the Spanner library based on counting errors.

This policy stops retrying if:

• An RPC returns a non-transient error.
• More than a prescribed number of transient failures is detected.

In this class the following status codes are treated as transient errors:

• kUnavailable
• kResourceExhausted
• kInternal if the error message indicates a connection reset.

Constructors

LimitedErrorCountRetryPolicy(int)

Create an instance that tolerates up to maximum_failures transient errors.

Note: Disable the retry loop by providing an instance of this policy with maximum_failures == 0.
