How to set Activity Retry Options in Java

To set a Retry Policy, known as the Retry Options in Java, use ActivityOptions.newBuilder.setRetryOptions().

• Type: RetryOptions

• Default: Server-defined Activity Retry policy.

• With ActivityStub

  private final ActivityOptions options =
      ActivityOptions.newBuilder()
          // note that either StartToCloseTimeout or ScheduleToCloseTimeout are
          // required when setting Activity options.
          .setStartToCloseTimeout(Duration.ofSeconds(5))
          .setRetryOptions(
              RetryOptions.newBuilder()
                  .setInitialInterval(Duration.ofSeconds(1))
                  .setMaximumInterval(Duration.ofSeconds(10))
                  .build())
          .build();

• With WorkflowImplementationOptions

  WorkflowImplementationOptions options =
          WorkflowImplementationOptions.newBuilder()
                 .setActivityOptions(
                      ImmutableMap.of(
                          "EmailCustomerGreeting",
                          ActivityOptions.newBuilder()
                                // note that either StartToCloseTimeout or ScheduleToCloseTimeout are
                                // required when setting Activity options.
                                .setStartToCloseTimeout(Duration.ofSeconds(5))
                                .setRetryOptions(
                                      RetryOptions.newBuilder()
                                          .setDoNotRetry(NullPointerException.class.getName())
                                          .build())
                                .build()))
                .build();
