I'm trying to use lettuce instead of Jedis for it's reactive pattern. Jedis can block my vertx eventloop and instead of making it a blocking operation I'd rather have it be reactive.
I can successfully fetch items from redis using lettuce but I haven't figured out how to handle exceptions. As an example-
// Attempt A: Is the error in otherstuff?redis.get(cacheKey).handle((response, otherstuff) -> { ... }).subscribe();// Attempt B: Do I add a doOnError?redis.get(cacheKey).handle((response, otherstuff) -> { ... }).doOnError((error) -> { logger.error(err); }).subscribe();// Attempt C: Do I add my callbacks to subscribe?redis.get(cacheKey).subscribe((response) -> { ... }, (err) -> { logger.error(err); });The first confusion I have is how many ways I can do the same thing. I've found multiple ways to actually get a value, but I've found no way to catch an error. The cache key it's pulling from does not exist, my assumption is that an error would be thrown somewhere.
How do I catch lettuce errors?
