> When you select on *PutDistributedMapCache CACHE_UPDATE_STRATEGY = CACHE_UPDATE_REPLACE we execute "cache.put(cacheKey, cacheValue, keySerializer, valueSerializer);"* [LINK|https://github.com/apache/nifi/blob/ea9b0db2f620526c8dd0db595cf8b44c3ef835be/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/main/java/org/apache/nifi/processors/standard/PutDistributedMapCache.java#L202]
> If you use redis as backend service this jumps to: RedisDistributedMapCacheClientService.java -> redisConnection.set(kv.getKey(), kv.getValue(), Expiration.seconds(ttl), null); [LINK|https://github.com/apache/nifi/blob/ea9b0db2f620526c8dd0db595cf8b44c3ef835be/nifi-nar-bundles/nifi-redis-bundle/nifi-redis-extensions/src/main/java/org/apache/nifi/redis/service/RedisDistributedMapCacheClientService.java#L191]
> Calling to spring-data/redis/ library, but we have a bug putting null as Option parameter, causing an error "option cannot be null", because according to library: "{{option}} - must not be null."

> If we want to update strategy we should use: [{{RedisStringCommands.SetOption.upsert()}}|https://docs.spring.io/spring-data/redis/docs/current/api/org/springframework/data/redis/connection/RedisStringCommands.SetOption.html#upsert--]
