module:queue. RedisClient
Queue client based on Redis server using https://github.com/NodeRedis/node_redis3
The queue client implements reliable queue using sorted sets, one for the new messages and one for the messages that are being processed if timeout is provided. With the timeout this queue works similar to AWS SQS.
The interval config property defines in ms how often to check for new messages after processing a message, i.e. after a messages processed
it can poll immediately or after this amount of time
The retryInterval config property defines in ms how often to check for new messages after an error or no data, i.e. on empty
pool when no messages are processed it can poll immediately or after this amount of time
The visibilityTimeout property specifies to use a shadow queue where all messages that are being processed are stored,
while the message is processed the timestamp will be updated so the message stays in the queue, if a worker exists or crashes without
confirming the message finished it will be put back into the work queue after visibilityTimeout milliseconds. The queue name that
keeps active messages is appended with #.
Protocol rediss: will use TLS to connect to Redis servers, this is required for RedisCche Serverless
The threshold property defines the upper limit of how many active messages can be in the queue when to show an error message, this is
for monitoring queue performance
