Is there a limit on number of redis servers a logstash can read from?

My usecase is, we have client servers which stores events data in redis. We would like to store these centrally in the elastic search and analyse the log data.

What is the limit on the number of external redis servers a logstash can read from?
Is there any limit on how many hosts i can specify in the redis input section in the logstash config file??

Thanks,

I don't think there is any sort of limits.
