I do not understand your question. What are you trying to achieve?

At present we are using Logstash --\> MongoDB Syn for polling data.  
my question is:  
**“Which database is more reliable for Logstash polling data in terms of performance, stability, and persistent connection?”**  
is it inflexDB or MongoDB

Logstash was designed to move data from different sources into Elasticsearch, so I am not sure it is a good tool for replicating between any other set of databases.

The question seems a bit backwards. Usually you have different datastores between you wish to sync data and select a tool/method based on that, not the other way around.

Thanks for quick response 🙂  
I have gone through so many links but there is no such link explain  
which DB is more reliable for Logstash fetching data and processing into Elasticsearch--Kibana  
But i need more pro and Cons above question .  
“Much appreciated if anybody can suggest.”

I do not think I would use Logstash for replicating data from either of those databases as I am not sure the input plugins are capable enough (have not used them). I have seen it work well replicating data from RMDBS via JDBC but that is it.
