I'm new to elastic search and evaluating a need to synchronize data from relational database to elastic search.
This article provided a solution to achieve it - [https://www.elastic.co/blog/how-to-keep-elasticsearch-synchronized-with-a-relational-database-using-logstash](https://www.elastic.co/blog/how-to-keep-elasticsearch-synchronized-with-a-relational-database-using-logstash)
This solution seem attractive to me as its low level and avoid writing explicit code to synchronize data in elastic search.
I have few questions though:
Can logstash handle failures like elastic search being down for some reason & guarantee delivery atleast once on such scenarios when its back up ?
Whats the best way to monitor such process to ensure its synchronizing ? Appreciate to any pointers on best practices or documentation.
