I don't want to change my code to write into C* and then to ES. So, I'm looking for some sort of a sync tool that will sync my C* table into ES and it should be smart enough to avoid duplicates or gaps. Is there such a tool / plugin ? I'm using stock apache Cassandra 3.7. I know that some premium Cassandra has ES builtin or integrated but I can't afford premium right now... Thanks.
