Hello,

For the last few hours i have been trying to implement synchronisation between MySQL database and Elasticsearch using Logstash and the JDBC plugin.  
Each row in each table has a updated\_at column (timestamp, refreshed when something changes in the row), created\_at column (timestamp, only set when the row is created) and a deleted column (boolean, set to true when the backend - play framework - deletes something, no hard deletes).  
What i want to do is _ **query all rows from all tables that have been updated / created** _ since the last check, and _ **add** _ those that have been just created (_created\_at \> last check_), _ **update** _ existing documents (_updated\_at \> last check_) and _ **delete** _ those that have their deleted flag set to true and _updated\_at \> last check_.  
Im having a real trouble figuring out how to do this and any help, links or pointers would be appreciated 🙂

PS: If i understand correctly each table should have its own index, right? All examples on the internet only check one table 😕

Is the updated\_at column set for newly created documents, i.e. do you actually need to care about created\_at?
