How can we import only new/updated records if there is no unique/timestamp in sql server (using logstash)

Dear All.

i have some data in sql server side but there is no any unique records there but
we want to import only newly / updated data from sql server to elastic search as index .

please help for this use case.


You need to be able to write a query that at any point extracts only new records. This generally requires a time stamp or sequence number, so without that I think it will be hard.
