Hi all
I have an application that reads the contents of a few tables every 2 hours.
If no new records have been added, and if no updates to existing records
have been made in the last 2 hours, the app does nothing.
If some records have been updated or added, the app does some work, and
marks the record as processed.
Currently anyone updating a record is expected to mark it manually as
needing processing. Otherwise the application doesn't know.
Is there a better, more user friendly way, for the app to automatically find
out which records have been updated. Maybe a column that has a time field
that Postgres can update to "now" each time an update is made?
Thanks
PVS
