I am going to sync a schema in postgres with one in an oracle db. The
tables are simple, but there are 200 of them. I would like to try to
keep the sync lag < 1 minute. Here is my idea. Please critique/suggest.
1. Set up stored proc on oracle that records a INSERT, UPDATE, DELETE
SQL action taken on a table into a log table.
2. Program reads the log table on oracle and issues the same SQL command
on the postgres db. In the same transaction, postgres writes to a log
showing the command has been executed.
3. The program will query the oracle log table on some frequency ~30
seconds.
What are your thoughts?
