Thread: open-source equivalent of golden-gate

open-source equivalent of golden-gate

Hi

In the Oracle world we use the product "golden gate" to execute transactions from a source database (Oracle, Mysql) to a PostgreSQL instance.

This allows 2 Oracle and PostgreSQL databases to be updated at the same time in real time.

I would like to know if there is an equivalent open-source product.

 

Thanks in advance

 

Best Regards

There is a SQL/MED standard exactly for this: https://wiki.postgresql.org/wiki/SQL/MED

Implemented in PostgreSQL as Foreign Data Wrappers: https://wiki.postgresql.org/wiki/Fdw
You need to do the following:
1. Add wrapper via https://www.postgresql.org/docs/current/sql-createextension.html
2. Create remote source via https://www.postgresql.org/docs/current/sql-createserver.html
3. Create foreign table via https://www.postgresql.org/docs/current/sql-createforeigntable.html

Note, that PostgreSQL provides only infrastructure, wrappers for different remote systems are not supported by the PostgreSQL community,
except for postgres_fdw and csv_fdw provided by the project.

I read the question as perhaps concerning the other direction, whether
there might be an open source foreign data wrapper installable in Oracle
for talking to PostgreSQL (which might, I suppose, also have a name like
"postgres_fdw", which helps explain the number of times I've rewritten
this sentence trying to make it unambiguous).

The closest solutions to golden gate are probably

Oracle Database Gateway for ODBC can be used:
