A comment to ".. mysql replication to heterogeneous database".  Isn't a slave of a multi-master MySQL replication setup (what I understand is possible with GTIDs at least) a 'heterogeneous database' as well?

I can only agree that the new discovery/technology that justifies (if it does) a patent grant is not easy to see. And terms used in the document are not all well-defined either IMO. 

Besides much of the document is just a rewrite/quote of MySQL documentation (such as http://dev.mysql.com/doc/refman/5.5/en/data-types.html for instance).

Hi,

After a short read, it seems that they use a new technology called VAM (Vendor Access Module) to process binlog files/events and extract module (e.g. Oracle GoldenGate) to create trail that is then applied to target database (e.g. Non-MySQL database). It is strange that they got this patent with that badly done background literature review. Thus they trye to patent mysql replication to heterogeneous databases. These patents are very hard to read because actual invention is buried to legal text.

I occasionally found this in a Google search:

What does this mean? Are anybody able to explain what the patent covers that has not been used in MySQL replication for 10+ years before the patent?  Does this mean any restrictions for utilizing binary log information in applications?
