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:

http://www.google.nl/patents/US8510270

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?
