This Week in Data With Colin Charles 51: Debates Emerging on the Relicensing of OSS

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

There has been a lot of talk around licenses in open source software, and it has hit the database world in the past weeks. Redis Labs relicensed some AGPL software to the Commons Clause (in their case, Apache + Commons Clause; so you can’t really call it Apache any longer). I’ll have more to say on this topic soon, but in the meantime you might enjoy reading Open-source licensing war: Commons Clause. This was the most balanced article I read about this move and the kerfuffle it has caused. We also saw this with Lerna (not database related), and here’s another good read: …

PostgreSQL Accessing MySQL as a Data Source Using mysql_fdw

There are many organizations where front/web-facing applications use MySQL and back end processing uses PostgreSQL®. Any system integration between these applications generally involves the replication—or duplication—of data from system to system. We recently blogged about pg_chameleon which can be used replicate data from MySQL® to PostgreSQL. mysql_fdw can play a key role in eliminating the problem of replicating/duplicating data. In order to eliminate maintaining the same data physically in both postgres and MySQL, we can use mysql_fdw. This allows PostgreSQL to access MySQL tables and to use them as if they are local tables in PostgreSQL. mysql_fdw can be used, too, with …
