When I started writing pg_chameleon I had in mind a tool making simple to migrate from different dbms engines to PostgreSQL. The name was inspired by the Culture Club’s Karma chameleon song which suggested me the idea of a tool capable to move data between different database technologies. Then tool’s scope changed becoming a replica system rather a migration system but I’ve kept the name as I think the idea is still valid.
Today is one year since I started working seriously on pg_chameleon. With this commit I changed the project’s license to the 2 clause BSD and the project’s scope, evolving the project into a MySQL to PostgreSQL replica system. Initially this change was just a try. I needed to synchronise the data between MySQL and PostgreSQL and at that time the only option I had it was to use the MySQL foreign data wrapper, eventually to copy the data locally every now and then.
Last 30th of May I had the honor to talk at the second Estonia PostgreSQL User Group. My talk was about my pet project pg_chameleon and it went very well. The audience was about 40 people highly interested in the topic and the questions were all around. I’m impressed by the Estonian PostgreSQL User Group. Their organizational skills are amazing, the members interest is very high and they are fantastic friends.
