pg_chameleon v2.0.0.alpha2 is out

Has been a while since I wrote a post on this blog. I’ve been quite busy on coding pgchameleon’s version 2. I finally managed to release an alpha1 the 11th of November but this release had several issues which prevented the users to have real tests. However, after a week of debugging I’ve released pg_chameleon v2.0.0.alpha2 which is now quite usable. For a complete command line reference and an usage example click here.

Happy birthday pg_chameleon

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.

pg_chameleon 1.3 out

Bugfix emergency release v1.3.1 I discovered a regression when running the init_replica caused by a wrong handling of missing time in master coordinates. Sorry about that. After another round of bug fixes I’ve released the version 1.3 of my pet project pg_chameleon. The package is available on pypi as usual. The changelog is available here. If you have any question/issue to discussI created a community on gitter. Please join!

pg_chameleon v1.1 out

Last week I announced the stable release of pg_chameleon as I felt quite confident the tool worked properly. However the murphy law is always ready to teach us we live in an interesting universe. A couple of days after the release I noticed on a server which data were modified seldom a strange replica issue. For some reason at specific moments of the day the inserts replayed on the postgres tables failed with the primary key violation.

pg_chameleon 1.0 RC1 available now

In 2013 I started my pet project pg_chameleon to discharge my frustration only to find the entire thing even more frustrating. It’s fascinating how time and circumstances can fix the personal perspective revamping the passion for development that never left me. This philosophical introduction is to tell I still can’t believe I’ve relased the RC1 of my pet project pg_chameleon. The release is already available on pypi and includes several bug fixes and performance improvement.
