Hi Eric Well, there is no official statement besides the one you have quoted below, but anyone in the Galaxy team I have spoken to recently told me to move to PostgreSQL. And that's why, I've been through the painful process of migrating our MySQL database to a PostgreSQl database. Actually, the switch for our production server just happened this morning - and I am still anxious whether I have done everything correctly. Our system admin also prefers MySQl. Hence I had to set up my own PostgreSQL server. And now, I am running the back-ups myself. For your case: why not moving the Galaxy server to the "new more powerful environment" but still connected to the old PostgreSQL server? I don't think the database server (unless it is sqlite) is ever the bottleneck, is-it? Regards, Hans-Rudolf On 07/27/2015 02:35 PM, Eric Kuyt wrote:
Hi All,
We are thinking of putting our galaxy instance in a new more powerful environment. Galaxy is now on a single server containing a psql database which is migrated from mysql a few years ago. The new environment already houses a really nice backupped highly available mysql server.
as galaxy admin I am quite reluctant of migrating back to mysql, the system admin is quite reluctant of installing this psql database with the same grade of backup and availability just for galaxy.
I could only come up with the line "/PostgreSQL is much preferred since we've found it works better with our DB abstraction layer, SQLAlchemy <http://www.sqlalchemy.org/>./" from the galaxy wiki, which is a rather slim argument.
My question now is.
Is Postgres still the preferred database or is Mysql now also a safe bet.
For mysql we would have to migrate back, system management would have a lot of experience tuning databases and a high quality instance is already running.
For Psql a new database instance would have to be installed, less knowledge of the database system is available but it is the preferred database.
Could someone point out some more pros and cons in this question?
Thanks,
Eric
