Preferable database for JIRA/Confluence

Please propose the best database engine for running a JIRA/Confluence instance.

I found an issue here:

At the bottom, Charles Miller wrote that the best solution is the one for which we have experience.

It's quite old post so do you still stand by this opinion?

Maybe from your experience with different customers, you recommend specific engine?

We are considering MSSQL and PostgreSQL. Do you know any advantages/disadvantages between them?

Thank you

Atlassian recommend PostGreSQL first and MySQL second.

I'd never recommend MSSQL over those two, or even Oracle to be frank, especially for java based tools. I've never had database problems with Post or My with Atlassian products, but MSSQL has turned out to be an absolutely monumental pain in the neck, repeatedly.

However, Charles' advice is good. My experience is based on not really having DBA expertise on hand. You may need it if you use MSSQL. You almost certainly won't need it for day-to-day usage if you use Post or My (barring doing the standard backups/failover stuff). If you have expert MSSQL people on hand, and you are comfortable with MSSQL, and not with the others, then use it.

Hi Michal,

There are some advantages and disadvantages for both engine. However just give you some idea, we use PostgreSQL for our OnDemand platform.

Hope it helps.

I'd agree with Nic and take PostgreSQL & Oracle over MS-SQL. If MS-SQL is what you know then it can work but don't ever be tempted to use the MS JDBC drivers. Atlassian warn you off them for a reason. Unfortunately, it means you loose the ability to do any kind of failover but that 0.1% of uptime wasn't worth the 99.9% of degraded performance.

Go with your strengths and if you know PostgreSQL then your question has been answered!

Hello Michael,

Just in addition to the previous answers, we also use PostgreSQL and MySQL in the most of the times in our test instances without any problem, both DBs are recommended.



We've used Jira and Confluence on Oracle for years without any problem.

The other question is whether you want to run on Linux or Windows. It also depends on what skills you have in your business to run the infrastructure.

We've used SQL Server and it's a pain in the A***, actually it's unusable with JIRA.

What's the problem with SQL server?

It's poorly supported by MS as well - when I first ran into problems with it, MS support told us to try their drivers instead of the jtds ones. The MS drivers do not work - they feel like they haven't been tested, just thrown out there to pretend that MS supports java.

That said, it can work fine. It does work fine in a lot of cases. But don't bet on it.

SQL Server frequently DEADLOCKs and SQL Server is poorly supported by Atlassian.

We are using MS SQL Server for both Jira and Confluence without any problems.

Do we have a hierarchy? I know PostGre is the one recommended by Atlassian. Out of Oracle and SQL Server, which one would you recommend the most?

Oracle. The answers here haven't changed in the last 3 years. The preferred order is very much Postgres first, MySQL a close second, Oracle third, and Microsoft in a very distant fourth place. The only time I'd recommend MS-SQL is when your organisation has no support expertise for the others.

True, MS SqlServer is the worst, deadlocks everywhere and badly supported. The only officially supported jtds driver is old as the hills.

Yes, it's very poorly supported by Microsoft - they can't even get their own drivers to work, let alone support other drivers.

Yes, MS does a terrible job here, but Atlassian could also do better. The only officially supported JTDS driver is 8 years old (v1.2.2). The current JTDS driver is from 2013 (v1.3.1).

Pretty much in line with the releases of SQL Server - they're hampered by MS and JTDS, not their own code.

MSSQL in itself runs fine, however the support and testing from Atlassian could be improved. Look at this

Yes, that's a bug on the Atlassian side. But the fact that Microsoft's own drivers are unusable is the rather telling point here. The advice still stands - you should prefer the use one of the better databases unless you have no support for them in your organisation.

I have been using Oracle DB for quite sometime now - It's been a smooth DB with a lot activities going in JIRA and CONFLUENCE of my project everyday.

TLDR; If you can afford it: Train a db admin on postgres and use postgres. Otherwise live with the problems that you have with the other databases. I have a horrible confluence upgrade. Atassians requires you to use very specific settings for MSSQL and our DB used with confluence did not comply to them. So no in place upgrade. XML Export, new DB on th cluster and then import, then update. turned out this did not work, update failed on db checks. In the end, and with atlassian support approving it, we did it this way: xml export, change DB to Porstgres, do update, xml export change db back to MSSQL do import.... And now I fear the next update... Using MSSQL because no postgres admin available. But missing the speed and the ease that postgres gave me for updating the company wiki.

I'd still swap to postures. Sounds like MS is not working for you.

Please tell us how you use Confluence space settings

👋 Hi there, a few of us at Atlassian would love to learn about how you use "space settings" functionality in Confluence. A facelift to the space settings is long overdue and we want to start with im...
