> No ETLs This seems to be listed as a feature, which I find confusing. Not everything lives in SQL databases. Some things you extract for example from external APIs. Is this basically "this is out of scope for the project", or it's a feature because we've got ?

It does say in the description that this was built for “SQL lovers.”

Hi dude,are you a hacker? Can you do me a favor to break into a illegal web in china(it's a web of bitcoin trade,but it's forbidden by Chinese government). It's a very simple job to a professional man. Contact me: xuechs@gmail.com. I wish your reply , and get money together.

BI = Writing reports

Generating reports!

BI = dashboards that are clicked through by consultants to manually generate reports that are read by management 5m every day while they take their morning shits

Don't agree, in the past metabase was good, now it's just getting worse. I was a big fan of metabase (to the point I deployed it in 4 companies and rolled it out for many people to use in their daily workflow). All was nice. Somewhere around 0.31 something changed in the internal dev/release flow. I get the feeling they have some kind of internal push to add unnecessary untested features which all look nice on paper,…

I'm on the Metabase team - We've walked a fine line between fixing bugs, adding the features that our users have asked for and building out the BI interface we think the world should be using in 5 years. We don't always get it right, and I'm sorry if we broke things for you on the performance side. We will be spending a few of our development cycles after 0.33 to try to clear out our bug queue. One specific factual p…

I’ve been using Metabase off and on in prod since 2016. I think you guys are really onto something and I love seeing Clojure in a popular OSS project. I know you guys just got some money; here’s my pitch to make it count: Metabase would be a lot more sticky if you provided a robust home for annotation and discussion. You’re better than most at letting admins describe data, but often users want to talk about the data they are discovering. Doing so in the context of the data is so much more effective than talking about it in generalities in Slack. I think Yellowfin has some features around discussion but there is always room for improvement. Maybe one could: Comment on a data point, write an explanation for why a date range has weird data, or tag a colleague to ask about an outlier in their dept. Celebrate wins with emojis? All I know is that there is nothing stickier or more engaging than discussion history. Keep up the good fight!

While I have you here... bump for the Athena driver. Also I can’t use Metabot without some privacy settings. Can’t anything be done?

What's wrong with pie charts? What would you suggest using when you want to see a percentage breakdown?

Use bars showing percentage. This way you can compare the values to a scale on the side and to each other. You can't see a difference easily on a pie chart without annotation. With enough values, you likely can't tell 5% from 10%, and difference between a fragment on the left from a fragment on the right. This is even worse in 3d pie chart which doesn't even preserve proportions in areas/angles, so splitting in 4 par…

I think it's better to say that "for most people there is a better alternative" than to say that pie charts should never be used.

EDIT: If you are showing who ate which parts of a pizza (to be pedantic) I'm sure a pie chart may be the best case solution. My favourite use of pie charts is to compare the harmonic series and the series 1/x^2, but then again this latter example is not really a traditional pie chart.

Nice project, congrats on shipping.

I’ve taken a quick glance and looked at the code. It’s a Java/Spring Boot project which usually gets a lot of flak around here for “too much magic”.

This project is written in a very clean style and seems to use a minimum of Spring. Mainly rest controllers, configuration and and dependency injection. No hibernate/orm or AOP stuff.

Pie charts are not about the raw numbers, they are about quickly and roughly showing who ate how much of the pizza. In many pie charts, 5% and 10% looking similar is a benefit, not a problem (because in many cases 5/10% are effectively the same - minor but non-negligible portions). Bar charts are not a great option for this.
