My experience with Alation has been good and best. It helped us to get a better visibility into our data, it made our team to undestand better whenever they needed. it works best when comes to data discovery and collaboration . It take sometime in the earlly used and later it gets better when everyone comfortable with it. but when its adopted our usage become more comfortable and smoothly to adding value to our day-to-day works.

Alation did not work well with starburst connector, but apart from that its a nice tool with good data discovery features and good query editor.
