I've endured Datomic for 4 years and I really wonder what the folks who enjoy it are doing, because for me it us utter misery.
- It's miserably slow (if you wish to contradict this statement, please provide numbers)
- Consumes gobs of memory (export our data to JSON and it's orders of magnitude smaller)
- Full text search will consume all your CPU cores for if you given it a short query (seriously, don't touch this feature, it is a basket full of footguns)
- Resource leaks (the Cassandra backend used to leak full databases!)
I've been up to 3:00 a.m. dealing with bugs in Datomic. What use cases does it actually work for?
