Are connections pooled or not? Konrad Garus digs to find the answer:
Easy. Too easy and comfortable. Coming from the old good and heavy JDBC/SQL I felt uneasy with the connection management. How does it work? Does it just open a connection and leave it dangling in the air the whole time? Might be good for a quick spike in REPL, but not for a real application which needs concurrency, is supposed to be running for days and weeks, and so on. How do you maintain it properly?
