It is very easy to set up with minimal configuration required from our side which was really good experience so far! We haven't faced any issue yet but I would like if they will fix some of their minor bugs/issues in future releases because it's not that bad at all!! Currently we use this tool only when there is need of real time analytics then why should one go through other tools? This helps us solve problems related to event processing where events keep coming into stream every second hence making them processable within seconds without waiting too much longer than usual.
