A stream processing engine that stays correct when processes die. SQL or typed C++ over event time and keyed state, with exactly-once delivery and twenty-plus connectors: brokers, CDC, databases, lakehouse tables, graphs. The same pipeline runs on a single machine, inside a service or scaled out across a highly available cluster. Arrow-native C++.
