Hi Dinesh,

They are different projects that aim to solve different problems. 
The streaming ledger goal is to bring serializable ACID Transactions to streaming pipelines, while statefun's aim is to simplify building distributed stateful applications in the serverless model.
To get more information about the motivation behind statefun I'd recommend watching a recent keynote given at the previous Flink Forward [1]

Hi Team,

Is streaming ledger is replaced by statefulfun.io. Or am i missing something?

Thanks and regards,
