Hi, I'm newbie in Flink and in streaming Engine and I'm starting to get familiar with and understand with the Stream API using examples that creates Its own Operator The examples used AbstractStreamOperator at version 1.0 and updating library to 1.4 I notice that restoreState snapshotOperatorState StreamTaskState were removed. Could you point me please some link where I can found some document about deprecation to understand how to replace that ?
Thanks for help --Filippo
