@nbali it can be a bit confusing, but the `isStreaming` pipeline option is not actually part of the core Beam model. It is a runner-specific option. Spark and Dataflow have separate batch/streaming modes. The direct runner and Flink runner don't need this. Really "streaming" is the universal mode that works for everything, while batch is a special case that allows optimizations because all the data is bounded (so we can do more splitting up front, and don't need to checkpoint and pause, etc). -- This is an automated message from the Apache Git Service.
