Hello, users! At the moment our analysts often use mixes of interpreters in their notes. For example, they prepare data using %jdbc and then use it in %pyspark. Besides, they often use scheduling to make some regular reporting. And they should do something like `time.sleep()` to wait for the data from %jdbc. It doesn`t guarantee the result and doesn`t look cool. You can find early attempts to implement sequential running of all paragraphs in [1]. We are really interested in implementation of the issue [2] and are ready to solve it. It seems a good idea to discuss any requirements. My idea is to introduce note setting that defines the type of running to use (parallel or sequential) and leave "Run all" to be the only button running all the cells in the note. This will make sequential or parallel running the `note option` but not `run option`. Option will be controlled by nearby button as shown [https://lh6.googleusercontent.com/jwnb7xfb0fPbFg1CWPoMSqovu7ecSMv4pJfuP4zdKVZbyAUDwzAT2GJ5EiemXVYrqMW73yklemTpjXNyLRJABpTCoHi6us2ZI_AxWKHwZpBEA7MjpMP0-7Nk8saaJQfIF4yBMPfS] For new notes the default state would be "Run sequential all", for old - "Run parallel for interpreters" We are glad to hear any thoughts. Thank you. [1] https://issues.apache.org/jira/browse/ZEPPELIN-1165 [2] https://issues.apache.org/jira/browse/ZEPPELIN-2368 Maksim Belousov
