Sets the time characteristic for all streams create from this environment, e.g., processing
time, event time, or ingestion time.
If you set the characteristic to IngestionTime of EventTime this will set a default
watermark update interval of 200 ms. If this is not applicable for your application
you should change it using
:func:`pyflink.common.ExecutionConfig.set_auto_watermark_interval`.
Example:
::
>>> env.set_stream_time_characteristic(TimeCharacteristic.EventTime)
:param characteristic: The time characteristic, which could be
:data:`TimeCharacteristic.ProcessingTime`,
:data:`TimeCharacteristic.IngestionTime`,
:data:`TimeCharacteristic.EventTime`.
