Hyukjin Kwon updated SPARK-61038:
---------------------------------
Description:
In PySpark Connect, {{df.writeStream.trigger(...)}} takes exactly one of
{{processingTime}}, {{once}}, {{continuous}}, {{availableNow}} and
{{realTime}}, and raises {{ONLY_ALLOW_SINGLE_TRIGGER}} for none or more than
one. An interval or duration is a non-empty string, which it strips, else
{{VALUE_NOT_NON_EMPTY_STR}}, and {{once}} and {{availableNow}} are {{True}},
else {{VALUE_NOT_ALLOWED}}. {{trigger(realTime="5 seconds")}} sets the
real-time trigger of the query, the {{real_time_batch_duration}} of its
{{WriteStreamOperationStart}}.
The Rust-backed Python client raises {{NotImplementedError: the realTime
trigger is not yet supported by this client}} for {{realTime}}. It takes the
first trigger of several, raises a plain {{ValueError}} for none and for
{{once=False}}, and sends an empty or unstripped interval. Take the trigger as
PySpark does.

Summary: Take the triggers of DataStreamWriter.trigger, including
realTime, in the Python client as PySpark does (was: Take the realTime trigger
