-----------------------------------
Labels: pull-request-available (was: )
> Register progress handlers, and call them with the progress of each
> execution, in the Python client as PySpark does
> -------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-61084
> URL: https://issues.apache.org/jira/browse/SPARK-61084
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: connect-rust-4.3.0
> Reporter: Hyukjin Kwon
> Priority: Major
> Labels: pull-request-available
> Fix For: connect-rust-4.3.0
>
>
> In PySpark Connect, {{spark.registerProgressHandler(handler)}} registers a
> callable once (it returns None), {{removeProgressHandler(handler)}} removes
> that callable (a {{ValueError}} if it is not registered), and the client
> calls each handler with the keyword arguments of {{ProgressHandler}}:
> {{stages}} (the {{StageInfo}} of each stage), {{inflight_tasks}},
> {{operation_id}} and {{done}}, for each progress of an execution and once
> more with {{done=True}} when it ends. {{pyspark.sql.connect.shell.progress}}
> has {{ProgressHandler}}, {{StageInfo}} and the {{Progress}} bar of
> {{SPARK_CONNECT_PROGRESS_BAR_ENABLED}}.
> The Rust-backed Python client returns an id of {{registerProgressHandler}},
> removes a handler by that id, and calls a handler with one dict of the
> progress, so a handler of PySpark fails. It lacks
> {{pyspark.sql.connect.shell.progress}}. Register and call the handlers as
> PySpark does.
