--------------------------------------
Summary: Server-side processing of History UI list of applications
Key: SPARK-31196
URL: https://issues.apache.org/jira/browse/SPARK-31196
Project: Spark
Issue Type: Improvement
Components: Web UI
Affects Versions: 2.3.0
Reporter: Pavol Vidlička
Loading the list of applications in the History UI does not scale well with a
large number of applications. Fetching and rendering the list for 10k+
applications takes over a minute.
Using `spark.history.ui.maxApplications` is not a great solution, because (as
the name implies), it limits the number of applications shown in the UI, which
hinders usability of the History Server.
A solution would be to use [server side processing of the
DataTable](https://datatables.net/examples/data_sources/server_side). This
would limit amount of data sent to the client and processed by the browser.
This proposed change plays nicely with KVStore abstraction implemented in
SPARK-18085, which was supposed to solve some of the scalability issues.
