Pavol Vidlička updated SPARK-31196:
-----------------------------------
Description:
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.
