------------------------------
Summary: Summary Task Metrics for Stage Page: Efficient
implimentation for SHS when using disk store.
Key: SPARK-26260
URL: https://issues.apache.org/jira/browse/SPARK-26260
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.4.0, 3.0.0
Reporter: shahid
Currently, tasks summary metrics is calculated based on all the tasks, instead
of successful tasks.
After the JIRA, https://issues.apache.org/jira/browse/SPARK-26119, when using
InMemory store, it find task summary metrics for all the successful tasks
metrics. But we need to find an efficient implementation for disk store case
for SHS. The main bottle neck for disk store is deserialization time overhead.
Hints: Need to rework on the way indexing works, so that we can index by
specific metrics for successful and failed tasks differently (would be tricky).
Also would require changing the disk store version (to invalidate old stores).
