Problem

ETL jobs fail or terminate unexpectedly due to timeout errors during execution.

Root Cause Analysis (RCA)

The ETL timeout issue was caused by long-running database queries processing large datasets without optimized indexing. During peak execution windows, the ETL process exceeded the scheduler-configured timeout threshold, resulting in automatic job termination.

Solution

The issue was resolved by increasing the ETL scheduler timeout limit, optimizing long-running SQL queries, and adding indexes to high-volume database tables. ETL batch sizes were reduced and overlapping jobs were rescheduled to minimize server load.

Implemented fixes:

• Increased timeout configuration from 1800s to 7200s.

• Optimized database queries.

• Added required indexes.

• Reduced ETL batch processing volume.

• Improved resource allocation.

Result:

• ETL jobs completed successfully.

• No further timeout failures observed.

• Improved overall ETL performance.
