----------------------------------------
Summary: Corruption Block Handling too slow in S3
Key: HUDI-1310
URL: https://issues.apache.org/jira/browse/HUDI-1310
Project: Apache Hudi
Issue Type: Sub-task
Components: Writer Core
Reporter: Balaji Varadarajan
The logic to figure out next valid starting block offset is too slow when run
in S3.
I have bolded the log message that takes long time to appear.
