v.25.9Improvement
Slow down S3 client threads
Slow down S3 client threads on retryable errors in S3 Object Storage. This extends the previous settingbackup_slow_all_threads_after_retryable_s3_errorto S3 disks and renames it to the more generals3_slow_all_threads_after_retryable_error. #85918 (Julia Kartseva).
Why it matters
This feature improves stability and reliability of S3 object storage interactions by controlling client thread behavior during retryable errors, preventing excessive request failures and resource contention on S3 disks.How to use it
Enable or configure the new settings3_slow_all_threads_after_retryable_error to slow down all S3 client threads after encountering retryable errors on any S3 disk. This replaces the older backup_slow_all_threads_after_retryable_s3_error setting.
