Hi,
Attached is v2 of the patch to add threshold-based sleep to
XactLockTableWait functions.
Changes from v1:
- Simplified approach based on Fujii's feedback [1]: instead of exponential
backoff,
we now sleep 1ms for the first 5 seconds, then switch directly to 1s
sleeps
- Reduced the threshold from 10 seconds to 5 seconds to avoid excessive
delays
