Hi Dilip, Amit,
Thank you for the patch!
I test the patch on the master HEAD(9796f455) and it works fine.
* make installcheck-world: passed
* walsender process continues to use 100% of the CPU 1core when
TRUNCATE 1000 partition: 1s or less
** before patch : 230s
There is "ReorderBufferAddInvalidation" in reorderbuffer.h, but I
don't think it's needed.
src/include/replication/reorderbuffer.h
+void ReorderBufferAddInvalidation(ReorderBuffer *, TransactionId,
XLogRecPtr lsn,
+ int nmsgs, SharedInvalidationMessage *msgs);
If possible, I'd like to improve it even before PG13,
but I recognize that it's difficult because it uses a PG14 or later
mechanism...
Best Regards,
