Avoid PostgreSQL LWLock:buffer_content locks in Amazon Aurora: …

PostgreSQL utilizes lightweight locks (LWLocks) to synchronize and control access to the buffer content. A process acquires an LWLock in a shared mode to read from the buffer and an exclusive mode to write to the buffer. Therefore, while holding an exclusive lock, a process prevents other processes from acquiring a shared or exclusive lock. Also, a shared lock can …

Re: [PATCH] Identify LWLocks in tracepoints

I'd like to move the LWLock->waiters list to outside of the lwlock itself - at most TotalProcs LWLocks can be waited for, so we don't need millions of empty proclist_heads. That way we could also remove the proclist indirection - which shows up a fair bit in contended workloads. And if we had a separate "lwlocks being waited for" structure, we could also add …
