Cache invalidation synchronization routines:
......@@ -9,23 +9,9 @@ backend can register a message which then has to be read by
all backends. A message read by all backends is removed from the
queue automatically. If a message has been lost because the buffer
was full, all backends that haven't read this message will be
noticed that they have to reset their cache state. This is done
told that they have to reset their cache state. This is done
at the time when they try to read the message queue.
The message queue is implemented as a shared buffer segment. Actually,
the queue is a circle to allow fast inserting, reading (invalidate data) and
maintaining the buffer.
Access to this shared message buffer is synchronized by the lock manager.
The lock manager treats the buffer as a regular relation and sets
relation level locks (with mode = LockWait) to block backends while
another backend is writing or reading the buffer. The identifiers used
for this special 'relation' are database id = 0 and relation id = 0.
The current implementation prints regular (e)log information
when a message has been removed from the buffer because the buffer
is full, and a backend has to reset its cache state. The elog level
is NOTICE. This can be used to improve the behavior of backends
when invalidating or resetting their cache state.
