Authentication failures are currently only logged for CORE clients.
This change puts the logging in a central location which all protocols
use for authentication so that authentication failures are logged for
all protocols.
Calling close multiple times on ServerConsumer can result in multiple
notifications being routed around the cluster. This causes cluster
topology info to become skewed. Which affects a number of components
such as message redistribution, metrics and can eventually cause OOM
should multiple queues be redistributing at the same time.
After sending pages, the thread will hold the storage manager write lock
and send synchronization finished packet(use the parent thread pool) to
the backup node. At the same time, thread pool is full bcs they are
waiting for the storage manager read lock to write the page or journal,
leading to replication starting failure. Here we use io executor to send
replicate packet to fix thread pool starvation problem.
Quorum voting is used by both the live and the backup to decide what to do if a replication connection is disconnected.
Basically, the server will request each live server in the cluster to vote as to whether it thinks the server it is replicating to or from is still alive.
You can also configure the time for which the quorum manager will wait for the quorum vote response.
Currently, the value is hardcoded as 30 sec. We should change this 30-second wait to be configurable.
