Public bug reported:
Tested this on Ubuntu 12.10 x86_64
mysql-proxy 0.8.1-1.1build1 experiences a segfault under any load or
after a few minutes of running idle (it is very fragile). I am getting
the same occurrence with current EPEL (0.8.2-1.el6), although it seems
to hold up for several seconds under mysqlslap. This tells me there is
probably a bug in upstream mysql-proxy. The segfault occurs somewhere
in libmysql-proxy.so.0.0.0.
mysql-proxy is the only useful way to do command splitting in a database
cluster such that a single MySQL port served on 3306 on a single server
will send non-transactional SELECT (read) statements to one server/port
and all other statements to another server/port. With the two back-ends
being haproxy with load balancing (for read) and fail-over (for write),
this allows for spreading database reads across a high-availability
cluster, while keeping writes directed at a single active master which
fails over transparently.
Without mysql-proxy, only simple fail-over is possible. This directs
all load to a single server and does not scale.
It is notable mysql-proxy is in Universe, so the above explanation of
functionality does not elevate it above critical main packages.
