There is a tool: ceilometer-expirer

I tried to use it on a mysql database, since I had the same table size 
problem as you and it made the machine hit swap. I think it tries to 
load the whole table in memory.
Just to see if it would eventually finish, I let it run for 1 week 
before throwing away the whole database and move on.

Now I use Ceilometer's pipeline to forward events to elasticsearch via 
udp + logstash and do not use Ceilometer's DB or API at all.


Best,
