Re: smart client proxy for cassandra

[aaron morton]

I've heard of people using HA Proxy  http://haproxy.1wt.eu/ with php as a 
connection pool.

Note that detecting failure in Cassandra can only be done as part of a request. 
So HA Proxy cannot understand if a node is actually functional, only that it 
allows a socket to be opened. 

There is some work being done on creating a proxy server with Hector 
https://github.com/rantav/hector/tree/lcp-first-cut Not sure on it's progress.

 I'd like to proxy short lived phpcassa connections through a smart proxy that 
 will manage a pool of connections and be aware of current cluster state, 
 bad/slow nodes etc...
 The java php libraries https://github.com/s7/scale7-pelops and 
 https://github.com/Netflix/astyanax looks like good choices.
 But since I'm not a java programmer I'd first check if someone already have 
 done this or if someone could give guidelines on how to extend one of the 
 above java clients to also proxy thrift connections.
 
 Thanks
