Readme for memcache-0.0.1
[back to package description]memcache: Haskell Memcache Client
This library provides a client interface to a Memcache cluster. It is aimed at full binary protocol support, ease of use and speed.
Licensing
This library is BSD-licensed.
Tools
This library also includes a few tools for manipulating and experimenting with memcached servers.
OpGen-- A load generator for memcached. Doesn't collect timing statistics, other tools like mutilate already do that very well. This tool is useful in conjunction with mutilate.Loader-- A tool to load random data of a certain size into a memcache server. Useful for priming a server for testing.
Architecture Notes
We're relying on Data.Pool for thread safety right now, which is
fine but is a blocking API in that when we grab a socket
(withResource) we are blocking any other requests being sent over
that connection until we get a response. That is, we can't pipeline.
Now, use of multiple connections through the pool abstraction is an easy way to solve this and perhaps the right approach. But, could also implement own pool abstraction that allowed pipelining. This wouldn't be a pool abstraction so much as just round-robbining over multiple connections for performance.
Either way, a pool is fine for now.
ToDo
Required:
- Connection error handling
- SASL -- tie in with cluster management
- Timeouts
- Pull cluster and server creation into client
Optional:
- Multi-get
- Generic multi operation support
- Customizable server sharding -- mod & virtual servers
Nice-to-have:
- Asynchronous support
- Customizable -- timeout, max connection retries, hash algorithm
- Max value validation
- Optimizations -- http://code.google.com/p/spymemcached/wiki/Optimizations
- UDP
- ASCII
- Server error handling mode where we return misses and ignore sets
Maybe:
- Typeclass for serialization
- Monad / Typeclass for memcache
