Memcache Plus Plus Plus - Bettererer Memcache module for Node js. Forked from the memcache-pp module, which was forked from memcache-plus, so you can find many refs to the memcache-plus in the docs or code itself.
- Removed hashring and replaced it with a simple cycle through each host
- Fixed uncaught exception errors when retrieving certain data values
- Support multiline/empty string/values where the data is a keyword (such as END) properly
- Added missing touch/gat/gats commands
- getMulti/gatMulti send one one command to request all keys at once instead of a loop of many requests
- Fixed potential race condition when using 2+ hosts requesting the same key at the same time
Edit your /etc/memcached.conf and comment out / add lines such as:
# -p 11211
# -l 127.0.0.1
-s /var/run/memcached/memcached.sock
-a 777
Then use in your code with:
import MemcachePlus from 'memcache-ppp';
const memcache = new MemcachePlus({ "hosts": ["/var/run/memcached/memcached.sock:0"] });
const [value, cas] = await memcache.gets('key');
if (!await memcache.cas('key', 'newvalue', cas)) {
// value changed between our gets() and cas() calls
}
memcache.touch(key, ttl);
memcache.gat(key, ttl, opts);
memcache.gats(key, ttl, opts);
- Many people use only a single server on localhost, or a unix socket, making it pointless anyway
- It is CPU intensive to calculate a MD5 hash of every key for every operation
- Hashring's internal cache grows up to several GB of RAM in less than a day
- Native support for Promises or Callbacks
- Elasticache auto discovery baked in
- Actively developed and used
- Focus on cleanliness and simplicity
- Command buffering - start issuing commands right away, memcache-plus will automatically wait until connected then flush that buffer
- Ability to disable with just a flag on init - sounds trivial, but nice to test with memcache off without altering any of your code
- Compression built in on a per item basis
Cached retrieve (coming soon!) - simply pass a function for retrieving a value and a key and memcache-plus will do the whole "check key, if it exists return it, if not run the function to retrieve it, set the value, and return it" for youSupport for binaries (coming soon!) which the other memcache libraries for Node don't support- (these things are not coming here)
