fort-knox

An implementation of core.cache that saves entries to disk.

You get a chance to use LevelDB (default) or LMDB.

DISCLAIMER typical core.cache implementations use persistent and associative data structures. Since a disk-backed key-value store doesn't have any such concept, this implementation might not conform to expected behavior.

Usage

Import this implementation:

user> (use 'fort-knox.core :reload-all)
nil

Create a cache (LevelDB by default):

user> (def cache (make-cache "/tmp"))
#'user/cache

If you want to use LMDB:

user> (def cache (make-cache "/tmp" :type :lmdb))
#'user/cache

Everything else is from core.cache. For example:

user> (cache/has? cache "foo")
false
user> (cache/miss cache "foo" "bar")
{:env #object[org.fusesource.lmdbjni.Env 0x6e09d885 "org.fusesource.lmdbjni.Env@6e09d885"], :db #object[org.fusesource.lmdbjni.Database 0x65807b47 "org.fusesource.lmdbjni.Database@65807b47"]}
user> (cache/has? cache "foo")
true
