NAME
Tie::Redis - Connect perl data structures to Redis
VERSION
version 0.26
SYNOPSIS
use Tie::Redis;
tie my %r, "Tie::Redis";
$r{foo} = 42;
print $r{foo}; # 42, persistentlyDESCRIPTION
This allows basic access to Redis from Perl using tie, so it looks just like a a hash or array.
Please think carefully before using this, the tie interface has quite a performance overhead and the error handling is not that great. Using AnyEvent::Redis or Redis directly is recommended.
General usage
Tie::Redis provides an interface to the top level Redis "hash table"; depending on the type of key you access this then returns a value tied to Tie::Redis::Hash, Tie::Redis::List, Tie::Redis::Scalar or a set type (unfortunately, these aren't yet implemented).
If an error occurs these types will throw an exception, therefore you may want to surround your Redis accessing code with an eval block (or use Try::Tiny).
Issues
There are some cases where Redis and Perl types do not match, for example empty lists in Redis have a type of "none", therefore if you empty a list and then try to access it again it will no longer be an array reference.
Autovivification currently doesn't correctly work, I believe some of this may be fixable but haven't yet fully investigated.
