NAME
ShardedKV::Storage - Role for classes implementing storage backends
VERSION
version 0.17
SYNOPSIS
package ShardedKV::Storage::MyBackend;
use Moose;
with 'ShardedKV::Storage';
sub get { ... }
sub set { ... }
sub delete { ... }
sub reset_connection { ... }
1;DESCRIPTION
ShardedKV::Storage provides a role/interface that storage backends must consume. Consuming the role requires implementing the three important operations necessary for a storage backend. There are a few storage backends that come with ShardedKV. Please see those modules for their specific details.
ROLE REQUIRES
get
get() needs to accept a key of some sort and return whatever is relevant.
set
set() needs to accept both a key, and a reference to a datastructure suitable for storing
delete
delete() needs to accept a key and it must remove the data stored under that key
reset_connection
Storage backends must implement reset_connection() to allow for reconnects. Since most things are not reentrant and signals can mess with the state of sockets and such, the ability to reset the connection (whatever that means for your particular storage backend), is paramount.
