Reliability Analysis of Deduplicated and Erasure-Coded Storage

HPL-2010-146 Reliability Analysis of Deduplicated and Erasure-Coded Storage - Li, Xiaozhou; Lillibridge, Mark; Uysal, Mustafal
Keyword(s): Deduplication, erasure coding
Abstract: Space efficiency and data reliability are two primary concerns for modern storage systems. Chunk-based deduplication, which breaks up data objects into single-instance chunks that can be shared across objects, is an effective method for saving storage space. However, deduplication affects data relia ...

MooseX::Storage::Engine::Trait::DisableCycleDetection(3)User Contributed Perl DocumentatioMooseX::Storage::Engine::Trait::DisableCycleDetection(3)

NAME
MooseX::Storage::Engine::Trait::DisableCycleDetection - A custom trait to bypass cycle detection SYNOPSIS
package Double; use Moose; use MooseX::Storage; with Storage( traits => ['DisableCycleDetection'] ); has 'x' => ( is => 'rw', isa => 'HashRef' ); has 'y' => ( is => 'rw', isa => 'HashRef' ); my $ref = {}; my $double = Double->new( 'x' => $ref, 'y' => $ref ); $double->pack; DESCRIPTION
"MooseX::Storage" implements a primitive check for circular references. This check also triggers on simple cases as shown in the Synopsis. Providing the "DisableCycleDetection" traits disables checks for any cyclical references, so if you know what you are doing, you can bypass this check. This trait is applied to an instance of MooseX::Storage::Engine, for the user-visible version shown in the SYNOPSIS, see MooseX::Storage::Traits::DisableCycleDetection METHODS
