\frametitle{Modèles de cohérence}
|
||||||
|
Garage utilise un modèle de cohérence relativement faible :
|
||||||
|
\vspace{1em}
|
||||||
|
|
||||||
|
\begin{itemize}
|
||||||
|
\item Objets répliqués 3 fois, quorum de 2 pour les lectures et les écritures\\
|
||||||
|
$\to$ cohérence \textbf{``read your writes''}
|
||||||
|
\vspace{1em}
|
||||||
|
\item<2-> Types de donnée CRDT + mécanisme d'anti-entropie\\
|
||||||
|
$\to$ cohérence \textbf{à terme} (eventual consistency)
|
||||||
|
\vspace{1em}
|
||||||
|
\item<3-> Cela s'applique pour chaque fichier individuellement :\\
|
||||||
|
pas de linéarisabilté ou de cohérence causale entre les opérations\\
|
||||||
|
sur des fichiers différents
|
||||||
|
\vspace{1em}
|
||||||
|
\item<4-> \textbf{Avantage :} convient bien à un déploiement géodistribué (multi-datacenter)
|
||||||
|
