\begin{itemize}

\item \textbf{Control} of your infrastructure

\begin{block}{Requirements}
|

|
|
\begin{itemize}
|
||
|
|
\item \textbf{No single point of failure} / flat hierarchy:
|
||
|
|
|
||
|
|
Any node can die for extended periods of time.
|
||
|
|
\item \textbf{Multi-site}: cluster spans regions/countries.
|
||
|
|
\item \textbf{Acceptable performance}.
|
||
|
|
\item \textbf{Lightweight}: targets legacy hardware.
|
||
|
|
\item \textbf{Conceptually simple}: built for low-tech organisations.
|
||
|
|
|
||
|
|
Adding/maintaining cluster nodes should be easy.

\item Decent performance despite bad inter-node connectivity.

\item Tailoring workloads as a function of nodes' capabilities:
|
||
|
|
|
||
|
|
\begin{itemize}
|
||
|
|
\item Make use of low-end nodes (e.g. Raspberry Pis),
|
||
|
|
\item Avoid impeding global performance because of low-end nodes.
|

|
|
\end{itemize}

\item Building CRDTs for target use-cases:
|

|
|
|
||
|
|
\begin{itemize}
|
||
|
|
\item Software engineering: DSL or native code?
|

|

\item Provide APIs to data store users? Risky?
