FoundationDB
FoundationDB是Apple維護的NoSQL資料庫。
安裝
在Ubuntu下可以使用官方打包好的deb安裝7.1版：
cd /tmp; wget -c https://github.com/apple/foundationdb/releases/download/7.1.65/foundationdb-clients_7.1.65-1_amd64.deb; sudo dpkg -i foundationdb-clients_7.1.65-1_amd64.deb; wget -c https://github.com/apple/foundationdb/releases/download/7.1.65/foundationdb-server_7.1.65-1_amd64.deb; sudo dpkg -i foundationdb-server_7.1.65-1_amd64.deb
也可以安裝7.3版，但我無法跑起cluster模式：
cd /tmp; wget -c https://github.com/apple/foundationdb/releases/download/7.3.43/foundationdb-clients_7.3.43-1_amd64.deb; sudo dpkg -i foundationdb-clients_7.3.43-1_amd64.deb; wget -c https://github.com/apple/foundationdb/releases/download/7.3.43/foundationdb-server_7.3.43-1_amd64.deb; sudo dpkg -i foundationdb-server_7.3.43-1_amd64.deb
設定
測試
先進入CLI介面：
fdbcli
在CLI的預設是唯獨模式，透過指令允許送出寫入操作：
writemode on
接著可以進行操作：
get a/b/c
set a/b/c foo
get a/b/c
clear a/b/c
get a/b/c
