High Availability


Last year, we joined percona live the very first time and bring the world AliSQL, a MySQL branch maintained by Alibaba Database Team. We share many improvements we made on AliSQL, including Column Compression, Double Redo Buffer, "Hot SKU", SQL Firewall, and so on. Some of these improvements have been absorbed by the Mainstream. Nevertheless, this is not the end of the story of AliSQL, this year we made even more breakthrough on AliSQL, which made AliSQL more and more approaching the goal of high performance, high availability and low maintaining cost: * Optimized InnoDB Memcached Plugin for high performance and easy to use * Boosted "Hot SKU" for 2016 Alibaba Singles's Day shopping festival * We implemented Paxos/Raft for AliSQL, which made AliSQL an integrated system: self-maintaining with no external dependencies, auto leader election, no data-loss during failover, online member ship changing. Comparing to MySQL Group Replication, we brought many new ideas.
