Build Stuff'15 Lithuania

In this talk, Oren will discuss the building blocks of building a reliable, transactional distributed database.
In particular, this session will cover ACID compliance, ensuring consistency between distributed nodes (with failure handling), monitoring and management, dissemination of information in the system, and more.

Consensus is fundamental to building fault-tolerant systems, but it's poorly understood. We struggled to build a complete system using Paxos, so we developed the Raft consensus algorithm to be easier to understand. Since releasing our first paper draft in 2012, Raft has been implemented in dozens of libraries and systems, and it's now taught at over ten universities. In this talk, I'll give an overview of how Raft works. More info on Raft can be found at https://raft.github.io .

The Lightning Memory-Mapped Database (LMDB) was introduced at LDAPCon 2011 and has been enjoying tremendous success in the intervening time. LMDB was written for the OpenLDAP Project and has proved to be the world's smallest, fastest, and most reliable transactional embedded data store. It has cemented OpenLDAP's position as world's fastest directory server, and its adoption outside the OpenLDAP Project continues to grow, with a wide range of applications including big data services, crypto-currencies, machine learning, and many others.

The talk will cover highlights of the LMDB design as well as the impact of LMDB on other projects.
