Yandex Database — how we guarantee fault tolerance

For providing fault tolerance of Yandex Database, we use our own algorithm of achieving distributed consensus as well as several technical solutions explored in this talk.

The Azul Hardware Transactional Memory experience

Azul made a really strong Hardware Transactional Memory, and yet in practice it was not good enough to run Java synchronized blocks concurrently — and Cliff will tell you why it didn't work and why HTM/STM in general will not allow concurrent execution in practice.

Dmitry Vyukov

Google

Day 2 / 16:30 / Track 1 / EN /

Goroutines exposed

Dmitry will look inside of the Go scheduler and expose how magic of goroutines is implemented.

Roman Elizarov

JetBrains

Day 2 / 14:30 / Track 2 / EN / Введение в технологию

Structured concurrency

We'll tell the story of the path that we went through when designing concurrency libraries for Kotlin programming language.

Leslie Lamport

Microsoft

Day 1 / 12:00 / Track 2 / EN / Для практикующих инженеров

Q & A

Attendees will be expected to watch videos of Leslie's talks "Programming Should Be More Than Coding" and "If You're Not Writing a Program, Don't Use a Programming Language", and Leslie will answer questions related to the topics of these talks. Each attendee should prepare at least one question.

Michael Scott

University of Rochester

Day 2 / 18:00 / Track 1 / EN /

Dual data structures

How java.util.concurrent.SynchronousQueue and java.util.concurrent.Exchanger work, and why you should care if you write multithreaded code.

Heidi Howard

University of Cambridge

Day 1 / 14:00 / Track 2 / EN /

Liberating distributed consensus

We revisit the underlying theory behind Paxos, weakening its original requirements and generalising the algorithm.

Lin-Check: Testing concurrent data structures in Java

Description will be announced soon

Day 2 / 11:00 / Track 2 / EN / Введение в технологию

Accelerating distributed graph analysis by means of probabilistic sketches (and not only them)

We'll discuss several tricks we use at OK for working with big graphs.

Day 2 / 16:30 / Track 2 / EN /

The cost of distributed transactions between arbitrary databases

This talk's main purpose is to introduce protocols of distributed transactions invented in the last few years, which can be implemented on client side on any cloud storage supporting compare-and-set.

Semyon Checherinda

Yandex

Day 2 / 14:30 / Track 1 / RU / Для практикующих инженеров

Distributed transactions in YDB

We'll explore transaction planning algorithm which Yandex Database (YDB) transactional system is based on. We'll see which entities participate in transactions, who sets global order for the transactions, and how transaction atomicity, reliability and high-level isolation are achieved.

Maurice Herlihy

Brown University Computer Science Dept

Day 1 / 19:00 / Track 1 / EN / Введение в технологию

Blockchains and the future of distributed computing

This talk surveys the theory and practice of blockchain-based distributed systems from the point of view of classical distributed computing, and how treating blockchains as a distributed computing problem simplifies everything.

Ori Lahav

Tel Aviv University

Day 2 / 12:30 / Track 1 / EN /

Weak memory concurrency in C/C++11

Ori will introduce the formal underpinning of the C/C++ concurrency model from 2011 and the key ideas behind it. He will discuss some of the flaws of the model, ways of correcting it, and some remaining open problems.

Pedro Ramalhete

Cisco Systems

Wait-free data structures and wait-free transactions

Learn how to make a wait-free data structure.

Alexey Zinoviev

Apache Ignite Committer

Day 1 / 17:30 / Track 2 / RU / Введение в технологию

Not all ML algorithms go to distributed heaven

Alexey will tell about problems of adapting classic machine learning algorithms for distributed execution from his experience of working with Apache Spark ML, Apache Mahout, Apache Flink ML and creating Apache Ignite ML.

Alex Petrov

Day 1 / 17:30 / Track 1 / EN / Для практикующих инженеров

Reduce your storage costs with Transient Replication and Cheap Quorums

We discuss Witness Replicas, a replication scheme used in Spanner and Megastore, and Apache Cassandra implementation of this concept, called Transient Replication and Cheap Quorums.

Martin Kleppmann

University of Cambridge

Day 1 / 10:30 / Track 1 / EN /

Syncing data across user devices for distributed collaboration

An update on the latest research on Conflict-free Replicated Data Types (CRDTs).

Cliff Click

CRATUS

Day 2 / 11:00 / Track 1 / EN / Введение в технологию

The H2O distributed K/V algorithm

A fast (typically under a microsecond) and exact (Java Memory Model) distributed key/value store.

Oleg Anastasyev

Odnoklassniki

Day 1 / 16:00 / Track 1 / RU / Для практикующих инженеров

Efficient microservices in the NoSQL world

We'll cover the advantages of combining business logic with database, discuss how this technique affects reliability and accessibility of services and how it allowed us to make our services considerably faster.
