PostgreSQL JSON Roadmap
The new ISO/IEC 9075-2:2016 standard specifies JSON data and operations syntax and semantics specifics for SQL. This talk overviews the requirements of this standard, and focuses on the differences between them and the actual implementation of JSON/JSONB in PostgreSQL. Special attention will be paid to JSON Path (XPath analogue), SQL/JSON functions and our plans to make Postgres compliant with this standard.

Buit-in Sharding update and future
Database sharding enables a distribution of the database over a large number of machines, greatly improving performance. With the advent of Foreign Data Wrappers (FDW), it's possible to consider a database sharding in PostgreSQL with acceptable level of code changes using FDW. We've been working on enhancing around FDW infrastructure such as foreign table inheritance and pushing down so that PostgreSQL can execute the distributed query efficiently using FDW. In this talk, I'll cover what FDW-based sharding is and what use-cases it can cover. And then I'll demonstrate how to build sharding and describe our achievement of a FDW-based sharding in PostgreSQL community. Finally, I'll describe further enhancements to FDW such as Async Execution and Distributed Transaction Support.

Alexander Kukushkin Zalando SE
In the modern world, an increasing number of IT companies are moving their resources to the cloud and Zalando is not an exception. A rapid growth our company is experiencing along with an adoption of microservices were the main driving forces behind the changes introduced into the deployment procedure of new PostgreSQL clusters and the solution of the automatic failover problem. The majority of existing solutions for automatic failover require manual configuration of every cluster instance and complicates provisioning new clusters and new nodes into existing cluster.

Michael Kagan Mellanox Technologies
Building high-performance scale-out Database Solutions
Modern high-performance and scale-out Database solutions need to move huge amounts of data between the system components. They need to perform it quickly and without delay for the end-user. While developing interconnect technologies Mellanox focuses on highest bandwidth, ultra-low latency, and advanced CPU offload capabilities. In this session Michael will tell about fast interconnect value for Database and Big Data solutions and will share Mellanox experience in building such systems in cooperation with leading global vendors.
