The Past, Present and Future of Enterprise IT in a Cloud-Native World

James Watters, SVP Products, Pivotal

Today's modern enterprise applications and services are being designed from the ground up to support multi-cloud, hybrid and cloud-native environments. This is primarily being done to accelerate software delivery, ensure application portability and/or to satisfy security or compliance requirements. These cloud-native requirements are being similarly extended to the underlying database infrastructure that applications rely on. In this keynote, Jame Watters, SVP of Strategy at Pivotal, will walk us through the evolution, benefits and challenges that enterprise IT faces in transforming how it delivers applications, security, automation and data in a cloud-native first world.

Building planet-scale cloud-native apps with GraphQL and distributed SQL

Tanmai Gopal, CEO/Co-Founder, Hasura

Modern apps have users and data that are distributed all over the world. Cloud-native patterns allow developers to run their compute on infrastructure that is also spread globally. However, building these applications involves putting together a lot of different tools and patterns which makes it hard to move fast and slows down delivery. I will introduce GraphQL as a modern API layer that is helping developers accelerate product delivery and the patterns / challenges in making GraphQL work with distributed SQL. I’m going to discuss architectures, recipes and show you demos of a modern and seamless developer experience for application developers.

Google Spanner's SQL Evolution

Campbell Fraser, Software Development Lead, Google

Spanner is a globally-distributed data management system that backs hundreds of mission-critical services at Google. Spanner is built on ideas from both the systems and database communities. The first Spanner paper published at OSDI 2012 focused on the systems aspects such as scalability, automatic sharding, fault tolerance, consistent replication, external consistency, and wide-area distribution. A subsequent paper in SIGMOD 2017 highlighted the database DNA of Spanner. This presentation builds on that second paper; we describe distributed SQL query execution in the presence of resharding, query restarts upon transient failures, range extraction that drives query routing and index seeks, and the improved blockwise columnar storage format. We touch upon the common SQL dialect shared with other systems at Google.

Strongly Consistent Global Indexes for Phoenix

Kadir Ozdemir, Principal Architect, Salesforce

Without transactional tables, the global indexes can get easily out of sync with their data tables in Apache Phoenix. Transactional tables require a separate transaction manager, have some restrictions and performance penalties, are still in beta. This technical talk lays out a design to have strongly consistent global indexes without the need for an external transaction manager. In addition to having strongly consistent indexing, the proposed design aims to have minimal impact on read performance. In Phoenix, global indexing is implemented using a separate table for each secondary index of a table. Updating a table with one or more global index requires updating multiple table regions likely distributed over multiple region servers. Translating a single table update operation into a multi-table write operation poses consistency issues as Phoenix does not provide a reliable multi-table update capability without using transactional tables. Although updating multiple tables (in our case, a data table and its indexes) atomically requires implementing a form of two-phase commit protocol, we have observed that achieving strongly consistent global indexing does not require implementing a general-purpose transaction capability. Another important observation is that HBase is a log-structured data store, that is, updates are never done in place. In these systems, writes are much faster when compared to in-place update systems because random writes are handled as fast as sequential writes. This allows us to add an extra write phase during updates without severely impacting the write performance, which simplifies the overall design. In this talk, we will present the details of the proposed design, the proof of its correctness, and our performance analysis and test results.

Benchmarking Distributed SQL Databases

Robert Winslow, Performance Engineer &, Data Scientist

Traditional RDBMS databases run on a single node, and therefore the benchmarks designed for these systems make that implicit assumption. Distributed SQL databases are a new breed that operate on a cluster of nodes. These databases have fundamentally different architectures, requiring a different benchmarking methodology. For example, the network latency between the nodes begins to dominate the write latency since data is replicated synchronously. Understanding the impact of network latency is critical to getting optimal performance. In this talk, we will look at the transactional cloud serving benchmark or TCSB framework built to benchmark distributed, transactional databases, and the results of benchmarking a few such DBs.

How-To: Zero Downtime Migrations from Oracle to a Cloud-Native PostgreSQL

Rajkumar Sen, Chief Technical Architect, Founder, BlitzzIO

Legacy applications are transforming rapidly. They are being broken down into cloud-native microservices. This phase is followed by a database transformation phase, where the database tier comprising legacy is modernized. Distributed SQL databases being cloud-native and feature-rich are a great migration choice. In this talk, we will look at what database features are required to replace legacy databases like Oracle in the cloud, along with various do’s and don’ts. We will also look at a live demo of migrating an Oracle database to a distributed SQL database.

Spring Forward to a Cloud-Native PostgreSQL

Guillermo Tantachuco, Principal Platform Architect, Pivotal
Nikhil Chandrappa, Senior Platform Architect, Pivotal

Business critical applications of the past are monolithic in design and run on proprietary databases like Oracle. These are being transformed into microservice-based cloud-native applications using popular frameworks like Spring - while the database itself is moving to cloud-native PostgreSQL deployments and distributed SQL databases. This talk will cover how Spring is evolving to enable building microservices on distributed SQL databases using a real world example. We will look at cloud-native aspects such as how to eliminate the load balancer by using cluster-aware SQL drivers, making discovery of the underlying database topology possible in applications and using reactive programming against SQL using R2DBC in the context of the application. Finally, we will conclude with a summary of the work actively happening in this area and what the future holds.
