Virtual Flink Forward 2020: Netflix Data Mesh: Composable Data Processing - Justin Cunningham
5 likes797 views
Netflix processes trillions of events and petabytes of data a day in the Keystone data pipeline, which is built on top of Apache Flink. As Netflix has scaled up original productions annually enjoyed by more than 150 million global members, data integration across the streaming service and the studio has become a priority. Scalably integrating data across hundreds of different data stores in a way that enables us to holistically optimize cost, performance and operational concerns presented a significant challenge. Learn how we expanded the scope of the Keystone pipeline into the Netflix Data Mesh, our real-time, general-purpose, data transportation platform for moving data between Netflix systems. The Keystone Platform’s unique approach to declarative configuration and schema evolution, as well as our approach to unifying batch and streaming data and processing will be covered in depth.

Free Training: How to Build a Lakehouse
Free Training: How to Build a LakehouseDatabricks Doug Bateman, a principal data engineering instructor at Databricks, presented on how to build a Lakehouse architecture. He began by introducing himself and his background. He then discussed the goals of describing key Lakehouse features, explaining how Delta Lake enables it, and developing a sample Lakehouse using Databricks. The key aspects of a Lakehouse are that it supports diverse data types and workloads while enabling using BI tools directly on source data. Delta Lake provides reliability, consistency, and performance through its ACID transactions, automatic file consolidation, and integration with Spark. Bateman concluded with a demo of creating a Lakehouse.
Achieving Lakehouse Models with Spark 3.0
Achieving Lakehouse Models with Spark 3.0Databricks It’s very easy to be distracted by the latest and greatest approaches with technology, but sometimes there’s a reason old approaches stand the test of time. Star Schemas & Kimball is one of those things that isn’t going anywhere, but as we move towards the “Data Lakehouse” paradigm – how appropriate is this modelling technique, and how can we harness the Delta Engine & Spark 3.0 to maximise it’s performance?

Data Mesh in Practice - How Europe's Leading Online Platform for Fashion Goes...
Data Mesh in Practice - How Europe's Leading Online Platform for Fashion Goes...Dr. Arif Wider A talk presented by Max Schultze from Zalando and Arif Wider from ThoughtWorks at NDC Oslo 2020.
Abstract:
The Data Lake paradigm is often considered the scalable successor of the more curated Data Warehouse approach when it comes to democratization of data. However, many who went out to build a centralized Data Lake came out with a data swamp of unclear responsibilities, a lack of data ownership, and sub-par data availability.
At Zalando - europe’s biggest online fashion retailer - we realised that accessibility and availability at scale can only be guaranteed when moving more responsibilities to those who pick up the data and have the respective domain knowledge - the data owners - while keeping only data governance and metadata information central. Such a decentralized and domain focused approach has recently been coined a Data Mesh.
The Data Mesh paradigm promotes the concept of Data Products which go beyond sharing of files and towards guarantees of quality and acknowledgement of data ownership.
This talk will take you on a journey of how we went from a centralized Data Lake to embrace a distributed Data Mesh architecture and will outline the ongoing efforts to make creation of data products as simple as applying a template.
Time to Talk about Data Mesh
Time to Talk about Data MeshLibbySchulze This document discusses data mesh, a distributed data management approach for microservices. It outlines the challenges of implementing microservice architecture including data decoupling, sharing data across domains, and data consistency. It then introduces data mesh as a solution, describing how to build the necessary infrastructure using technologies like Kubernetes and YAML to quickly deploy data pipelines and provision data across services and applications in a distributed manner. The document provides examples of how data mesh can be used to improve legacy system integration, batch processing efficiency, multi-source data aggregation, and cross-cloud/environment integration.

Improving SparkSQL Performance by 30%: How We Optimize Parquet Pushdown and P...Databricks The document discusses optimizations made to Spark SQL performance when working with Parquet files at ByteDance. It describes how Spark originally reads Parquet files and identifies two main areas for optimization: Parquet filter pushdown and the Parquet reader. For filter pushdown, sorting columns improved statistics and reduced data reads by 30%. For the reader, splitting it to first filter then read other columns prevented loading unnecessary data. These changes improved Spark SQL performance at ByteDance without changing jobs.

Making Data Timelier and More Reliable with Lakehouse Technology
Making Data Timelier and More Reliable with Lakehouse TechnologyMatei Zaharia Enterprise data architectures usually contain many systems—data lakes, message queues, and data warehouses—that data must pass through before it can be analyzed. Each transfer step between systems adds a delay and a potential source of errors. What if we could remove all these steps? In recent years, cloud storage and new open source systems have enabled a radically new architecture: the lakehouse, an ACID transactional layer over cloud storage that can provide streaming, management features, indexing, and high-performance access similar to a data warehouse. Thousands of organizations including the largest Internet companies are now using lakehouses to replace separate data lake, warehouse and streaming systems and deliver high-quality data faster internally. I’ll discuss the key trends and recent advances in this area based on Delta Lake, the most widely used open source lakehouse platform, which was developed at Databricks.

Os Gottfridoscon2007 DBSlayer is a middleware that allows web applications to access databases through HTTP and JSON. It provides a simple way to query databases by sending SQL statements in a JSON-formatted HTTP request and receiving the results of the query in the HTTP response also formatted in JSON. It aims to be independent, scalable, flexible and simple. Some features include connection pooling, load balancing queries across multiple databases, and automatic failover to alternate databases. It works by acting as an intermediary between web applications and databases, handling the network communication and database access transparently through its HTTP/JSON interface.

Leveraging the Web of Data: Managing, Analysing and Making Use of Linked Open...
Leveraging the Web of Data: Managing, Analysing and Making Use of Linked Open...Thomas Gottron The intensive growth of the Linked Open Data (LOD) Cloud has spawned a web of data where a multitude of data sources provides huge amounts of valuable information across different domains. Nowadays, when accessing and using Linked Data more and more often the challenging question is not so much whether there is relevant data available, but rather where it can be found, how it is structured and to make best use of it.
I this lecture I will start with giving a brief introduction to the concepts underlying LOD. Then I will focus on three aspects of current research:
(1) Managing Linked Data. Index structures play an important role for making use of the information in LOD cloud. I will give an overview of indexing approaches, present algorithms and discuss the ideas behind the index structures.
(2) Analysing Linked Data. I will present methods for analysing various aspects of LOD. From an information theoretic analysis for measuring structural redundancy, over formal concept analysis for identifying alternative declarative descriptions to a dynamics analysis for capturing the evolution of Linked Data sources.
(3) Making Use of Linked Data. Finally I will give a brief overview and outlook on where the presented techniques and approaches are of practical relevance in applications.

Instrumenting and Scaling Databases with Envoy
Instrumenting and Scaling Databases with EnvoyDaniel Hochman Every request to a database at Lyft is proxied by Envoy, providing complete visibility into the L3/L4 aspects of database interactions. This allows engineers to easily visualize changes to a database's load profile and pinpoint the root cause if necessary. Lyft has also open-sourced codecs for MongoDB, DynamoDB, and Redis. Protocol codecs in combination with custom filters yield benefits ranging from operation-level observability to horizontal scalability via sharding. Using Envoy for this purpose means that enhancements are implemented once and usable across a polyglot stack. The talk demonstrates Envoy's utility beyond traditional RPC service interactions in the network.

Synapse 2018 Guarding against failure in a hundred step pipelineCalvin French-Owen Control store (ctlstore) is a new infrastructure component that solves the "n+1 problem" of independent database failures bringing down a distributed system. It replicates control data from a system of record to local SQLite databases on each service node. Ctlstore loads data transactionally from the system of record using a loader, executive, and control data log. It then replicates changes to local databases using a reflector. Snapshots to object storage allow new instances to start up with the latest data. This approach provides high availability and fast querying of shared control data across many services.

Extending Analytic Reach - From The Warehouse to The Data Lake by Mike Limcaco
Extending Analytic Reach - From The Warehouse to The Data Lake by Mike LimcacoData Con LA Abstract:- The data marts and warehouses we work with often require us to think about how to scope our analytic questions based on the finite amount of storage allocated to these enterprise components. With new innovations in the cloud space, we can leverage the near-infinite storage capacities of Data Lake object storage and use this as foundational source that can be combined with online data in the warehouse. In this talk we present reference architecture patterns based on Amazon Redshift Spectrum - a new technology enabling you to run MPP Warehouse SQL queries against exabytes of data in a backing object store. With Redshift Spectrum, customers can extend the analytic reach of their SQL interactions to push beyond data stored on local disks in the data warehouse to query vast amounts of unstructured data in the Amazon S3 Data Lake-- without having to load or transform any data.
Named data networking. Basic Principle
Named data networking. Basic PrincipleМихаил Климарёв he Named Data Networking (NDN) project proposed an evolution of the IP architecture that generalizes the role of this thin waist, such that packets can name objects other than communication endpoints. More specifically, NDN changes the semantics of network service from delivering the packet to a given destination address to fetching data identified by a given name. The name in an NDN packet can name anything – an endpoint, a data chunk in a movie or a book, a command to turn on some lights, etc. The hope is that this conceptually simple change allows NDN networks to apply almost all of the Internet’s well-tested engineering properties to broader range of problems beyond end-to-end communications.

Building a fully managed stream processing platform on Flink at scale for Lin...Flink Forward Apache Flink is a distributed stream processing framework that allows users to process and analyze data in real-time. At LinkedIn, we developed a fully managed stream processing platform on Flink running on K8s to power hundreds of stream processing pipelines in production. This platform is the backbone for other infra systems like Search, Espresso (internal document store) and feature management etc. We provide a rich authoring and testing environment which allows users to create, test, and deploy their streaming jobs in a self-serve fashion within minutes. Users can focus on their business logic, leaving the Flink platform to take care of management aspects such as split deployment, resource provisioning, auto-scaling, job monitoring, alerting, failure recovery and much more. In this talk, we will introduce the overall platform architecture, highlight the unique value propositions that it brings to stream processing at LinkedIn and share the experiences and lessons we have learned.

Evening out the uneven: dealing with skew in FlinkFlink Forward Flink Forward San Francisco 2022.
When running Flink jobs, skew is a common problem that results in wasted resources and limited scalability. In the past years, we have helped our customers and users solve various skew-related issues in their Flink jobs or clusters. In this talk, we will present the different types of skew that users often run into: data skew, key skew, event time skew, state skew, and scheduling skew, and discuss solutions for each of them. We hope this will serve as a guideline to help you reduce skew in your Flink environment.

To improve Amazon Alexa experiences and support machine learning inference at scale, we built an automated end-to-end solution for incremental model building or fine-tuning machine learning models through continuous learning, continual learning, and/or semi-supervised active learning. Customer privacy is our top concern at Alexa, and as we build solutions, we face unique challenges when operating at scale such as supporting multiple applications with tens of thousands of transactions per second with several dependencies including near-real time inference endpoints at low latencies. Apache Flink helps us transform and discover metrics in near-real time in our solution. In this talk, we will cover the challenges that we faced, how we scale the infrastructure to meet the needs of ML teams across Alexa, and go into how we enable specific use cases that use Apache Flink on Amazon Kinesis Data Analytics to improve Alexa experiences to delight our customers while preserving their privacy.

Introducing BinarySortedMultiMap - A new Flink state primitive to boost your ...Flink Forward Flink Forward San Francisco 2022.
Probably everyone who has written stateful Apache Flink applications has used one of the fault-tolerant keyed state primitives ValueState, ListState, and MapState. With RocksDB, however, retrieving and updating items comes at an increased cost that you should be aware of. Sometimes, these may not be avoidable with the current API, e.g., for efficient event-time stream-sorting or streaming joins where you need to iterate one or two buffered streams in the right order. With FLIP-220, we are introducing a new state primitive: BinarySortedMultiMapState. This new form of state offers you to (a) efficiently store lists of values for a user-provided key, and (b) iterate keyed state in a well-defined sort order. Both features can be backed efficiently by RocksDB with a 2x performance improvement over the current workarounds. This talk will go into the details of the new API and its implementation, present how to use it in your application, and talk about the process of getting it into Flink.

Dynamically Scaling Data Streams across Multiple Kafka Clusters with Zero Fli...Flink Forward Flink Forward San Francisco 2022.
Flink consumers read from Kafka as a scalable, high throughput, and low latency data source. However, there are challenges in scaling out data streams where migration and multiple Kafka clusters are required. Thus, we introduced a new Kafka source to read sharded data across multiple Kafka clusters in a way that conforms well with elastic, dynamic, and reliable infrastructure. In this presentation, we will present the source design and how the solution increases application availability while reducing maintenance toil. Furthermore, we will describe how we extended the existing KafkaSource to provide mechanisms to read logical streams located on multiple clusters, to dynamically adapt to infrastructure changes, and to perform transparent cluster migrations and failover.

One sink to rule them all: Introducing the new Async SinkFlink Forward Flink Forward San Francisco 2022.
Next time you want to integrate with a new destination for a demo, concept or production application, the Async Sink framework will bootstrap development, allowing you to move quickly without compromise. In Flink 1.15 we introduced the Async Sink base (FLIP-171), with the goal to encapsulate common logic and allow developers to focus on the key integration code. The new framework handles things like request batching, buffering records, applying backpressure, retry strategies, and at least once semantics. It allows you to focus on your business logic, rather than spending time integrating with your downstream consumers. During the session we will dive deep into the internals to uncover how it works, why it was designed this way, and how to use it. We will code up a new sink from scratch and demonstrate how to quickly push data to a destination. At the end of this talk you will be ready to start implementing your own Flink sink using the new Async Sink framework.

Tuning Apache Kafka Connectors for Flink.pptxFlink Forward Flink Forward San Francisco 2022.
In normal situations, the default Kafka consumer and producer configuration options work well. But we all know life is not all roses and rainbows and in this session we’ll explore a few knobs that can save the day in atypical scenarios. First, we'll take a detailed look at the parameters available when reading from Kafka. We’ll inspect the params helping us to spot quickly an application lock or crash, the ones that can significantly improve the performance and the ones to touch with gloves since they could cause more harm than benefit. Moreover we’ll explore the partitioning options and discuss when diverging from the default strategy is needed. Next, we’ll discuss the Kafka Sink. After browsing the available options we'll then dive deep into understanding how to approach use cases like sinking enormous records, managing spikes, and handling small but frequent updates.. If you want to understand how to make your application survive when the sky is dark, this session is for you!

The Current State of Table API in 2022
The Current State of Table API in 2022Flink Forward Flink Forward San Francisco 2022.
The Table API is one of the most actively developed components of Flink in recent time. Inspired by databases and SQL, it encapsulates concepts many developers are familiar with. It can be used with both bounded and unbounded streams in a unified way. But from afar it can be difficult to keep track of what this API is capable of and how it relates to Flink's other APIs. In this talk, we will explore the current state of Table API. We will show how it can be used as a batch processor, a changelog processor, or a streaming ETL tool with many built-in functions and operators for deduplicating, joining, and aggregating data. By comparing it to the DataStream API we will highlight differences and elaborate on when to use which API. We will demonstrate hybrid pipelines in which both APIs interact with one another and contribute their unique strengths. Finally, we will take a look at some of the most recent additions as a first step to stateful upgrades.

Processing Semantically-Ordered Streams in Financial Services
Processing Semantically-Ordered Streams in Financial ServicesFlink Forward Flink Forward San Francisco 2022.
What if my data is already in order? Stream Processing has given us an elegant and powerful solution for running analytic queries and logic over high volumes of continuously arriving data. However, in both Apache Flink and Apache Beam, the notion of time-ordering is baked in at a very low level, making it difficult to express computations that are interested in a semantic-, rather than time-ordering of the data. In financial services, what often matters the most about the data moving between systems is not when the data was created, but in what order, to the extent that many institutions engineer a global sequencing over all data entering and produced by their systems to achieve complete determinism. How, then, can financial institutions and others best employ Stream Processing on streams of data that are already ordered? I will cover various techniques that can make this work, as well as seek input from the community on how Flink might be improved to better support these use-cases.

Tame the small files problem and optimize data layout for streaming ingestion...Flink Forward Flink Forward San Francisco 2022.
In modern data platform architectures, stream processing engines such as Apache Flink are used to ingest continuous streams of data into data lakes such as Apache Iceberg. Streaming ingestion to iceberg tables can suffer by two problems (1) small files problem that can hurt read performance (2) poor data clustering that can make file pruning less effective. To address those two problems, we propose adding a shuffling stage to the Flink Iceberg streaming writer. The shuffling stage can intelligently group data via bin packing or range partition. This can reduce the number of concurrent files that every task writes. It can also improve data clustering. In this talk, we will explain the motivations in details and dive into the design of the shuffling stage. We will also share the evaluation results that demonstrate the effectiveness of smart shuffling.

Batch Processing at Scale with Flink & IcebergFlink Forward Flink Forward San Francisco 2022.
Goldman Sachs's Data Lake platform serves as the firm's centralized data platform, ingesting 140K (and growing!) batches per day of Datasets of varying shape and size. Powered by Flink and using metadata configured by platform users, ingestion applications are generated dynamically at runtime to extract, transform, and load data into centralized storage where it is then exported to warehousing solutions such as Sybase IQ, Snowflake, and Amazon Redshift. Data Latency is one of many key considerations as producers and consumers have their own commitments to satisfy. Consumers range from people/systems issuing queries, to applications using engines like Spark, Hive, and Presto to transform data into refined Datasets. Apache Iceberg allows our applications to not only benefit from consistency guarantees important when running on eventually consistent storage like S3, but also allows us the opportunity to improve our batch processing patterns with its scalability-focused features.

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
