Traditional cybersecurity Security Information and Event Management (SIEM) ways do not scale well for data sources with 30TiB per day, leading HSBC to create a Cybersecurity Lakehouse with Delta and Spark. Creating a platform to overcome several conventional technical constraints, the limitation in the amount of data for long-term analytics available in traditional platforms and query languages is difficult to scale and time-consuming to run. In this talk, we’ll learn how to implement (or actually reverse-engineer) a language with Scala and translate it into what Apache Spark understands, the Catalyst engine. We’ll guide you through the technical journey of building equivalents of a query language into Spark. We’ll learn how HSBC business benefited from this cutting-edge innovation, like decreasing time and resources for Cyber data processing migration, improving Cyber threat Incident Response, and fast onboarding of HSBC Cyber Analysts on Spark with Cybersecurity Lakehouse platform.

DoorDash was using a data warehouse but found that they needed more data transparency, lower costs, and the ability to handle streaming data as well as batch data. With an engineering team rooted in big data backgrounds at Uber and LinkedIn, they moved to a Lakehouse architecture intuitively, without knowing about the term. In this session, learn more about how they arrived at that architecture, the process of making the move, and the results they have seen. While addressing both data analysts and data scientists from their lakehouse, this session will focus on their machine learning operations, and how their efficiencies are enabling them to tackle more advanced use cases such as NLP and image classification.

You’ve successfully built your data lakehouse. Congratulations! But what happens when your operational data stores, streaming systems like Apache Kafka or data ingestion systems produce bad data into the lakehouse? Can you be proactive when it comes to preventing bad data from affecting your business? How can you take advantage of automation to ensure that raw data assets become well maintained data products (clear ownership, documentation and sensitivity classification) without requiring people to do redundant work across operational, ingestion and lakehouse systems? How do you get live and historical visibility into your entire data ecosystem (schemas, pipelines, data lineage, models, features and dashboards) within and across your production services, ingestion pipelines and data lakehouse? Data engineers struggle with data quality and data governance issues constantly interrupting their day and limiting their upside impact on the business.

In this talk, we will share how data engineers from our 3K+ strong DataHub community are using DataHub to track lineage, understand data quality, and prevent failures from impacting their important dashboards, ML models and features. The talk will include details of how DataHub extracts lineage automatically from Spark, schema and statistics from Delta Lake and shift-left strategies for developer-led governance.

A common pattern in Data Lake and Lakehouse design is structuring data into zones, with Bronze, Silver and Gold being typical labels. Each zone is suitable for different workloads and different consumers: for instance, machine learning algorithms typically process against Bronze or Silver, while analytic dashboards often query Gold. This prompts the question: which layer is best suited for applying data quality rules and actions? Our answer: all of them.

In this session, we’ll expand on our answer by describing the purposes of the different zones, and mapping the categories of data quality relevant for each by assessing its qualitative requirements. We’ll describe Data Enrichment: the practice of making observed anomalies available as inputs to downstream data pipelines, and provide recommendations for when to merely alert, when to quarantine data, when to halt pipelines, and when to apply automated corrective actions.

Lakehouses like Databricks’ Delta Lake are becoming the central brain for all data systems. But Lakehouses are only one component of the data stack. There are many building blocks required for tackling data needs, including data integrations, data transformation, data quality, observability, orchestration etc.

In this session, we will present how open source powers companies' approach to building a modern data stack. We will talk about technologies like Airbyte, Airflow, dbt, Preset, and how to connect them in order to build a customized and extensible data platform centered around Databricks.

Within Wehkamp we required a uniform way to provide reliable and on time data to the business, while making this access compliant with GDPR. Unlocking all the data sources that we have scattered across the company and democratize the data access was of the utmost importance, allowing us to empower the business with more, better and faster data.

Focusing on open source technologies, we've built a data platform almost from the ground up that focuses on 3 levels of data curation - bronze, silver and gold - which follows the LakeHouse Architecture. The ingestion into bronze is where the PII fields are pseudonymized, making the use of the data within the delta lake compliant and, since there is no visible user data, it means everyone can use the entire delta lake for exploration and new use cases. Naturally, specific teams are allowed to see some user data that is necessary for their use cases. Besides the standard architecture, we've developed a library that allows us to ingest new data sources by adding a JSON config file with the characteristics. This combined with the ACID transactions that delta provides and the efficient Structured Stream provided through Auto Loader has allowed a small team to maintain 100+ streams with insignificant downtime.

Some other components of this platform are the following: - Alerting to Slack - Data quality checks - CI/CD - Stream processing with the delta engine

The feedback so far has been encouraging, as more and more teams across the company are starting to use the new platform and taking advantage of all its perks. It is still a long time until we get to turn off some of the components of the old data platform, but it has come a long way.

At Spark Data & AI 2021, We presented the use case around Privacy in an Insurance Landscape using Privacera. Scaling Privacy in a Spark Ecosystem (https://www.youtube.com/watch?v=cjJEMlNcg5k). In one year, the concept of privacy and security have taken off as a major need to solve and the ability to embed this into business process to empower data democratization has become mandatory. The concept that data is a product is now commonplace and that ability to rapidly innovate those products hinges on the ability to balance a dual mandate. One mandate: Move Fast. Second Mandate: Manage Privacy and Security. How do we make this happen? Let's dig into the real details and experiences and show the blueprint for success.

Every industry must comply with some form of compliance or data security in order to operate. As data becomes more mission critical to the organization, so does the need to protect and secure it.

Public Sector organizations are responsible for securing sensitive data sets and complying with regulatory programs such as HIPAA, FedRAMP, and StateRAMP.

This does not come as a surprise given the many different attacks targeted at the industry and the extremely sensitive nature of the large volumes of data stored and analyzed. For a product owner or DBA, this can be extremely overwhelming with a security team issuing more restrictions and data access becoming more of a common request among business users. It can be difficult finding an effective governance model to democratize data while also managing compliance across your hybrid estate.

In this session, we will discuss challenges faced in the public sector when expanding to AWS cloud. We will review best practices for managing access and data integrity for a cloud-based data lakehouse with Databricks, and discuss recommended approaches for securing your AWS Cloud environment. We will highlight ways to enable compliance by developing a continuous monitoring strategy and providing tips for implementation of defense in depth. This guide will provide critical questions to ask, an overall strategy, and specific recommendations to serve all security leaders and data engineers in the Public Sector.

This talk is intended to educate on security design considerations when extending your data warehouse to the cloud. This guidance is expected to grow and evolve as new standards and offerings emerge for local, state, and federal government.

This presentation will first introduce the use case, which generates the price adjustments based on the network effect, and the corresponding model relies on the 108 near real-time features computed by Flink pipelines with the raw demand and supply events. Here is the simplified computation logic:

-The pipelines need to process the raw real-time events at the rate of 300k/s including both demand and supply -Each event needs to be computed on the geospatial, temporal and other dimensions -Each event contributes to the computation on the original hexagon and the 1K+ neighbours due to the fan-out effect of Kring smooth -Each event contributions to the aggregation on multiple window sizes up to 32 minutes, sliding by 1 minute, or 63 windows in total

Next the presentation will briefly go through the DAG of the Flink pipeline before optimization and the issues we faced: the pipeline could not run stably due to OOM and backpressure. The presentation will discuss how to optimize a streaming pipeline with the generic performance tuning framework, which focuses on three areas: Network, CPU and Memory, and five domains: Parallelism, Partition, Remote Call, Algorithm and Garbage Collector. The presentation will also show some example techniques being applied onto the pipelines by following the performance tuning framework.

Then the presentation will discuss one particular optimization technique: Customized Sliding Window.

Powering machine learning models with near real-time features can be quite challenging, due to computation logic complexity, write throughput, serving SLA, etc. In this talk, we have introduced some of the problems that we faced and our solutions to them, in the hope of aiding our peers in similar use cases.
