This talk is a story, using examples in Python and pySpark, about testing ETL pipelines efficiently. I won’t try to convince you that you need unit tests or automated tests – that’s up to you. If you do have unit tests for your ETL pipelines, or if you want them, it can be useful to make sure you aren’t testing more than you need.

I’ll be describing how a practical (non-pyramid shaped) heuristic helps me efficiently cover edge cases and unexpected bugs in my code by ensuring I test only the code needed for the feature I’m building.

In this session we’ll present Mosaic, a new Databricks Labs project with a geospatial flavour.

Mosaic provides users of Spark and Databricks with a unified framework for distributing geospatial analytics. Users can choose to employ existing Java-based tools such as JTS or Esri's Geometry API for Java and Mosaic will handle the task of parallelizing these tools' operations: e.g. efficiently reading and writing geospatial data and performing spatial functions on geometries. Mosaic helps users scale these operations by providing spatial indexing capabilities (using, for example, Uber's H3 library) and advanced techniques for optimising common point-in-polygon and polygon-polygon intersection operations.

The development of Mosaic builds upon techniques developed with Ordnance Survey (the central hub for geospatial data across UK Government) and described in this blog post: https://databricks.com/blog/2021/10/11/efficient-point-in-polygon-joins-via-pyspark-and-bng-geospatial-indexing.html

PySpark has rapidly evolved with the momentum of Project Zen introduced in Apache Spark 3.0. We improved error messages, added type hints for autocompletion, implemented visualization, etc. Most importantly, Pandas API on Spark was introduced from Apache Spark 3.2 which exposes the pandas API that runs on Apache Spark, and the Pandas API on Spark has gained a lot of popularity.

In Apache Spark 3.3, the effort of Project Zen continued and PySpark has many cool changes such as more API coverage & faster default index in Pandas API on Spark, datetime.timedelta support, new PyArrow batch interface, better autocompletion, Python & Pandas UDF profiler and new error classification.

In this talk, we will introduce what is new in PySpark at Apache Spark 3.3, and what is next beyond Apache Spark 3.3 with the current effort and roadmap in PySpark.

Many enterprises have built their own machine learning platforms in the cloud using Databricks, e.g. Humana FlorenceAI. In order to effectively drive the adoption of predictive models in daily business operations, data scientists and business teams need to work closely to make sure they serve the consumer needs in compliance with regulatory rules. Model interpretability is key. In this talk, we would like to share an explainable AI algorithm developed at Humana, X-FIPE, eXtended Feature Impact for Prediction Explanation.

X-FIPE is a top-driver algorithm to calculate feature importance for any machine learning predictive models, whether it is Python or PySpark, at a local level. Instead of showing the feature importance on a population level, it can find the top drivers for each observation or member. These top drivers could differ widely from one member to another member in the population. it not only helps explain the predictive model, but also offer users actionable insights.

Compared with widely used algorithms, e.g. LIME, SHAP, and FIPE, X-FIPE improves the time complexity from linear O(n) to logarithmic O(log(n)), where n is the number of used model features. Also, we discovered the connection between X-FIPE value and Shapley value -- X-FIPE a first order approximation of Shapley value. Our observation shows that the most contribution of Shapley value of a feature comes from the marginal contribution when it is first added and when it is last removed from the full features. This is why the X-FIPE keeps enough accuracy and also reduces the computation.

Hopefully this talk will provide you a path forward to include explainable AI into your machine learning workflows, you are encouraged to try out and contribute to our open source Python package xfipe soon to come.

Find out how Gousto is developing its data pipelines at scale in a repeatable manner. At Gousto, we’ve developed Goustospark - a wrapper around pyspark that allows us to quickly and easily build data pipelines that are deployed into our Databricks environment.

This wrapper abstracts repetitive components of all data pipelines such as spark configurations and metastore interactions. This allows a developer to simply specify the blueprints of the pipeline before turning their attention to more pressing issues, such as data quality and data governance, whilst enjoying a high level of performance and reliability.

In this session we will deep dive into the design patterns we followed, some unique approaches we’ve taken on how we structure pipelines and show a live demo of implementing a new spark streaming pipeline in Databricks from scratch. We will even share some example python code and snippets to help you build your own.

The logic in your data is the heartbeat of your organization’s reports, analytics, dashboards and applications. But that logic is often trapped in antiquated technologies that can’t take advantage of the massive scalability in the Databricks Lakehouse.

In this session BladeBridge will show how to automate the conversion of this metadata and code into Databricks PySpark and DBSQL. BladeBridge will demonstrate the flexibility of configuring for N legacy technologies to facilitate an automated path for not just a single modernization project but a factory approach for corporate wide modernization.

BladeBridge will also present how you can empirically size your migration project to determine the level of effort required.

In recent years, latest privacy laws & regulations bring a fundamental shift in the protection of data and privacy, placing new challenges to data applications. To resolve these privacy & security challenges in big data ecosystem without impacting existing applications, several hardware TEE (Trusted Execution Environment) solutions have been proposed for Apache Spark, e.g., PySpark with Scone and Opaque etc. However, to the best of our knowledge, none of them provide full protection to data pipelines in Spark applications. An adversary may still get sensitive information from unprotected components and stages. Furthermore, some of them greatly narrowed supported applications, e.g., only support SparkSQL. In this presentation, we will present a new PPMLA (privacy preserving machine learning and analytics) solution built on top of Apache Spark, BigDL, Occlum and Intel SGX. It ensures all spark components and pipelines are fully protected by Intel SGX, and existing Spark applications written in Scala, Java or Python can be migrated into our platform without any code change. We will demonstrate how to build distributed end-to-end SparkML/SparkSQL workloads with our solution on untrusted cloud environment and share real-world use cases for PPMLA.

Summary The scale and complexity of the systems that we build to satisfy business requirements is increasing as the available tools become more sophisticated. In order to bridge the gap between legacy infrastructure and evolving use cases it is necessary to create a unifying set of components. In this episode Dipti Borkar explains how the emerging category of data orchestration tools fills this need, some of the existing projects that fit in this space, and some of the ways that they can work together to simplify projects such as cloud migration and hybrid cloud environments. It is always useful to get a broad view of new trends in the industry and this was a helpful perspective on the need to provide mechanisms to decouple physical storage from computing capacity.
