Building Spatial Applications with Apache Spark and CARTO

Building Spatial Applications with Apache Spark and CARTO

2022-07-19 Watch
video

CARTO’s Spatial Extension provides the fundamental building blocks for Location Intelligence in Databricks. Many of the largest organizations using CARTO leverage Databricks for their analytics. Customers very often build custom spatial applications that simplify either a spatial analysis use case or provide a more direct interface to access business intelligence or information. CARTO facilitates the creation of these apps with a complete set of development libraries and APIs. For visualization, CARTO makes use of the powerful deck.gl visualization library. You utilize CARTO Builder to design your maps and perform analytics using Spatial SQL similar to PostGIS, but with the scalability of Apache Spark and then you reference them in your code. CARTO will handle visualizing large datasets, updating the maps, and everything in between. In this talk we will walk you through the process to build spatial applications with CARTO hosted in Apache Spark.

Coral and Transport Portable SQL and UDFs for the Interoperability of Spark and Other Engines

Coral and Transport Portable SQL and UDFs for the Interoperability of Spark and Other Engines

2022-07-19 Watch
video

In this talk, we present two open source projects, Coral and Transport, that enable deep SQL and UDF interoperability between Spark and other engines, such as Trino and Hive. Coral is a SQL analysis, rewrite, and translation engine that enables compute engines to interoperate and analyze different SQL dialects and plans, through the conversion to a common relational algebraic intermediate representation. Transport is a UDF framework that enables users to write UDFs against a single API but execute them as native UDFs of multiple engines, such as Spark, Trino, and Hive. Further, we discuss how LinkedIn leverages Coral and Transport, and present a production use case for accessing views of other engines in Spark as well as enhancing Spark DataFrame and Dataset view schema. We discuss other potential applications such as automatic data governance and data obfuscation, query optimization, materialized view selection, incremental compute, and data source SQL and UDF communication.

Spark Data Source V2 Performance Improvement: Aggregate Push Down

Spark Data Source V2 Performance Improvement: Aggregate Push Down

2022-07-19 Watch
video

Spark applications often need to query external data sources such as file-based data sources or relational data sources. In order to do this, Spark provides Data Source APIs to access structured data through Spark SQL.

Data Source APIs have optimization rules such as filter push down and column pruning to reduce the amount of data that needs to be processed to improve query performance. As part of our ongoing project to provide generic Data Source V2 push down APIs, we have introduced partial aggregate push down, which significantly speeds up spark jobs by dramatically reducing the amount of data transferred between data sources and Spark. We have implemented aggregate push down in both JDBC and parquet.

Data collection, preprocessing, feature engineering are the fundamental steps in any Machine Learning Pipeline. After feature engineering, being able to parallelize training on multiple low cost machines helps to reduce cost and time both. And, then being able to train models in a distributed manner speeds up Hyperparameter Tuning. How can we unify these stages of ML Pipeline in one unified distributed training platform together? And that too on Kubernetes?

Our ML platform is completely based on Kubernetes because of its scalability and rapid bootstrapping time of resources. In this talk we will demonstrate how Lyft uses Spark on Kubernetes, Fugue (our home grown unifying compute abstraction layer) to design a holistic end to end ML Pipeline system for distributed feature engineering, training & prediction experience for our customers on our ML Platform on top of Spark on K8s. We will also do a deep dive to show how we are abstracting and hiding infrastructure complexities so that our Data Scientists and Research Scientist can focus only on the business logic for their models through simple pythonic APIs and SQL. We let the users focus on ''what to do'' and the platform takes care of ''how to do''. We will share our challenges, learning and the fun we had while implementing. Using Spark on K8s have helped us achieve large scale data processing with 90% less cost and at times bringing down processing time from 2 hours to less than 20 mins.

It is known that applications, which heavily use Spark SQL union() operation, cause performance problems. The union() operation combines multiple rows into one table. When union() operation merges many Dataframes, the size of the generated Spark SQL planning tree will be huge while the Spark SQL code is small. The huge planning tree may lead to performance problems. This talk reviews performance problems from the Spark SQL planning perspective and explains how to avoid the performance issues with common practices.

dbt has done a great job of building an elegant, common interface between data engineers and data analysts: uniting on SQL. As the data industry evolves, there's plenty of pain and room to grow in building that interface between data scientists and data analysts. There isn't a good answer for when things go wrong in the machine learning arena: should the data analyst own fine-tuning the pre-processing data(think: prepping transformed data even more for machine learning models to better work with the data). Should we increase the SQL surface area to build ML models or should we leave that to non-SQL interfaces(python/scala/etc.)? Does this have to be an either/or future? Whatever the interface evolves into, it must center people, create a low bar and high ceiling, and focus on outcomes and not the mystique of features/tools behind a learning curve.

If you’ve ever had to delete a set of records for regulatory compliance, update a set of records to fix an issue in the ingestion pipeline, or apply changes in a transaction log to a fact table, you know that row-level operations are becoming critical for modern data lake workflows. This talk will focus on some of the upcoming features in Spark 3.3 that will enable execution of row-level operations and allow Spark to only pass to connectors what rows to delete, update, or insert. As a result, data sources won’t have to provide low-level SQL extensions for Spark and will be able to benefit from a scalable built-in implementation that works across all connectors. The presentation will be useful for data source developers as well as data engineers and analysts interested in performing DELETE, UPDATE, MERGE operations in Spark.

Enable Production ML with Databricks Feature Store

Enable Production ML with Databricks Feature Store

2022-07-19 Watch

Productionalizing ML models is hard. In fact, very few ML projects make it to production, and one of the hardest problems is data! Most AI platforms are disconnected from the data platform, making it challenging to keep features constantly updated and available in real-time. Offline/online skew prevents models from being used in real-time or, worse, introduces bugs and biases in production. Building systems to enable real-time inference requires valuable production engineering resources. As a result of these challenges, most ML models do not see the light of day.

Learn how you can simplify production ML using Databricks Feature Store, the first feature store built on the data lakehouse. Data sources for features are drawn from a central data lakehouse, and the feature tables themselves are tables in the lakehouse, accessible in Spark and SQL for both machine learning and analytics use cases. Features, data pipelines, source data, and models can all be co-governed in a central platform. Feature Store is seamlessly integrated with Apache Spark™, enabling automatic lineage tracking, and with MLflow, enabling models to look up feature values at inference time automatically. See these capabilities in action and how you can use it for your ML projects.

Business Intelligence (BI) tools such as Tableau and Microsoft Power BI are notoriously slow at extracting large query results from traditional data warehouses because they typically fetch the data in a single thread through a SQL endpoint that becomes a data transfer bottleneck. Data analysts can connect their BI tools to Databricks SQL endpoints to query data in tables through an ODBC/JDBC protocol integrated in our Simba drivers. With Cloud Fetch, which we released in Databricks Runtime 8.3 and Simba ODBC 2.6.17 driver, we introduce a new mechanism for fetching data in parallel via cloud storage such as AWS S3 and Azure Data Lake Storage to bring the data faster to BI tools. In our experiments using Cloud Fetch, we observed a 10x speed-up in extract performance due to parallelism.
