Data lakes have become a key ingredient in the data architecture of most companies. In the cloud, object storage systems such as S3 and ADLS make it easier than ever to operate a data lake. However, there are still a number of key challenges when it comes to building a cloud-based data lake:

  • Most data in the cloud doesn’t start in S3 and ADLS. Instead, it’s stored in a variety of data sources, ranging from relational databases like Amazon RDS and Azure SQL DB, to NoSQL databases like MongoDB and Elasticsearch. Logs often start their life in a data pipeline layer such as Kafka.
  • The data needs to be processed, explored and analyzed using a variety of engines, including Spark, Impala, Athena and Dremio. While an on-premise data lake is static, a cloud data lake enables these engines to run independently, on a common storage layer, with their own individual lifecycle and scale.
  • S3 and ADLS are typically slower than HDFS. This introduces challenges for real-time workloads.

In this talk we describe how companies are building data lakes in the cloud using S3 and ADLS as storage layers, while leveraging multiple processing engines to address various needs including batch processing, ad-hoc data exploration, reporting and ML/AI. In addition to exploring best practices, we provide several real-world examples from different industries.

In addition, we discuss the significance of Apache Arrow to the future of the heterogeneous data lake. Arrow is now downloaded 2.5 million times per month, up 100x in the last year, and is a foundational component in dozens of open source technologies such as Pandas, R, Spark and Dremio. With the introduction of Arrow Flight, it will soon be possible to exchange Big Data data between various distributed systems in the data lake, thereby unlocking additional use cases and dramatically increasing the performance of data lake workloads.

Prerequisite knowledge

Basic Linux and SQL skills are beneficial in order to follow the examples.
