  • Uwe L Korn - Efficient and portable DataFrame storage with Apache Parquet

    Filmed at PyData London 2017 www.pydata.org Description Apache Parquet is the most used columnar data format in the big data processing space and recently gained Pandas support. It leverages various techniques to store data in a CPU and I/O efficient way and provides capabilities to push-down queries to the I/O layer. In this talk, it is shown how to use it in Python, detail its structure and present the portable usage with other tools. Abstract Since its creation in 2013, Apache Parquet has risen to be the most widely used binary columnar storage format in the big data processing space. While supporting basic attributes of a columnar format like reading a subset of columns, it also leverages techniques to store the data efficiently while providing fast access.

In this talk, it is shown how to use it in Python, detail its structure and present the portable usage with other tools. Abstract Since its creation in 2013, Apache Parquet has risen to be the most widely used binary columnar storage format in the big data processing space. While supporting basic attributes of a columnar format like reading a subset of columns, it also leverages techniques to store the data efficiently while providing fast access. In addition the format is structured in such a fashion that when supplied to a query engine, Parquet provides indexing hints and statistics to quickly skip over chunks of irrelevant data. In recent months, efficient implementations to load and store Parquet files in Python became available, bringing the efficiency of the format to Pandas DataFrames. While this provides a new option to store DataFrames, it especially allows us to share data between Pandas and a lot of other popular systems like Apache Spark or Apache Impala. In this talk we will show the improvements that Parquet bring performance-wise but also will highlight important aspects of the format that make it portable and efficient for queries on large amount of data. As not all features are yet available in Python, an overview of the upcoming Python-specific improvements and how the Parquet format will be extended in general is given at the end of the talk. PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States. PyData provides a forum for the international community of users and developers of data analysis tools to share ideas and learn from each other. The global PyData network promotes discussion of best practices, new approaches, and emerging technologies for data management, processing, analytics, and visualization. PyData communities approach data science using many languages, including (but not limited to) Python, Julia, and R. We aim to be an accessible, community-driven conference, with novice to advanced level presentations. PyData tutorials and talks bring attendees the latest project features along with cutting-edge use cases.

As we move from more general solution to specific optimization techniques, the level of performance impact grows. This talk will discuss how layering in-memory caching, columnar storage and relational caching can combine to provide a substantial improvement in overall data science and analytical workloads. It will include a detailed overview of how you can use Apache Arrow, Calcite and Parquet to achieve multiple magnitudes improvement in performance over what is currently possible. We'll start by talking about in-memory caches and the difference between block-based and data-aware caching strategies. We'll discuss the deployment design of this type of solution as well as cover the strengths of each. There will also be a discussion of the relationship of security and predicate application in these scenarios. Then we'll go into detail about how columnar storage formats can further enhance performance by minimizing read time, optimizing for vectorized in-memory processing and powerful compression techniques. Lastly, we'll introduce a much more advanced way to speed access to data called relational caching. Relational caching builds a cache on columnar in-memory caching techniques but also includes a full comprehension of how data is being used and how different forms of data relate to each other. This will include leveraging multiple sorting and partitioning strategies as well as maintaining multiple related derivations of data for different types of access patterns. As part of this and we also cover approaches to data ttl, relational cache consistency and several different approaches to data mutation and real-time updates.
