    Julien Le Dem discusses Parquet, a columnar file format for Hadoop. Performance and compression benefits of using columnar storage formats for storing and processing large amounts of data are well documented in academic literature as well as several commercial analytical databases. Parquet supports deeply nested structures, efficient encoding and column compression schemes, and is designed to be compatible with a variety of higher-level type systems. Its integration in most of the Hadoop processing frameworks (Impala, Hive, Pig, Cascading, Crunch, Scalding, Spark, ...) and serialization models (Thrift, Avro, Protocol Buffers, ...) makes it easy to use in existing ETL and processing pipelines, while giving flexibility of choice on the query engine (whether in Java or C++).

  • 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 addition the format is ...

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.

Recorded at DataEngConf SF '17 You have your Hadoop cluster, and you are ready to fill it up with data, but wait: Which format should you use to store your data? Should you store it in Plain Text, Sequence File, Avro, or Parquet? (And should you compress it?) HDFS or Block/Object Store? Which query engine? This talk will take a closer look at some of the trade-offs, and will cover the How, Why, and When of choosing one format over another. Picking your distribution and platform is just the first decision of many you need to make in order to create a successful data ecosystem. In addition to things like replication factor and node configuration, the choice of file format can have a profound impact on cluster performance. Each of the data formats have different strengths and weaknesses, depending on how you want to store and retrieve your data. For instance, we have observed performance differences on the order of 25x between Parquet and Plain Text files for certain workloads. However, it isn’t the case that one is always better than the others. Adding to the data formats selection is which query engine works best for the data format & workload. Oh lets not forget the question: “Do I store that in HDFS or a block/object store?” This talk will take a closer look at some of these trade-offs. Attendees will learn, based on a few real world use cases, the How, Why, and When of choosing one format over another (and will your choice of query engine affect this.). Covering the four major data formats (Plain Text, Sequence Files, Avro, and Parquet) we will provide insight into what they are and how to best use and store them in HDFS or a block/object store.
