Examples of column-oriented formats include Apache ORC, [3] Apache Parquet, [4] Apache Arrow, [5] formats used by BigQuery, Amazon Redshift and Snowflake. Predominant examples of row-oriented formats include CSV, formats used in most relational databases , the in-memory format of Apache Spark , and Apache Avro .
Avro is a row-oriented remote procedure call and data serialization framework developed within Apache's Hadoop project. It uses JSON for defining data types and protocols , and serializes data in a compact binary format.
The open-source project to build Apache Parquet began as a joint effort between Twitter [3] and Cloudera. [4] Parquet was designed as an improvement on the Trevni columnar storage format created by Doug Cutting, the creator of Hadoop. The first version, Apache Parquet 1.0, was released in July 2013. Since April 27, 2015, Apache Parquet has been ...
Flow diagram. In computing, serialization (or serialisation, also referred to as pickling in Python) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different computer ...
Reads Hadoop file formats, including text, LZO, SequenceFile, Avro, RCFile, Parquet and ORC; Supports Hadoop security (Kerberos authentication, Ldap), Fine-grained, role-based authorization with Apache Sentry and Apache ranger; Uses metadata, ODBC driver, and SQL syntax from Apache Hive.
Parquet: a general-purpose columnar storage format; PDFBox: Java based PDF library (reading, text extraction, manipulation, viewer) Mod_perl: module that integrates the Perl interpreter into Apache server; Pekko: toolkit and an ecosystem for building highly concurrent, distributed, reactive and resilient applications for Java and Scala [9]
Trino is an open-source distributed SQL query engine designed to query large data sets distributed over one or more heterogeneous data sources. [1] Trino can query data lakes that contain a variety of file formats such as simple row-oriented CSV and JSON data files to more performant open column-oriented data file formats like ORC or Parquet [2] [3] residing on different storage systems like ...
