Apache Druid is a real-time analytics database and distributed columnar time-series store designed for sub-second analytical queries. It functions as a data platform featuring a distributed SQL query engine and a real-time data ingestion system for moving historical and streaming data from external sources. The system is distinguished by its ability to provide low-latency analytics under high concurrency to power operational dashboards. It implements a Kerberos-secured environment for user authentication and employs a shared-nothing cluster architecture to enable horizontal scaling. The plat

Perspective is a columnar data analytics engine and high-performance visualization component powered by WebAssembly. It provides a system for analyzing and visualizing large or streaming datasets through interactive data grids and charts, utilizing a compiled binary to achieve near-native performance within the browser. The project distinguishes itself through a WebSocket-based data streaming interface and deep Apache Arrow integration, which minimize memory overhead when synchronizing tables between servers and clients. It acts as a remote query proxy capable of translating visualization con

FerretDB is an open-source database emulator and protocol translator that mimics a MongoDB environment to support existing drivers and client tools on a relational backend. It functions as a stateless database proxy that converts binary wire protocol messages into SQL statements, allowing a relational engine to handle document-oriented requests. The project serves as a migration tool for moving applications from MongoDB to PostgreSQL without rewriting queries or changing client drivers. It achieves this by using PostgreSQL as a document store, storing and querying BSON documents through a tra

Perspective is a columnar data analytics library and streaming data visualization engine. It provides an interactive data grid component and notebook analytics widgets designed for processing high-volume data and rendering interactive charts and grids. The system utilizes a high-performance query engine to enable real-time data analysis and streaming dataset visualization. It supports the creation of customizable dashboards and reports that update automatically as new data arrives without requiring full dataset reloads. The project covers large-scale dataset analytics through a schema-driven

This project provides a SQL interface for Elasticsearch, serving as a translator and database layer that allows users to retrieve, filter, and manipulate indices using structured query language. It functions by converting standard SQL statements into the native JSON query language used by the search engine. The system includes a geospatial SQL engine for executing location-based searches and distance calculations. It also features a query debugger used to visualize the translation process from SQL to search engine request bodies to verify the logic and accuracy of data retrieval. The capabil

Calcite ist ein Framework zum Parsen, Optimieren und Übersetzen von SQL-Abfragen in relationale Algebra für die Ausführung über verschiedene Datenquellen hinweg. Es fungiert als Cross-Source-Query-Engine, SQL-Parsing-Bibliothek und Optimierer für relationale Algebra. Das Projekt bietet eine kostenbasierte Optimierungs-Engine, die logische Abfragepläne mittels pluggbarer Regeln in effiziente physische Ausführungspläne umwandelt. Es nutzt Übersetzungsadapter, um Standard-SQL-Anfragen in die nativen Formate externer Datenbanken und Messaging-Systeme zu konvertieren, was Datenföderation über heterogene Speichersysteme hinweg ermöglicht. Das System deckt den gesamten Abfrage-Lebenszyklus ab, einschließlich SQL-Parsing und Validierung gegen Schemata, die Übersetzung von Ausdrücken in algebraische Operatoren sowie die Auswahl effizienter Ausführungspläne. Es enthält zudem ein Command-Line-Interface zum Ausführen von Abfragen und Verwalten von Verbindungen zu Datenquellen.
