AlaSQL/alasql
7,278GitHub पर देखेंAlaSQL is a JavaScript SQL database engine that allows for the filtering, grouping, and joining of in-memory object arrays and JSON data. It functions as an in-memory SQL database and client-side data processor, enabling the execution of SQL statements against JavaScript arrays and external data sources in both browser and server environments. The project serves as a universal data query tool capable of performing relational joins across diverse sources, such as merging Google Spreadsheets, SQLite files, and remote APIs into a single result set. It also acts as an IndexedDB SQL wrapper, allow
Allows the implementation of multi-stage user-defined aggregation functions to summarize grouped data.

apache/pinot
6,098GitHub पर देखेंPinot is a distributed, columnar analytical database designed for high-concurrency, low-latency query processing. It functions as a real-time OLAP datastore, enabling interactive, user-facing analytics by ingesting and querying massive datasets from both streaming and batch sources. The system architecture relies on a centralized controller for cluster coordination and a distributed segment-based storage model to ensure horizontal scalability. The platform distinguishes itself through a hybrid ingestion pipeline that unifies real-time event streams and historical batch data into a single quer
Allows configuration of aggregation functions to compute results directly within the index.

apache/hive
6,012GitHub पर देखेंApache Hive is a SQL-on-Hadoop data warehouse that enables querying and managing petabytes of data stored in distributed storage such as HDFS and cloud storage services. It provides a familiar SQL interface for batch analytics and reporting, supported by a core set of components including the HiveServer2 Thrift service for remote query execution, the Hive Metastore Service for central metadata management, the Hive ACID Transaction Engine for concurrent read-write operations, and the Hive LLAP Interactive Engine for low-latency analytical processing. The WebHCat REST API offers an HTTP interfac

ArroyoSystems/arroyo
4,819GitHub पर देखेंArroyo is a high-performance stream processing platform built in Rust. It executes continuous SQL queries on streaming data with event-time semantics, enabling accurate windowed aggregations, joins, and stateful computations on unbounded event streams. The platform uses native Rust execution for high throughput and low latency, with periodic checkpointing for exactly-once fault tolerance and horizontal scaling across distributed workers. The system integrates deeply with Kafka for reading and writing topics with exactly-once delivery and supports change data capture (CDC) from MySQL and Postg
Extends SQL with custom aggregation functions written in Rust for stateful stream processing.

4,607GitHub पर देखेंH2 Java में लिखा गया एक JDBC-अनुपालन रिलेशनल डेटाबेस मैनेजमेंट सिस्टम है। यह एक एम्बेड करने योग्य SQL डेटाबेस के रूप में कार्य करता है जो नेटवर्क लेटेंसी को हटाने के लिए सीधे एप्लिकेशन प्रोसेस के भीतर चल सकता है, या उच्च-प्रदर्शन वाले वोलेटाइल स्टोरेज के लिए इन-मेमोरी डेटाबेस के रूप में कार्य कर सकता है। इसमें SQL कमांड निष्पादित करने और स्कीमा प्रबंधित करने के लिए एक वेब-आधारित कंसोल भी शामिल है। सिस्टम को इसके लचीले डिप्लॉयमेंट मोड द्वारा पहचाना जाता है, जिसमें रिमोट TCP/IP एक्सेस के लिए स्टैंडअलोन सर्वर मोड और स्थानीय व रिमोट कनेक्टिविटी के लिए मिक्स्ड मोड शामिल है। इसमें एक डायलेक्ट एमुलेशन लेयर और कम्पैटिबिलिटी मोड हैं जो इसे अन्य डेटाबेस सिस्टम के व्यवहार और सिंटैक्स की नकल करने की अनुमति देते हैं। इंजन ACID ट्रांजेक्शन (मल्टी-वर्जन कॉनकरेंसी कंट्रोल के साथ), जियोस्पेशियल और JSON डेटा सपोर्ट, और उन्नत विश्लेषणात्मक विंडो फंक्शन्स जैसी व्यापक क्षमताएं प्रदान करता है। इसमें डेटा संरक्षण के लिए कंप्रेस्ड बैकअप, SQL स्क्रिप्ट रिस्टोरेशन और बड़े डेटासेट को संभालने के लिए ऑफ-हीप मेमोरी प्रबंधन के टूल शामिल हैं।
Supports the creation of user-defined aggregate functions (UDAFs) by mapping them to source code.

4,155GitHub पर देखेंVelox is a high-performance C++ query execution engine and columnar data processing library. It serves as a composable framework for implementing analytical query engines, providing a vectorized expression evaluator and a toolkit for data management systems. The project is distinguished by its use of vectorized columnar execution and arena-based memory allocation to process large-scale datasets. It features specialized optimizations such as broadcast join table caching, dynamic filter push-down, and dictionary encoding to reduce memory overhead and accelerate analytical reads. The engine cov
