Apache InLong is a one-stop, full-scenario integration framework for massive data that supports Data Ingestion, Data Synchronization and Data Subscription, and it provides automatic, secure and reliable data transmission capabilities. InLong also supports both batch and stream data processing at the same time, which offers great power to build data analysis, modeling and other real-time applications based on streaming data.

InLong (应龙) is a divine beast in Chinese mythology who guides the river into the sea, and it is regarded as a metaphor of the InLong system for reporting data streams.

InLong was originally built at Tencent, which has served online businesses for more than 8 years, to support massive data (data scale of more than 80 trillion pieces of data per day) reporting services in big data scenarios. The entire platform has integrated 5 modules: Ingestion, Convergence, Caching, Sorting, and Management, so that the business only needs to provide data sources, data service quality, data landing clusters and data landing formats, that is, the data can be continuously pushed from the source to the target cluster, which greatly meets the data reporting service requirements in the business big data scenario.

Apache InLong offers a variety of features:

  • Ease of Use: a SaaS-based service platform. Users can easily and quickly report, transfer, and distribute data by publishing and subscribing to data based on topics.
  • Stability & Reliability: derived from the actual online production environment. It delivers high-performance processing capabilities for 10 trillion-level data streams and highly reliable services for 100 billion-level data streams.
  • Comprehensive Features: supports various types of data access methods and can be integrated with different types of Message Queue (MQ). It also provides real-time data extract, transform, and load (ETL) and sorting capabilities based on rules. InLong also allows users to plug features to extend system capabilities.
  • Service Integration: provides unified system monitoring and alert services. It provides fine-grained metrics to facilitate data visualization. Users can view the running status of queues and topic-based data statistics in a unified data metric platform. Users can also configure the alert service based on their business requirements so that users can be alerted when errors occur.
  • Scalability: adopts a pluggable architecture that allows you to plug modules into the system based on specific protocols. Users can replace components and add features based on their business requirements.

When should I use InLong?

InLong aims to provide a one-stop, full-scenario integration framework for massive data, users can easily build stream-based data applications. It supports Data Ingestion, Data Synchronization and Data Subscription at the same time, and is suitable for environments that need to quickly build a data reporting platform, as well as an ultra-large-scale data reporting environment that InLong is very suitable for, and an environment that needs to automatically sort and land the reported data.

You can use InLong in the following ways:

  • Integrate InLong, manage data streams through SDK.
  • Use the InLong command-line tool to view and create data streams.
  • Visualize your operations on InLong dashboard.
