    Android Easy MultiDex

    Android Easy MultiDex

    Android, multidex, splitdex, subpackage plugin

    Android, multidex, splitdex, subpackage plugin. The Gradle script was integrated into the plug-in, so that only one configuration file needs to be maintained. Readers can choose separate configuration or integrated configuration according to their own needs. In this way, we maintain the number of methods of the main Dex at about 15,000, and we no longer have to worry about the number of methods. Through the above official subcontracting, the original Dex has been divided into 1 master Dex and more slave Dex. The main Dex contains all 4 major components, Application, Annotation, multidex, etc. and their necessary direct dependencies. Since the number of our methods has reached 16W, hundreds of activities were all stuffed into the main Dex, and the main Dex was successfully exploded.

    Android-Plugin-Framework

    Android-Plugin-Framework

    Android Plugin Framework

    Android-Plugin-Framework is an Android plug-in framework, which is used to run plug-in apk without installation through dynamic loading. Although this framework supports independent plug-ins, the goal is not to support any third-party apps, unlike products such as Parallel Space or App Clone. Compared with any third-party app, non-independent plug-ins can predict which system APIs and features they use, and all behaviors are predictable. And any third-party app is unpredictable. The approach of the framework is to hook on demand, that is, which system features and APIs need to be used, and which features and APIs are supported. This approach is perfectly sufficient for developing non-standalone and second-party standalone plugins. Currently, support for common features and APIs has been added. If the API you want to use is not yet supported, please contact the author.

    Apache InLong

    Apache InLong

    Apache InLong - a one-stop integration framework for massive data

    Apache InLong is a one-stop integration framework for massive data that provides automatic, secure and reliable data transmission capabilities. InLong 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.

    Apache Sedona

    Apache Sedona

    Cluster computing framework for processing large-scale geospatial data

    Apache Sedona™ is a cluster computing system for processing large-scale spatial data. Sedona extends existing cluster computing systems, such as Apache Spark and Apache Flink, with a set of out-of-the-box distributed Spatial Datasets and Spatial SQL that efficiently load, process, and analyze large-scale spatial data across machines. According to our benchmark and third-party research papers, Sedona runs 2X - 10X faster than other Spark-based geospatial data systems on computation-intensive query workloads. According to our benchmark and third-party research papers, Sedona has 50% less peak memory consumption than other Spark-based geospatial data systems for large-scale in-memory query processing. Sedona offers Scala, Java, Spatial SQL, Python, and R APIs and integrates them into underlying system kernels with care. You can simply create spatial analytics and data mining applications and run them in any cloud environments.

    Apollo

    Apollo

    Java libraries for writing composable microservices

    Apollo is a set of Java libraries that we use at Spotify when writing micro-services. Apollo includes features such as an HTTP server and a URI routing system, making it trivial to implement RESTful services. Apollo has been used in production at Spotify for a long time. As a part of the work to release version 1.0.0 we are moving the development of Apollo in to the open. The apollo-api library defines the interfaces for your request routing and request/reply handlers. The apollo-core library manages the lifecycle (loading, starting, and stopping) of your service and defines a powerful module system for adding functionality to an Apollo assembly. You do not usually need to interact directly with apollo-core; think of it merely as “plumbing.” The apollo-http-service library is a standardized assembly of Apollo modules. It incorporates both apollo-api and apollo-core and ties them together with several other useful modules to get a standard API service.
