    Amethyst is a framework intended to help in creation of applications with the MVC or a similar pattern. The project consists of low- and high-level API. Low-level API is responsible for exchanging properties (as Map) between various components. A component can be for example model, view or controller as in the MVC pattern. The main class is a class named Communicator. Communicator class defines the structure of components' system, provides communication channel between them and life-cycle management for each one. It also provides ability to run components in different threads (multitasking). IT CAN SUCCESSFULLY SPLIT MODEL'S THREAD FROM GUI THREAD

    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.

    Apache Beam

    Apache Beam

    Unified programming model for Batch and Streaming

    Apache Beam is an open source, unified programming model to define both batch and streaming data-parallel processing pipelines, as well as certain language-specific SDKs for constructing pipelines and Runners. These pipelines are executed on one of Beam’s supported distributed processing back-ends, which include Apache Apex, Apache Flink, Apache Spark, and Google Cloud Dataflow. Beam is especially useful for Embarrassingly Parallel data processing tasks, and caters to the different needs and backgrounds of end users, SDK writers and runner writers.

    Apache Flink

    Apache Flink

    Stream processing framework with powerful stream

    Apache Flink is a distributed engine for stateful computations over data streams and batches, designed for low-latency processing at scale. Its core runtime executes dataflow graphs with fine-grained backpressure and checkpointing, allowing applications to recover consistently from failures. Flink’s event-time model and watermarks enable accurate out-of-order processing, windowing, and complex time semantics that typical real-time systems struggle with. Developers program against high-level APIs—DataStream and Table/SQL—to express transformations, joins, and stateful patterns, while specialized libraries support CEP, machine learning workflows, and connectors. A rich connector ecosystem integrates with systems like Kafka, Kinesis, filesystems, JDBC sources/sinks, and object stores. Deployments span Kubernetes, YARN, Mesos, and standalone clusters, and operational features such as savepoints, state backends, and metrics make long-running jobs manageable in production.

    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.
