DL-4: Add repackaging script this pull request only contains the script to repackage files. run it at the root directory of the project - **./scripts/dev/repackage.sh** once the script is done, run "**mvn clean apache-rat:check package windbags:check**" to verify everything work. then you can commit the changes with the modified files. /cc leighst sijie Author: Khurrum Nasim <email@example.com> Reviewers: Sijie Guo <firstname.lastname@example.org> Closes #95 from khurrumnasimm/kn/repackaging_script
Apache DistributedLog (DL) is a high-throughput, low-latency replicated log service, offering durability, replication and strong consistency as essentials for building reliable real-time applications.
The Apache DistributedLog project is in the process of incubating. This includes the creation of project resources, the refactoring of the initial code submissions, and the formulation of project documentation, planning and the improvements of existing user and operation documents. Any feedback and contributions are welcome.
DL is able to provide milliseconds latency on durable writes with a large number of concurrent logs, and handle high volume reads and writes per second from thousands of clients.
Messages are persisted on disk and replicated to store multiple copies to prevent data loss. They are guaranteed to be consistent among writers and readers in terms of strict ordering.
DL provides an efficient service layer that is optimized for running in a multi- tenant datacenter environment such as Mesos or Yarn. The service layer is able to support large scale writes (fan-in) and reads (fan-out).
DL supports various workloads from latency-sensitive online transaction processing (OLTP) applications (e.g. WAL for distributed database and in-memory replicated state machines), real-time stream ingestion and computing, to analytical processing.
To support a large number of logs for multi-tenants, DL is designed for I/O isolation in real-world workloads.
DL has a modern layered architecture design, which separates the stateless service tier from the stateful storage tier. To support large scale writes (fan- in) and reads (fan-out), DL allows scaling storage independent of scaling CPU and memory.
