Distributed in-memory file system

Distributed file systems are complex and adding an inmemory layer with its compression and limitations add operational overhead. You wouldnt replace an on disk distributed file system with an inmemory one, rather you would extend it.Apr 28, 2013  Tachyon: An open source, distributed, faulttolerant, inmemory file system. In particular a system like Tachyon will appeal to data scientists who rely on workflows that use a variety of tools: their resulting data analytic pipelines will run much faster. To that end, its creators simulated a realworld4 data pipeline comprised of 400 steps, and found that Tachyon resulted in 17x endtoend latency distributed in-memory file system

GassyFS is a FUSE based file system that stores data in distributed remote memory. Remote memory is managed and accessed using GASNet, which supports RDMA over a wide variety of highperformance network interconnects, as well as supporting slower network access methods such as UDP that are useful for development.

Li describes the file system as being simultaneously memorycentric, virtual, and distributed. While its memory centric and resides primarily in DRAM, it can also work with data sitting on SSDs and hard disks. Its virtual in that it can sit transparently next to existing file systems One of the unique capabilities of Apache Ignite is a distributed inmemory file system called Ignite File System (IGFS). IGFS delivers a similar functionality to Hadoop HDFS, but only inmemory. In fact, in addition to its own APIs, IGFS implements Hadoop FileSystem API and can be transparently plugged into Hadoop or Spark deployments. distributed in-memory file system Similar Functionality to HDFS But InMemory. With the GridGain Distributed InMemory File System, the data from each file is split on separate data blocks and stored in cache. Developers can access each files data with a standard Java streaming API. For each part of the file, a developer can calculate an affinity and process
