Google File System (GFS or GoogleFS, not to be confused with the GFS Linux file system) is a proprietary distributed file system developed by Google to provide efficient, reliable access to data using large clusters of commodity hardware. Google file system was replaced by Colossus in 2010.
Bigtable development began in 2004. [1] It is now used by a number of Google applications, such as Google Analytics, [2] web indexing, [3] MapReduce, which is often used for generating and modifying data stored in Bigtable, [4] Google Maps, [5] Google Books search, "My Search History", Google Earth, Blogger.com, Google Code hosting, YouTube, [6] and Gmail. [7]
Developers have read-only access to the file system on App Engine. Applications can use only virtual file systems. App Engine can only execute code called from an HTTP request (scheduled background tasks allow for self-calling HTTP requests). Users may upload arbitrary Python modules, but only if they are pure Python.
Bazel is extensible with the Starlark programming language. [13] Starlark is an embedded language whose syntax is a subset of the Python syntax. However, it doesn't implement many of Python's language features, such as the ability to access the file I/O, in order to avoid extensions that could create side-effects or create build outputs not known to the build system itself.
CloudStore supports incremental scalability, replication, checksumming for data integrity, client side fail-over and access from C++, Java and Python. There is a FUSE module so that the file system can be mounted on Linux. In September 2007, Kosmix published Kosmosfs as open source. [1] The last commit activity was in 2010.
Google I/O is Google's largest developer event, which is usually held in May at the Shoreline Amphitheatre, Mountain View. Google Summer of Code is a mentoring program to find students for open source projects. In 2016, the program received nearly 18,980 applications. Google Code Jam is an international programming competition.
Ghemawat's work at Google includes: Original design of Protocol Buffers, an open-source data interchange format. MapReduce, a system for large-scale data processing applications. Google File System, is a proprietary distributed file system developed to provide efficient, reliable access to data using large clusters of commodity hardware.
Development of GFS began in 1995 and was originally developed by University of Minnesota professor Matthew O'Keefe and a group of students. [3] It was originally written for SGI 's IRIX operating system, but in 1998 it was ported to Linux (2.4) [ 4 ] since the open source code provided a more convenient development platform.
