Auto-Pipe, from the Stream Based Supercomputing Lab at Washington University in St. Louis, an application development environment for streaming applications that allows authoring of applications for heterogeneous systems (CPU, GPGPU, FPGA). Applications can be developed in any combination of C, C++, and Java for the CPU.
The logical query plan can be optimized, which strongly depends on the streaming model. The basic concepts for optimizing continuous queries are equal to those from database systems . If there are relational data streams and the logical query plan is based on relational operators from the Relational algebra , a query optimizer can use the ...
The flow of data is explicit, often visually illustrated as a line or pipe. In terms of encoding, a dataflow program might be implemented as a hash table, with uniquely identified inputs as the keys, used to look up pointers to the instructions. When any operation completes, the program scans down the list of operations until it finds the first ...
The Hadoop framework itself is mostly written in the Java programming language, with some native code in C and command line utilities written as shell scripts. Though MapReduce Java code is common, any programming language can be used with Hadoop Streaming to implement the map and reduce parts of the user's program. [15]
Jay Kreps introduced the kappa architecture to use a pure streaming approach with a single code base. [13] In a technical discussion over the merits of employing a pure streaming approach, it was noted that using a flexible streaming framework such as Apache Samza could provide some of the same benefits as batch processing without the latency.

Broadcast vs. cable vs. streaming: The future of television is a confusing maze for viewers. Gannett. Julie Hinds, Detroit Free Press. March 4, 2024 at 5:02 AM. What is the future of television ...
The MapR File System (MapR FS) is a clustered file system that supports both very large-scale and high-performance uses. [1] MapR FS supports a variety of interfaces including conventional read/write file access via NFS and a FUSE interface, as well as via the HDFS interface used by many systems such as Apache Hadoop and Apache Spark.
