Transferred from: http://southpeak.github.io/blog/2014/07/17/ioszhong-liu-stream-de-shi-yong/Streams provide an easy way to exchange data between different and medium, which is device-independent. A stream is a sequential sequence of bits that are transmitted serially in a communication path. From an encoding standpoint, the stream is unidirectional, so the stream can be an input stream or an output stream. In addition to file-based streaming, other f

Design BackgroundSpark Thriftserver currently has 10 instances on the line, the past through the monitoring port survival is not accurate, when the failure process does not quit a lot of situations, and manually to view the log and restart processing services This process is very inefficient, so design and use spark Streaming to the real-time acquisition of the spark Thriftserver log, through the log to determine whether the service stopped service, s
-write log before the database is actually changed. This guarantees that the timestamp of the pre-write log will never lag behind the database, even if the server is suddenly crashing at the time of the write, and the data can be recovered from the pre-write log after the restart because the pre-write log retains the newer version than the database record. The asynchronous replication solution for PostgreSQL is the use of a pre-written log to transfer the pre-written log from the primary server

The live555 streaming media server is one of the related projects that I've done before in retrospect, so let's take a look at the live555 Open source framework's compilation method under Windows today.LIVE555 is a set of open-source C + + libraries that use open standard protocols (RTP/RTCP, RTSP, SIP) to process multimedia streaming data using the LGPL protocol. These libraries can be compiled into UNIX (
Many distributed computing systems can handle big data streams in real-time or near real-time. This article will briefly introduce the three Apache frameworks, and then try to quickly and highly outline their similarities and differences.Apache StormIn storm, we first design a graph structure for real-time computing, which we call topology (topology). This topology will be presented to the cluster, which distributes the code by the master node in the cluster and assigns the task to the worker no
In the following example, I will use red5 as the Streaming Media Server and use the xml configuration file reading technology, mongodobject parameter passing and event passing mechanisms (note: the event itself can store and PASS Parameters ). Read the configuration file, including the streaming media service connection address and the name of the initialized video. Code highlighting produced by Actipro

-lapse interactive voice-on-demand on the internet is a commonplace thing, but it is working on the Internet, in the more ocean over the sea of the congested links on the road, the sound of delay and loss is often difficult to accept. Even in the Continental region, the quality of the sound is greatly reduced due to the congestion at the peak. Summed up, the current multimedia network application to focus on the problem is: ① increase network bandwidth, ② reduce delay (delay), ③ reduce jitter (
