Because of the differences between relational database manipulation languages and object-oriented languages, we still need to spend a lot of time building a bridge between database and Java applications. In general, we can write our own mapping layer (mapping layer) or use a third party ORM (Object Relational Mapper) Object Relational mapping framework, such as Hibernate. ORM frameworks are easy to use, but how to
Previously wrote a version of the picture "lazy load" article, just the weekend in the collation of documents, and probably read the previous code found that there are many can optimize the place.This article is mainly in conjunction with the " JavaScript waterfall streaming picture lazy loading instance " To see the picture "lazy load" some knowledge.
The theme of the picture "lazy load":Load the picture as needed, which means that you need to displ
1. Join for different time slice data streams
After the first experience, I looked at Spark WebUi's log and found that because spark streaming needed to run every second to calculate the data in real time, the program had to read HDFs every second to get the data for the inner join.
Sparkstreaming would have cached the data it was processing to reduce IO and increase the speed of computation, but since our scenario now is to inner join with data strea

This is like Feng Shui in the past, each area has its own dragon vein, Spark is where the dragon vein, its dragon Cave or the key point is sparkstreaming. This is one of the conclusions we know very clearly in the last lesson. And in the last lesson, we adopted the way of dimensionality reduction. The so-called dimension of the way, ref
Now the continuous development and progress of network technology, the arrival of big data, so that network bandwidth increases rapidly. Because of the progress of the Times, the network and streaming media technology to show the opportunity and display, and also for the campus video Live network transmission audio and video data has laid a good foundation. The transformation of education mode of information digital education provides a good network e

For this reason, I have compiled some protocol information about common streaming media, hoping to help me solve the live streaming latency. 1. rtmp (real time messaging protocol)Real-time message transmission protocol released by Adobe.

A streaming application often requires 7*24 uninterrupted running, so it needs to be able to withstand unexpected abilities (such as machine or system hangs, JVM crash, etc.). To make this possible, Spark streaming needs to checkpoint enough information to a fault-tolerant storage system in order for application to r

Overview
Kafka is a distributed publish-subscribe messaging system, which is simply a message queue, and the benefit is that the data is persisted to disk (the focus of this article is not to introduce Kafka, not much to say). Kafka usage scenarios are still relatively large, such as buffer queues between asynchronous systems, and in many scen
