Often see the spark of news recently,
I don't understand, search a lot of results, or do not understand,
For woman, in what situations and its effect,

PS: it Juno will also support the feature of the spark, cloud computing, the spark, so keep an eye on,
confused

Spark is a new generation of large data after the Hadoop distributed processing framework, is an extensible platform for the data analysis, it integrates the calculation of primitive memory, therefore, relative to the Hadoop cluster storage methods, it is more advantage in terms of performance, the Spark is implemented in the Scala language, and use of the language, provides a unique environment for data processing,
Spark is growing big data analysis solution has attracted much attention in the family of new members, it is not only for the distributed processing of the data set provides an effective framework, and in an efficient way (by simple Scala scripts) processing distribution data set, the Spark and Scala are actively developing stage, however, because of them is adopted in the key Internet attributes, both seem to have been a focus of attention from the open source software based Web technology transition to become,

a few upstairs said estimated is similar to baidu,,,

In fact, the spark you can think of is replaced before you use the database at the ~! Before you save the data in oracle, mysql, and now you want to store on the spark, then deposit on the spark is where? , is a memory, a relational database into non-relational database at it ~!

I am just learning soon, as is a self understanding at ~! However, should probably just like this,
