Overview of Spark batch Corporate Training:
Apache Spark is a data processing framework that can quickly perform processing tasks on very large data sets, and can also distribute data processing tasks across multiple computers, either on its own or in tandem with other distributed computing tools. These two qualities are key to the worlds of big data and machine learning, which require the marshalling of massive computing power to crunch through large data stores. Spark also takes some of the programming burdens of these tasks off the shoulders of developers with an easy-to-use API that abstracts away much of the grunt work of distributed computing and big data processing.
Basically, while storing data in RDD, data is stored in memory for as long as you want to store. It improves the performance by an order of magnitudes by keeping the data in memory.
Spark Lazy Evaluation means the data inside RDDs are not evaluated on the go. Basically, only after an action triggers all the changes or the computation is performed. Therefore, it limits how much work it has to do.
If any worker node fails, by using lineage of operations, we can re-compute the lost partition of RDD from the original one. Hence, it is possible to recover lost data easily.
Immutability means once we create an RDD, we can not manipulate it. Moreover, we can create a new RDD by performing any transformation. Also, we achieve consistency through immutability.
In in-memory, we can store the frequently used RDD. Also, we can retrieve them directly from memory without going to disk. It results in the speed of the execution. Moreover, we can perform multiple operations on the same data. It is only possible by storing the data explicitly in memory by calling persist() or cache() function.
Basically, RDD partition the records logically. Also, distributes the data across various nodes in the cluster. Moreover, the logical divisions are only for processing and internally it has no division. Hence, it provides parallelism.
While we talk about parallel processing, RDD processes the data parallelly over the cluster.
To compute partitions, RDDs are capable of defining placement preference. Moreover, placement preference refers to information about the location of RDD. Although, the DAGScheduler places the partitions in such a way that task is close to data as much as possible. Moreover, it speeds up computation.
Generally, we apply coarse-grained transformations to Spark RDD. It means the operation applies to the whole dataset not on the single element in the data set of RDD in Spark.
There are several types of Spark RDD. Such as: RDD [int], RDD [long], RDD [string].
There are no limitations to use the number of Spark RDD. We can use any no. of RDDs. Basically, the limit depends on the size of disk and memory.
