SPARK
Spark
? Spark adalah engine analitik umum (general engine) yang cepat dalam pemrosesan large-scale Big Data.
? Salah satu project Apache, free dan open-source ? Spark merupakan general purpose cluster engine yang
mendukung konsep sistem terdistribusi dengan application programming interface (APIs) ? Bisa digunakan Java, Scala, Python, dan R serta beberapa library untuk streaming, graph dan juga machine learning (mesin pembelajaran yang merupakan sekumpulan dari banyak algoritme di dalamnya
Spark
? Spark disebut juga dengan "Lightning Fast Cluster Computing".
? Spark 100x lebih cepat dari Hadoop MapReduce pada memory, dan 10x lebih cepat pada disk
? Spark dapat dijalankan standalone, di Hadoop, Mesos, atau di cloud.
? Spark dapat mengakses beragam sumber data termasuk HDFS, Cassandra, HBase, dan S3.
Key Features
? Speed
? Run workloads 100x faster
? Ease of Use
? Write applications quickly in Java, Scala, Python, R, and SQL.
df = spark.read.json("logs.json")df.where("age > 21") .select("name.first").show()
Spark's Python DataFrame API Read JSON files with automatic schema inference
Key Features
? Generality
? Combine SQL, streaming, and complex analytics.
? Runs Everywhere
? Spark runs on Hadoop, Apache Mesos, Kubernetes, standalone, or in the cloud. It can access diverse data sources.
